Discover our range of containment systems to improve Road Safety

Ensuring road safety is everyone's responsibility. Drivers should be aware that each journey by car can have serious consequences if they are not driven carefully, but it is also necessary that the public authorities that manage transport infrastructures guarantee safe roads to minimize the severity of accidents as much as possible. This is something that is already being done by both parties: drivers are increasingly responsible behind the wheel and the authorities are working to build safe roads. Proof of this are the results of the latest report from the European Transport Safety Council (ETSC), which indicates that between 2001 and 2020 the accident rate on Spanish roads fell from 5,517 victims to 1,370. That is, 75.2% less. These figures position Spain as the country in Europe in which deaths in traffic accidents have fallen the most during this century. In this sense, Road Safety studies and improvement of the most conflictive points are absolutely essential to progressively improve the road network. One of the most important elements of your safety equipment is containment systems.


Infrastructures for Road Safety: Vehicle containment systems

What is a containment system?

Vehicle restraint systems are safety barriers located on the roads to mitigate the consequences of accidents due to exits.

Road exits make up between 35% and 40% of road accidents. Given these high percentages, it is convenient to ask ourselves what type of containment systems it is necessary to install on those roads with a high risk of accidents. Said vehicle containment systems ‘act’ in various situations such as:

  • When the vehicle leaves the road in an uncontrolled way.
  • When there is a risk of falling down steep slopes.
  • When the vehicle invades another lane.
  • When there are obstacles on the road with which the vehicle can impact.

In these types of situations, the absence of containment systems is very likely to lead to a fatal outcome, which is why their installation is so important.


Factors to take into account for the installation of Vehicle Containment Systems

The following factors must be considered in deciding in which situations it will be necessary to install vehicle restraint systems:

  • Type of road: If it is a conventional road, highway or highway.
  • Characteristics of the section: If it is a curve or a straight section.
  • Traffic intensity and composition: This factor refers to the number of each type of vehicle that circulates on the section in question.
  • Existing risks on the road: Obstacles, steep slopes, that there are other roads that could be invaded ...
  • Distance between road hazards.

After analyzing these factors, it will be decided whether a vehicle restraint system should be installed in the section to mitigate the consequences of accidents. If the study of these factors indicates the need for its installation, the next step is to decide what type of vehicle containment system is required, for which the following parameters are met:

  • Containment level: Refers to the capacity of the containment system to retain the vehicle in the event of a collision, redirecting it to the road in stable conditions, that is, the vehicle does not overturn or the containment system does not penetrate inside.
  • Impact severity: The risk of the occupants when the vehicle collides in front of the restraint system.
  • System deformation: The measurement of the degree of deformation of the containment system when the impact occurs, serves to define the distance at which said infrastructure has to be installed with respect to the dangerous area or obstacle.
  • Redirection capacity: Ability of the vehicle restraint system to change the trajectory of the passenger car when the crash occurs, allowing the exit to be as parallel as possible to the direction of traffic.


Types of Metal Vehicle Containment Systems

After carrying out the previous analysis, we will proceed to select the most suitable containment system. At Metalesa, we are experts in the design, manufacture and installation of vehicle restraint systems and we have a wide range that allows us to adapt to all existing situations in terms of Road Safety.


Steel Bridge Parapet META13

This type of vehicle containment system is installed on the edges of bridge decks, supporting wall crowns, passage works… It is a H2 level containment system.

Some of the main advantages of the Steel Bridge Parapet META13 are the flexibility of the containment system, its fusible anchoring system that allows a simple and quick replacement in the event of a crash, and its versatility, since it allows it to function as a vehicle containment system. and pedestrians installing a grid.

It is a device approved according to the UNE EN 1317 parts 1 and 2 standard, which together with compliance with part 5 in terms of production control, has obtained the CE marking.

Steel Bridge Parapet META16

The Steel Bridge Parapet META16 is our H3 containment system, which also has the CE marking after passing rigorous full-scale laboratory tests.

Some of the advantages of this vehicle restraint system are the following: It is light and of small dimensions, it allows the installation of vandal-proof fences and the placement of acoustic screens at a very short distance from the parapet, and due to its reduced number of components the assembly it's simple.

Impact End Terminals

Impact End Terminals are equipment that is characterized in that they are always attached to the end of a vehicle restraint system. They cannot be installed autonomously.

We have several models tested in accordance with the European standard prEN 1317-7, all of which provide the flexibility of joining with double or triple wave bionds, or with normal or double bionds (on both sides).

Crash Cushions

A Crash cushion or shock absorber is a vehicle restraint system that absorbs frontal or side impacts without the risk of intrusion of components in the vehicle compartment, being its installation more and more frequent since it allows to significantly reduce the victims in accidents.

We have a wide variety of models that can be installed on concrete slab or directly on the ground. In case of impact, the infrastructure is easy to repair or replace.

Mixed Parapet PXP

It is a mixed vehicle containment system, as it is made up of a concrete parapet and a metal railing. The latter is installed on the concrete parapet, which guarantees a better containment system against the collision of a heavy vehicle.

In addition, its aesthetics provide excellent integration on the tracks, it is easy to install and we have several models of handrails: With a through tube to a ring welded to each support, with a tube welded directly to each support, or other models according to installation conditions.

At Metalesa we are aware that our products save lives, and that is why we have a great responsibility. In this sense, it is not only important that the authorities worry about the installation of containment systems on the roads, but also to ensure that these infrastructures are of quality, there is a lot at stake. From Metalesa we can guarantee that quality in our products to ensure safe roads.

World Pedestrian Day, for safe cities

"World Days" generally refer to an event from the past that we recall to celebrate. But the truth is that these days do not always represent something to be celebrated, but instead occasions of awareness.

Today is Pedestrian World Day, and it is not exactly a day to celebrate. It is a day that has its origin in memory of the first recorded pedestrian victim: Bridget Driscoll was run over on August 17, 1897 in London, dying on the spot. We don't usually start our articles on Road Safety with this crudeness. But that is the reality. Since that day, the list of registered deaths by car accidents has unfortunately continued to increase.

The importance of 'celebrating' Pedestrian World Day every day

The objective of Pedestrian World Day is to join efforts to guarantee a much safer traffic for pedestrians, promoting adequate spaces to move around in cities, and remembering the obligations that both drivers and pedestrians have.

Some figures to consider

In the Spanish DGT report for 2019, the number of deaths on the roads was 1,755 people, of which a large part, specifically 53%, were considered vulnerable, that is, pedestrians, cyclists and motorists. In addition, the report also reported a 6% increase in deaths in cities, with the vast majority of deaths being over 65 years of age. That said, we insist on the importance of being responsible, whether we are in the 'role' of pedestrian or driver, both for our own safety and that of others.

What to do to be a good pedestrian?

They may seem obvious, but believe us, it never hurts to remember these tips.

  • Always cross at the pedestrian crossing.
  • Respect traffic lights.
  • Always look both ways before crossing, even if the road you are going to cross is one-way.
  • Reduce the use of technology on the go. It is advisable to avoid using the mobile phone as it is undoubtedly a great distraction, not only when we are driving but also when we are walking around the city. In addition, the use of headphones is not recommended since the ideal is to have all our senses on the road.

 What to do to be a good driver on urban roads?

  • Respect the signs and speed limits.
  • Respect the cyclists who circulate on the road if there is no bike lane, since they have the same right to circulate on public roads.
  • Maintain a safe distance between vehicles.
  • Avoid distractions such as mobile phone use.

Urban Road Safety. What is it?

At Metalesa, we have always been concerned about raising awareness about the dangers on the roads, whether on the road or in urban areas, for this reason, we consider ourselves to be the standard bearers of the Road Safety concept.

And it is that our company philosophy goes beyond designing, manufacturing and installing products for road safety, since we also carry out this work of social awareness. However, it must be admitted that when the word of ‘Road Safety’ is heard, the majority of road safety education comes to mind, focused on safety at the wheel. However, Road Safety encompasses all areas in which any type of urban or inter-urban displacement occurs. In this sense, 'Urban Road Safety' takes on special relevance, which focuses in much greater detail on the particular cases of road safety in the urban environment.

Given that in today's article we are talking about World Pedestrian Day, it is an ideal occasion to discuss the concept of Urban Road Safety, since, although it is not exclusively linked to pedestrian safety, both pursue common objectives.

Urban Road Safety is the set of actions aimed at preventing, controlling and reducing the risk of accidents in the movement of people, whether on foot or by vehicle, within urban centers.

To put Urban Road Safety into practice, more and more cities have chosen to apply urban measures that include the reorganization of urban space and the promotion of the adaptation of user behavior to this new space.

A bit of urban history: The Car Cities

If we look at it, most cities are designed under an urbanization model that generalizes the mobility of private vehicles, and this situation began to occur approximately from the first half of the 20th century.

This fact gave rise to the ‘Car Cities’, cities in which the infrastructures at the service of the circulation of vehicles occupy most of the urban centers, so the chances of suffering accidents while traveling are considerably increased.

However, more and more cities are choosing to reorganize their urban designs and convert urban centers into more pedestrian spaces, and therefore safer in order to ensure Urban Road Safety. For example, the Plaza del Ayuntamiento de Valencia is now 100% pedestrian after the urban reorganization works that were carried out a few months ago.

Decisions and initiatives of city councils to promote Urban Road Safety

In addition to converting urban centers into pedestrian spaces, municipalities also carry out other measures to guarantee Urban Road Safety:

  • Improve the design of the streets and the signage to guarantee the coexistence of all the displacement systems.
  • Control and sanction road indiscipline more effectively.
  • Consider Urban Road Safety as a public health issue.
  • Act in the field of citizen training in Road Safety values.
  • Implement monitoring systems to improve the analysis of information on mobility and urban accidents.

Our products to guarantee Urban Road Safety

At Metalesa we like to say that "protection is our goal," and in order to achieve this goal, we take care of designing, manufacturing and installing products that guarantee safety in various fields. In the case of urban Road Safety, our railings are designed to protect pedestrians and to delimit spaces between pedestrian and road areas, among many other applications.

Cyclopedestrian railings

The cyclopeatonal railing is a restraint system for both pedestrians and cyclists who circulate on urban roads, so that it helps to reduce the accident rate on pedestrian or cycling routes. In addition, they adapt perfectly to the aesthetics of the urban area.

Steel railings

Steel railings are also pedestrian restraint systems. At Metalesa we have a wide variety of models capable of integrating perfectly with the landscape, since we have many thermo-lacquered finishes and colors.

Stainless steel railings

Their aesthetic appearance makes them very appropriate to be installed in any type of urban area, guaranteeing the safety of pedestrians. We have a wide catalogue with unique and modern designs, in addition, we can manufacture stainless steel railings with custom designs if the client requires it.

Railings with steel cable

Steel cable railings are one of the most elegant, and of course, safe options to ensure the safety of pedestrians.

Railings with perforated sheet

In the same way as the metal railings with steel cable, the railings with perforated sheet also present a very attractive appearance for installation in cities, since they can be manufactured with any perforated design in the material. Depending on the type of perforation, you can create a design that provides safety to the pedestrian without sacrificing aesthetics on the streets. Because ensuring safety does not mean giving up good taste!

The truth is that it is in everyone's hands to be able to reach the goal of achieving a 0% accident rate in cities. Little by little we are taking steps that bring us closer to achieving it, but there is still much to do. From Metalesa, information and awareness articles like the one you just read or through the installation of our products, we try to do our bit. And you, what are you willing to do for your safety and that of those you care about?

How to protect my house from the noise of cars while maintaining the views

Are you staying in a house in a small town on the coast or in the mountains? Do you enjoy views of the sea or nature? If the answer is yes, we can imagine the sensations that have come to mind: calm, disconnection, well-being, happiness ... However, sometimes there are external factors that interrupt this atmosphere of tranquility, such as noise from cars traveling in nearby areas.

It is a shame that the noise pollution caused by traffic interrupts your state of serenity, because excess noise is not only annoying, but is also harmful to health, especially in the face of constant exposure to high noise levels.

At Metalesa we ensure the protection of people, and therefore in this article we bring you the solution to end the noise of cars without giving up wonderful views.

Soundscape and noise pollution

The term 'noise pollution' is likely to be much more familiar to you than 'soundscape', so let's start by explaining the latter.

What is the soundscape?

The Soundscape refers to the set of characteristic sounds of a certain place. That said, there are several types of soundscapes:

  • Natural soundscapes: are those that are produced due to the sound of animals, vegetation moving with the wind, sea waves, raindrops ...

  • Artificial soundscapes: are those produced by human activities, the use of machinery, traffic ...

In general, natural soundscapes are positive, since they generate a type of noise that is neither annoying nor harmful to humans. However, man-made soundscapes are often the cause of noise pollution, and what is even more serious, noise pollution can eventually take over natural soundscapes.

Given this fact, from Metalesa we recommend installing acoustic screens to eliminate excess noise, and thus restore the natural state of the area in which your home is located.


Acoustic screens to absorb noise

Acoustic screens are made up of panels capable of absorbing or attenuating excess noise. At Metalesa, one of our star products is precisely acoustic screens, which is why we have a wide variety of types and models of acoustic panels.

With the installation of acoustic screens you will be able to live peacefully at home without the annoying noise due to traffic interrupting your tranquility. That said, if what we want is to maintain the views, not all acoustic screens will work for us. Our recommendation is the methacrylate acoustic screen thanks to its transparent panel.

Methacrylate acoustic screen to maintain views

The methacrylate acoustic screens are made of polymethacrylate sheets, and can be colored or colorless, although as a general rule if we want to enjoy the views we will opt for the colorless ones; they can also incorporate different vinyl models. In any case, we always adapt to the needs of each client.

Its height and separation dimensions are calculated based on an acoustic study, the terrain and the action of the wind in the area. Likewise, the acoustic panels can be adapted to different widths of beam profiles.

More advantages of methacrylate acoustic screens

The methacrylate acoustic panels fulfill a double acoustic and aesthetic function, as they guarantee noise absorption while integrating perfectly into the landscape, allowing tenants to enjoy the views around them.

  • The methacrylate acoustic screen is easy to install.
  • There is the possibility of choosing between various designs of acoustic panels, which give rise to different combinations resulting in mixed shielding.
  • Methacrylate acoustic screens are highly resistant to adverse weather conditions, such as the action of wind or rain.
  • If the customer needs colored acoustic panels, it is possible thanks to the galvanized and thermo-lacquered components of the acoustic panels, in different standard colors from the RAL chart.
  • All our acoustic screens, including the methacrylate acoustic screen, have been mechanically tested according to the EN 1794-1 standard.

The methacrylate acoustic screens are the perfect solution to guarantee your well-being in your home, while you have the pleasure of enjoying the landscape that surrounds you. Be it the beach, nature, beautiful views in urban areas ... We all deserve to live in a soundscape in which we can feel comfortable.

This summer, Road Safety on the roads

The time most desired by most has finally arrived, the summer holidays. Heat, beach, disconnection from work and the daily routine ... Unfortunately, the other side of the coin is the usual increase in traffic accidents due to the enormous volume of vehicles moving on the roads.

In addition, this year we are facing a somewhat different summer, as we come from a time marked by mobility restrictions and the health emergency due to COVID-19. For a long time we have had to stay in our regions without the possibility of vacations or travel, so it is natural that with the arrival of good weather there is a significant increase in national travel, and with the need to be extremely careful on the roads.

Road Safety is everyone's business. If we are all aware of the importance of being responsible when driving, we will be able to minimize the risk of serious accidents.

Increased risks on the roads in summer

In addition to the characteristic increase in summer traffic, there are other typical summer factors that pose an added risk on the roads and that must be taken into account.

Caution with heat

In Spain, on the hottest days of summer, the temperature of a car exposed to the sun for a long period of time can exceed 50 degrees, which is a risk when driving. For this reason, before getting in the car and starting the trip, it is recommended to ventilate it by opening windows and doors, turning on the air conditioning and not starting the trip until the interior of the vehicle has acclimatized. If possible, the ideal is to avoid driving in the hottest hours of the day.

Take care of your hydratation and never drink alcohol

Lack of hydration can lead to serious risks while driving. The most common symptoms of dehydration are usually fatigue and drowsiness ... It is recommended not to wait to experience these signs to drink water. Always keep a bottle of water on hand in your vehicle and drink frequently, even if you don't feel particularly thirsty.

It's also a no-brainer, and hundreds of drivers are penalized every day for exceeding the permitted alcohol level behind the wheel. Do not drink and drive!

Food before and during your trip

If we are going to take long trips in summer, it is important to eat light meals. Otherwise, digestive discomfort can occur that can distract us from driving and affect Road Safety, and also cause drowsiness.

Always travel with suitable and comfortable cloting

Beyond driving in loose fitting, comfortable clothing, it is especially important to note that flip flops should not be worn. The risks of driving with this type of footwear are very serious: they can get caught between the pedals, slip ... and prevent reacting in time in the event of an accident.

That sunglasses are never missing

Lack of vision can be one of the main reasons for accident risk. Therefore, it is advisable to wear polarized sunglasses to avoid glare and prevent eye fatigue.

Check your vehicle before and during the journey

It is important to thoroughly check the vehicle before any trip, and especially if it is a long journey. Tires, brakes, check the oil level, the coolant level, check that the lighting devices are working, make sure that the air filter is clean and always wear vests and safety triangles.

 Calculate your route previously

Improvisation can be part of the unforgettable trip, but in driving it is not recommended. The ideal is to plan the route to your destination in advance, take into account the stops to rest ... In addition, this way you will avoid being constantly aware of the GPS and you will pay more attention to the road. And of course, the use of mobile phones while driving, unless it is to use it as a passive GPS, is totally prohibited.

Always control your speed

We know, controlling speeding is something very obvious when we go on a trip. But still every day traffic accidents happen precisely due to speeding. Remember, no matter how expert you are at the wheel, extreme caution on the road is a great responsibility that we must all carry out.

Travel accompanied

It is always important to ensure Road Safety, but the commitment is even greater when we transport more people in our vehicle. The co-pilot has to try not to over-entertain the driver to avoid confusion, and in the case of traveling with children, you have to find ways to entertain them using iPads, reading stories ... And of course, it is mandatory to insist that the occupants use the seat belt.

Now you know the most important points to keep in mind when taking a trip during this summer vacation. Today's article we want to serve as a guide that you can always turn to whenever you are going on a road trip. Even so, it is always advisable to visit the DGT website for any notice or news of interest.

At Metalesa, protection is our goal

Our mission is the protection of people. As experts in Road Safety, our activity consists of designing, manufacturing and installing infrastructures specially designed to guarantee the safety of people.

Products for Road Safety on highways


Los pretiles para carreteras son sistemas de contención para puentes. En Metalesa disponemos del pretil metálico META13 y el pretil metálico META16, los cuales han sido homologados por la norma UNE EN 1317.

Highway parapets are restraint systems for bridges. At Metalesa we have the META13 metal parapet and the META16 metal parapet, which have been approved by the UNE EN 1317 standard.

Transitions to concrete barriers

Highway transitions are used to link different vehicle restraint systems, such as a parapet and a concrete barrier. Our transitions are homologated by the French standard NF 058.

Impact terminals 

They are road safety devices that are placed at the ends of the parapets or containment barriers, as a safe ending element. We have several models of impact terminals, which share a series of characteristics such as the possibility of allowing the connection with a double or triple wave bionde, and that all have been tested according to the European standard prEN 1317-7.

Shock atenuators

Also called shock absorbers, their function is to absorb the impact of the car in the event of a crash. They differ from containment system terminals in that they can be installed in isolation, without being connected to any other system. In addition, in case of impact it is easy to repair.

Having said all this, from Metalesa we want to remember that Security does not go on vacation. Our purpose is to protect society through our products for Road Safety and to educate drivers to have an unforgettable, fun and above all safe vacation. Can you help us achieve this goal?

Security fences for parks and schools

Raising awareness about road safety is an issue that should interest everyone: drivers, pedestrians, cyclists and of course, older people and children, who in many occasions are not aware of the danger of certain situations. In this sense, it is important to educate our little ones in Road Safety, not to forget that places such as schools and playgrounds must adopt safety measures to avoid accidents.

As you well know, protection is our goal, and today's article will refer to minimize the risks for children thanks to our security fences and handrails.

Safety fences for playgrounds

It is common for playgrounds to be located near roads, so it is necessary to extreme caution to protect children while they enjoy themselves, and at the same time, to increase the easiness of their parents.

When children playgrounds are sorrounded by road traffic areas, some solution based on fences should be adopted. In addition, these security fences prevent dogs or cats from entering the children's enclosure, which if not supervised, can be dangerous for the little ones.

The correct installation of the safety fence for playgrounds is essential, otherwise it could become another element of risk.

Safety requirements for fences for playgrounds

Security fences are an active security element, hence they must meet certain requirements to be 100% effective:

  • Recommended minimum height of the fence 80 cm from ground level.
  • Make sure it does not have sharp or protruding elements.
  • Avoid shapes that can cause entrapment.
  • Any edge must be smooth, never sharp.
  • Fences must be installed at a minimum distance of 2 meters from the playground.

In addition to this, it is also important to ensure that the installation of the park fence is executed correctly. If the security fence is installed on sand or earth, it is recommended to anchor it on a concrete foundation, using anchor plates with holes.

Here there are some examples, but from Metalesa we take care of adjusting the needs and requirements of the project in a personalized way.

Security fences for schools

Unlike playgrounds, in schools parents are not present to watch over their children. Teachers are responsible for ensuring the safety of hundreds of children, but personalized surveillance is impossible, therefore, it is necessary to install security fences for schools.

The entire school should be sorrounded with fences, either short ones if little children or much higher for older. Each case must be studied personalized taking into account potential risks and students profile.

Now is the perfect time to remodel security fences in schools to face new school year in September.

Types of security fences for schools and playgrounds

At Metalesa we have a wide range of fences for schools and playgrounds. They all guarantee great durability, low maintenance and most importantly, they comply with all the safety guarantees for the little ones.


Metal fences

Our metal fences for schools can be of various kinds and shapes, and are specially designed to guarantee protection or close any type of enclosure, in this case school zones.

They delimit the space in an effective way, preventing children from leaving the premises during school hours.

Fences and enclosures

These types of fences are used to close those areas in which some type of security breach may occur. In this sense, they are not only used to prevent children from leaving school areas, but also to limit access to people outside the school, especially at night, guaranteeing both the protection of people and the facilities of the campus.

We have several models, but we can manufacture custom designs requested by our clients.

Steel railings

Steel fences for schools and playgrounds are other ideal containment system to ensure the safety of the little ones. They are easily installed and can be customized them in the color that is needed in order to integrate with the aesthetics of the area.

Stainless steel railings

The aesthetic finish of the stainless steel railings makes them ideal for any type of urban area, such as playgrounds. In our catalog we have available to our clients a wide variety of unique and attractive designs that adapt to all types of environment.

At Metalesa, we care about guaranteeing Road Safety in all senses, and without a doubt, children are one of the groups we pay the most attention to. In addition to designing, manufacturing and installing safety fences for playgrounds and schools, we also consider that it is essential to promote Road Safety education for the little ones, because in this way we will reduce the risk of serious events occurring in this type of enclosure.

How to avoid noise in leisure premises

When we hear the term ‘noise pollution’, it is commonly associated it with the noise produced on the roads due to traffic, industrial zones… But these activities are not the only ones that generate excess of noise.

In this sense, entertainment venues such as restaurants, bars, nightclubs, game rooms ... are also a source of noise to take into account if we want to guarantee the quality of life of people who live in areas close to this type of premises. .

In the entertainment venues several factors are mixed, on the one hand, music is usually very loud, and on the other hand, the bustle of people outside. All this together leads to an acoustic problem in cities to which Metalesa aspires to provide a solution.


Acoustic regulations for leisure venues

Leisure venues are obliged not to exceed certain noise limits. In accordance with Law 7/2002, which refers to protection against noise pollution, and many other regional or local legislation, these are the maximum acoustic levels allowed in this type of premises:

  • Nightclubs: 104 dB (A)
  • Venues with musical ambience: 90 dB (A)
  • Game rooms: 85 dB (A)
  • Bars and restaurants: 80 dB (A)

However, it is important to add that, although an entertainment venue may be complying with acoustic regulations, noise can still be annoying for people living in its surroundings, specially at night.

For this reason, it is so important to provide these businesses with the accurante infrastructures to eliminate noise pollution, preferably through acoustic screens specially designed for leisure venues.

First step: carrying out an acoustic study in leisure venues

The first step is usuarlly to carry out an acoustic study in the area affected by excessive noise.

Experts in acoustic studies use both measurement equipment and a very clear methodology. They are responsible for evaluating it there is an actual excesso of noise over the limits established by law. The acoustic study duration may bary from a few hours to several days, depending on various factors, for example, if it is a closed or an open room, or if it is a high or low space.

A noise map is obtained as a result of the acoustic study. If the indicators show that the actual noise surpasses the legal limits, METALESA can handle the solution with its accoustic screes. Later one, the experts will return to confirm that the original acoustic problem has disappeared.

In fact, it is important to bear in mind that conducting an acoustic study is mandatory for all those premises that produce noise with a sound pressure level greater than 70dBA. The specifications of each premises are included in the municipal ordinances.


Types of acoustic screens for entertainment venues


Urban acoustic screen for leisure venues

Urban acoustic screens for entertainment venues are ideal for outdoor terraces. In addition to being effective, they also fulfill an aesthetic function.

At Metalesa we design, manufacture and install urban acoustic screens for leisure venues of three types: metal, methacrylate and wood. All types of acoustic panels will be equally efficient, but aesthetically one type of acoustic screen may be more convenient than another.

For example, transparent methacrylate acoustic screens are perfect to attenuate noise while customers do not lose attractive views. On the contrary, if it is a space where privacy is important, it might be a better idea to chose metal or wooden acoustic screens. In addition, this type of acoustic screens can give entertainment venues their own style and personality.

Acoustic screen with vegetal mesh for leisure venues

The Metagreen acoustic screen is also an acoustic barrier that provides a great solution to the aesthetic appearance. A leisure space that surrounds its area with this type of screen will create a vertical garden that will act as a decorative element of the walls of the premise.

The growth of vegetation in this type of acoustic panels is achieved by adding over the rock wool a green plastic mesh that facilitates the growth and rooting of vegetation on both sides.

Design Acoustic Screen

For us, each client is unique and that is why we attend to their needs in a totally personalized way. The quality of our products consists of offering the client a product that is 100% adapted to their projects.

Successful entertainment venues tend to have a well-defined and studied design and decoration, and the installation of an acoustic screen should not be a disruptive element in this harmony. Our Design Acoustic Screens allow the owners of the entertainment venues to never lose their style, and at the same time comply with the acoustic regulations.

As we have previously mentioned, at Metalesa we take care of offering a quality product that not only meets high expectations in relation to acoustic problems, but also at the level of design and adaptation to the space of our clients.

The truth is that it cannot be denied that the installation of acoustic screens for leisure venues is always a good idea to guarantee the rest of the neighbors and avoid more than one complaint on their part, improving the image of your premises.

If you are the owner of a leisure establishment, do not hesitate to contact us. It is not worth risking a possible fine, or generating discontent in your neighborhood. Bet on the safety, health and aesthetics that our acoustic screens guarantee. To request a quote, call us at 96 088 99 44 or send us an email to

The loudest roads and railway areas of the Valencian Community

It is no secret that both roads and railways are sources of excessive noise, causing annoyance both to the population and to the conservation of the environment. Specifically in the Valencian Community, it is estimated that approximately 183,000 inhabitants are daily exposed to noise that comes from the main infrastructures, which is a quite alarming fact considering the negative consequences of noise pollution.


The CV-35, one of the roads with the highest levels of noise pollution


The acoustic studies carried out in the main roads of the Valencian Community have concluded that the CV-35 is one of the most affected road, since around 10,000 people support up to 75 decibels at peak times of the day.

Another section with a high noise concentration is the one between Vilamarxant and Benisanó on the CV-50. In this area there are several schools and institutes that must withstand noises of up to 70 decibels.

On the other hand, although the railway network generates less acoustic nuisance, we must also focus on the acoustic problems that derive from the noise of the trains.

According to a European Environment Agency (EEA) report in 2010, railway noise affected over 12 million inhabitants of the European Union every day, figures that may well have increased since that time.

Rail noise in Europe is especially concentrated in Western European countries, among which is Spain. The main sources of noise pollution in railways are engine, rolling and aerodynamic noise, while the most annoying ones are produced by freight trains. We must not forget that passenger stations, places for receiving goods (dry ports), train maintenance activities and other facilities also generate noise in their daily operation. Given this, it may seem that noise pollution caused by the railway and its facilities is almost impossible to eliminate, but the truth is that it is easier to mitigate.

Consequences of noise pollution for our health

As we have seen, there are high figures that confirm that many people are victims of the problems derived by noise pollution from roads and railway areas in the Valencian Community. What are the harmful consequences of excess noise for health?

  • Hearing problems: it is the most common and one of the most worrisome. Keep in mind that any sound above 85 decibels can damage hearing, and on roads and railways, this limit is often far exceeded. Someone who lives in this type of area is continuously exposed to a very high noise level, and consequently can develop hearing loss.
  • Cardiovascular problems: Constant exposure to high noise levels can increase blood pressure, increase heart rate and increase stress by releasing the hormone cortisol ... All of this can lead to an imbalance of vital body functions.
  • Sleep problems: If the home is near highway areas, the noise from freight trucks is very likely to cause sleep disturbances. As we mentioned in the previous point, cardiovascular problems are a long-term effect of this exposure to excess noise. In the short term, the most notable are fatigue, impaired memory and creative abilities, and difficulty concentrating.
  • Digestive problems: Although to a lesser extent, there are studies that have shown that excess noise leads to a decrease in peristalsis, that is, muscle contractions thanks to which the food eaten moves through the digestive system. As a consequence, problems such as gastritis, ulcers, heartburn, loss of appetite, diarrhea or constipation may be more frequent.

How can we solve this problem?

The expansion of urban centers towards industrial areas has meant that many living areas are located very close to road and railway infrastructures, and this requires effective solutions that eliminate excess of noise.

Acoustic Screens

As experts in acoustic solutions, from Metalesa we can certify that acoustic screens are an effective solution to reduce or eliminate this noise. But first, from Metalesa we get in charge of conducting acoustic studies, which are used to extract noise maps that measure noise pollution in a specific area, and based on the results, we take care of adopting the necessary measures through the installation of acoustic screens.


Types of acoustic screens for roads and railway areas


Steel or aluminium metal acoustic screen

These types of acoustic screens are made up of galvanized steel or aluminum panels, which are vertically superimposed between HEA / HEB profiles until the desired height is achieved. By installing metal acoustic screens on roads or railway areas close to human environments, we obtain maximum insulation and absorption, which is a very effective solution to counteract the negative effects of noise.

In addition, other advantages of the metallic acoustic screen are its ease of installation, its long durability thanks to the quality of its components, and its resistance to loads such as the action of the wind or the overpressures produced by rail traffic.

Metallic acoustic screen with mesh or vegetable

This type of plant acoustic noise screens also achieve great noise absorption and acoustic insulation in road and railway areas. Inside the panels that form it, rock wool is placed together with a green plastic mesh that facilitates the growth of vegetation.

Methacrylate acoustic screen

Las características acústicas de las pantallas acústicas de metacrilato o vidrio también son muy eficientes. Están formadas por paneles de metacrilato cuyas propiedades de aislamiento han sido evaluadas de acuerdo a la norma EN 1793-2:1998, obteniendo un elevado índice de aislamiento.

The acoustic characteristics of methacrylate or glass acoustic screens are also very efficient. They are made of methacrylate panels whose insulation properties have been evaluated according to the EN 1793-2: 1998 standard, obtaining a high insulation index.

In addition, it is an easy-to-install acoustic screen, which allows landscape integration, and has a long durability thanks to the quality of its components. For all this, they are ideal to be installed in noisy areas.

Methacrylate can be transparent or have a certain color. Likewise, it is possible to install vinyl solutions on the methacrylate to prevent damage to the birds in the environment.

Wooden Acoustic Screen

This wooden anti-noise screen performs a double acoustic and aesthetic function and is made up of the following elements:

  • Absorbent and reflective face: treated Scots pine wood slats.
  • Acoustic insulation: rock wool with black protective veil.
  • Supporting structure: made up of HEA / HEB-type uprights with hot-dip galvanized welded base plate and painted with polyester powder paint.

Concrete acoustic screen

Concrete acoustic screens are also a very effective option for noise abatement in railway areas.

Among its main characteristics we find its great stability, and its resistance over time, which is why its maintenance is scarce. This consistency is achieved thanks to its materials: cement, sand, water and gravel or crushed stone, giving rise to a highly rigid structure.

The concrete is supported by metal pillars, which also receive a specific treatment to withstand the passage of time. The anchoring of the steel profiles is carried out on the concrete through bolts of variable diameter and length, depending on the client's needs.

Like the rest of acoustic screens, it also allows maximum noise absorption and excellent landscape integration.Noise pollution is a very serious problem, but ‘invisible’ and fortunately more and more society is giving it the importance it requires to implement effective solutions. Undoubtedly, the installation of acoustic screens to absorb noise on roads and railways is the best option to prevent harmful consequences on the health of people who live near these areas. At Metalesa, we want to be part of the solution with our acoustic screens. If you need our services, contact us by calling +34 96 088 99 44 or send us an email to

scooters para la movilidad urbana

How has mobility in cities changed?

Mobility through cities is becoming more and more “à la carte” while ways of transport are increasingly modernizing, thus adapting to the needs of different profiles of people. We see how every day companies offer mobility solutions for cities that adapt their services to the comfort and personalization that citizens are demanding, making them more ergonomic, economical and trying to be as respectful as possible with the environment.

The importance of adapting

Currently we want to move faster, save time, and if possible, with the lowest energy consumption and the lowest economic cost. The proliferation of geolocation technology has enabled the use of applications that help us to know real time the arrival of the bus at our stop or how the traffic is in the city. Many cities, in their quest to become smart and sustainable, have established new urban solutions to improve the use of public transport, and have limited traffic in some areas, even prohibiting the circulation of private cars in downtown areas with a high concentration of users.

This trend has materialized in the deployment of solutions such as bollards or bike lanes, the adaptation of all horizontal and vertical signs, and the offer of subsidies for the purchase of personal mobility vehicles. The response of the citizens has not waited long, and thus we have seen massive purchase of bicycles and / or electric scooters, not only in large cities, but also in smaller towns. Little by little, all these measures integratede into comprehensive sustainable urban mobility plans are working together to create pollution-free urban areas.

In a society that is increasingly aware of the importance of caring for the environment, and willing to adapt itself to the new times, it has been inevitable that this type of electric personal mobility is in fashion and that it is expected to continue growing. At the same time, this has acted as a catalyst for the industry to innovate and bring new mobility solutions to market.

This set of chained consequences lead our cities into a virtuous circle that reinforces investment in safe urban mobility, either with solutions such as bollards, or with other types of parapets, guardrails or urban containment barriers. In short, minimizing the risk for pedestrians, cyclists, or those who lean towards the electric scooter.

Our urban mobility solutions 

Our commitment to society lays on our purpose of saving lives. This has led Metalesa to work for a long time to improve people’s lives. Urban solutions to bring an improved safety for citizens in their daily urban mobility, is a key area where we have been concentrating our efforts in recent years. Some of our most demanded products to improve mobility in cities are urban parapets, cyclopedestrian railings and bollards

  • The urban parapet, which Metalesa manufactures and installs, is a containment system designed to be installed on urban roads or with a limitation of up to 20, 30 or 50km/h. Manufactured for its perfect integration in the urban areas such as streets, avenues or roundabouts.

  • As for the cyclopedestrian railings, we have a wide variety of models capable of adapting to the road infrastructures of any city. It is an urban containment system in order to protect both pedestrians and cyclists who pass through the bike lane from road traffic.

  • We also have a wide variety of bollards. Its main objective is to delimit vehicle access to pedestrian, cycling, or leisure areas. To this day, it continues to be a safe bet for the improvement of mobility in cities. We have also carried out a number of installations in private areas of industries or logistics centers.

If you want to put an end to these problems and want a smart solution, don’t hesitate to contact us. Our service of technicians and advisers of the commercial department will not hesitate to offer you a proposal that adjusts to your reality so that our service is 100% effective.

World Environmental Education Day

Every January 26th we celebrate the World Environmental Education Day. Obviously, it is not a day of celebration but of awareness instead. As a society we have taken some steps to preserve the environment, but we still have a long way ahead.

On this very necessary day, we seek to sensitize society about the relationship between human development and the conservation of the planet. There two phenomena must go hand by hand, supporting each other and not in opposition as it used to happen a few decades ago. At Metalesa we believe that it is necessary to stop and reflect on this, because we care about people and improving their quality of life.

Origin of World Environmental Education Day

Let’s start by giving context to this article with a little background on World Environmental Education Day.

It has its origin in 1975, the year in which the International Seminar on Environmental Education was held in Belgrade (Serbia). At that event experts from over 70 countries participated and established the principles of Environmental Education within the framework of the United Nations programs. As a result of this milestone, known as the Belgrade Charter, the fundamental demands of Environmental Education were reflected.

Since then, every January 26th, all countries use this day to promote awareness-raising initiatives on regards for the Environment. Specifically, in Spain, the Environmental Documentation and Information Section of the CENEAM (National Center for Environmental Education) produces each year a guide to fundamental resources for environmental education, very useful to begin studying, deepening and investigating, and a basis on which to launch a series of environmental education programs and activities.

Objectives of environmental education

In general terms, Environmental Education aims to achieve the following goals:

  • Awareness: Help people, both individually and collectively, acquire greater sensitivity about the importance of caring for the environment.
  • Knowledge: To take care of the environment, you need to know how to do it. The population needs a basic understanding of what it means to be responsible for our environment and the resources we consume.
  • Attitudes: It is essential to acquire values ​​and promote interest in actively participating and protecting the environment.
  • Evaluation capacity: Help social groups to evaluate the measures of environmental education programs.
  • Participation: Help people develop their sense of responsibility by actively participating in this common goal.


Technology and Environment: an essential tandem

Human development understands that the people of a society can develop their maximum potential and lead a productive life according to their needs and interests. The increase in population, the increase in energy expenditure, the increase in the productive capacity of food … all this is very good, but we cannot ignore the fact that it also leads to environmental effects such as pollution, massive cutting of trees, depletion of water resources or global warming.

The mastery of technology to social evolution has meant that, in many situations, this development accelerates these negative consequences. However, it is also true that our actions, and how we use technology, may be part of the solution. But how can technology help reverse them?


Benefits of technology at the service of the Environment

Let’s see some examples of how technology contributes if we propose to improve the environment:

  • Recycling: increase the volume of recycling and the efficiency of the recycling process of different activities and materials.
  • Design of cities based on Smart Cities models: design of smart cities that satisfy the needs of the population with an optimization of the use of resources. We tell you more about Smart Cities by clicking on this link.
  • Development of new forms of energy: friendly to the Environment such as wind or solar energy.
  • Development of sustainable means of transport: fuel that respects the environment, such as cars or electric motorcycles.

This list could be very long, as long as the will of the whole of society wants it, because as we have said, an adequate use of technologies can have a positive impact on the protection of the Environment.


Our commitment to the environment

Every company should take into account its environmental footprint, that is, the impact generated by the service or product it offers.

At Metalesa we have always been aware of this. We know that as a company we must provide solutions and be innovative to satisfy one of the priority demands of society: the commitment to the environment and sustainability.

We achieve this task from different initiatives:

Installation of Thermo-lacquering and Zero Discharge Treatment Plant

Many of our products, for example our steel or aluminium acoustic screens, go through the thermo-lacquering process if the customer requires it. The process consists of applying a powder coating to a piece of metal that has been prepared, previously treated, and then cured in the polymerization oven.

Powder coating process is very respectful with the environment as it is a clean coating. The powder paint we use does not contain solvents, and the powder that does not adhere to the part is recovered for reuse. This use of almost 98% represents a reduction in the amount of waste generated.

Regarding the zero discharge treatment plant, it is a technology that we use in our facilities in order to control waste and acquire a commitment to continuous improvement with sustainability. The zero discharge treatment plant allows us to contribute to the recovery of aquifers, since it allows us to reuse water in all our industrial processes through a cleaning process by electrolysis. in this way we manage to minimize the amount of water used and we manage to optimize all our resources.

Other initiatives in our facilities that favor sustainability

  • Photovoltaic installation: At the end of 2020 we have installed a photovoltaic solar plant of up to 100KW of power on the roof of our factory. Technical studies estimate that with this installation we will produce up to 60% of the energy we consume per year in the development of our operations.
  • Replacement of LED luminaires: In all the facilities of our factory we have installed LED lights, with this change we manage to reduce annual energy consumption by up to 15%.
  • Replacing diesel trucks with electric trucks: For a long time all our trucks have been electric, therefore they do not produce CO2 emissions.
  • We encourage the use of 0 paper: We try to spend as little paper as possible, and we achieve this thanks to the digitization process we are carrying out. We have managed to reduce the use of paper by up to 75%.
  • Installation of EV charging points:  This is one of the initiatives we have planned. We want to make different charging points for electric vehicles available to our employees throughout our facilities.
  • Compliance with environmental standards and guidelines: Through our sustainable commitment, our intention is to achieve official accreditation of standards related to the Environment such as: Standards for Energy Efficiency Management Systems ISO 50001 or Carbon Footprint ISO 14067.

Our products: Acoustic Screens

One of our main products are acoustic screens, barriers specially designed to reduce a problem so harmful to people and animals, noise pollution. At Metalesa we manufacture all kinds of acoustic screens that fulfill their anti-noise function, but we have three models that are especially beneficial for our environment:

Metagreen Acoustic Screen

Rock wool is placed inside the plant screens, which, together with a green plastic mesh, facilitates the growth of vegetation in the style of a vine, generating in a few months a green acoustic wall, optimally integrated into the environment.

Bird Collision Screen

These types of acoustic screens are specially designed to prevent birds from colliding with vehicles or trains traveling on the tracks. This is how we achieve their preservation and protection of their migration routes.

Screens for wildlife passage

Screens for wildlife crossing are installed in overpasses equipped to protect the passage of fauna and livestock that circulate over roads or railroad tracks. These are wooden panels that are supplied with a chemical treatment that guarantees the preventive and curative action of insects and fungi, as well as solar radiation. Furthermore, the wooden panels optimize their integration into the environment.

To conclude, we will return to the task of World Environmental Education Day. To advance as a society, it is necessary to appreciate the Environment, and it is everyone’s responsibility to learn and internalize correct behaviors about it. Nature is not an inexhaustible source of resources, so we must all put our best efforts together to try to make our actions as less harmful as possible. From Metalesa we have already joined this objective. And you?

Safety in urban areas and on the cycling lanes

As experts in Road Safety, one of our tasks should be to promote greater awareness about the safety of people, both in urban areas and on roads. In this sense, although our products are intended to make people’s lives safer, at Metalesa we intend to go further and we want to do our bit in this ongoing process of awareness.

In today’s post we talk about the safety of cyclists when they circulate through urban areas or roads. Undoubtedly, it is one of the most vulnerable groups that suffer too many accidents, which is a problem that must be solved.

To start with, here there are some figures. In 2014, 75 cyclists died on Spanish roads, in 2015 there were 55 and in 2016 it was reduced to 33. Having said that, although the trend of cyclist accidents seemed to be decreasing in the last five years, the truth is that in May 2017, these figures were already doubled, and in 2020, 36 cyclists lost their lives, a surprising number after long months of confinement.

At the beginning of the article we mentioned that our products are intended to ensure safety. However, people must also do their part to achieve this goal. Here there are some useful tips for both cyclists and drivers to ensure the safety of those both in urban areas and on roads.

Everything a cyclist needs to know to ensure their safety

Although there may be external factors that endanger their safety, it is important that the riders know how to protect themselves:

  • To know traffic regulations, and therefore, what you can do and what it is forbidden on the road will allow them to be more aware of the dangers.
  • If there is no bike lane on the road, it is preferable to travel on roads with a wide shoulder, much better if they are little traveled.
  • The use of conspicuous clothing is recommended to make themselves more visible. Here we also include the helmet color, which is mandatory.
  • Check wheels, brakes and lights from time to time. Something as fast as a simple check-up can save a rider’s life. Regarding the lights, it is important to note that they should be used both at the front and at the rear in low light hours. In addition, it is mandatory to turn on the lights when driving through the interior of a tunnel, whatever time it is.
  • Use of the rear-view mirror. This device is less common than it should be. Rather few cyclists decide to attach a rear-view mirror to their bicycle, but it is undoubtedly a very useful component to increase safety, and cheap indeed.

What must a vehicle driver take into account to ensure the safety of cyclist?

  • It is important to bear in mind that, when passing a cyclist, the air displaced by the vehicle can throw him off balance. Therefore, when overtaking, at least 1.5m of lateral space must be left as a safety distance.
  • If cyclists are observed, slow down and be extremely cautious.
  • The horn should not be used to warn the cyclist of the presence of the vehicle because it can scare, distract and cause them a fall.
  • It is very important to know when cyclists have priority. For example, a group of cyclists has priority when they have started a crossing or entered a roundabout.
  • Only with greater respect for the priority of passage and the safety distance could the number of cyclist victims be significantly reduced.

We are aware that these are quite obvious pieces of advice, but it is not a bad thing to remember them considering that, statistically, most accidents occur precisely because of not complying with these simple tips.


Road Safety Improvements for cyclists through urban planning

Not only are people becoming more and more aware, so are cities, orienting their planning towards more efficient models, both in terms of safety and sustainability. In this sense, the promotion of urban mobility through the use of bicycles entails an ambitious urban reorganization that involves the implementation of cycle lanes. In fact, we are seeing that the cities deploy every day more kilometers of bike lanes.


How do we guarantee the safety of cyclists from Metalesa?

Protection is our goal. That is why we design and manufacture road safety products specially designed for this.

Our M009 cyclopedestrian railing is a restraint system for cyclists that cannot be absent in urban areas or on roads to reduce the accident rate of cyclists.

It is located at the ends of bridges or crowning walls to prevent pedestrians and cyclists from falling into the void. It differs from a normal railing in its height, between 1.3 – 1.5 meters, which prevents cyclists from exceeding it, which is perfectly possible with traditional railings for pedestrians up to 1 meter high.

In addition, all the components of the railing are protected against corrosion by individual or duplex coating, at the customer’s discretion: hot galvanized, thermo-lacquered or both treatments at the same time.

The thermo-lacquering allows to facilitate the aesthetic integration of the cyclopedestrian railings with the environment, since we can paint them in any color from the RAL chart.

In a previous post we made reference to how 5G technology in cities can help ensure maximum safety. Perhaps a day will come when cyclists will cease to be a vulnerable group thanks to the development of tools based on wireless connectivity. However, at Metalesa, we obviously support technological progress and the great advances that it can bring to road safety, but we also want to take advantage of it to call for the responsibility of each one. Safety is everyone’s business!

En un post anterior hicimos referencia a cómo la tecnología 5G en las ciudades podrá ayudar a garantizar la seguridad al máximo. Quizá llegará algún día en el que los ciclistas dejen de ser un grupo vulnerable gracias al desarrollo de herramientas basadas en la conectividad inalámbrica. No obstante, desde Metalesa, evidentemente apoyamos el progreso tecnológico y los grandes avances que puede aportar a la seguridad vial, pero también queremos aprovechar para hacer un llamamiento a la responsabilidad de cada uno. ¡La seguridad es cosa de todos!
