How to make a sports complex look new?

All cities, large or small, have one thing in common: their love for sports. Some of them are capable of hosting many facilities, while some others hardly have a sports hall which they know how to get the most out of. A football, basketball, handball or any other sport team can be something iconic for a city, which is partly due to the sports complex where they train and compete in regional, national and international championships. For this reason, it is becoming more important that sports complexes stand out for their structure and design, and thus generate pride and identification among the population.

As you know, since our very beginning, at Metalesa we have dedicated ourselves to ensure the safety and quality of life of what matters most to us: people. Our products are aimed at both road and urban safety and noise reduction. Therefore, we can get in charge that the sports complex of the clubs of a city have the space they deserve.

How do we help?

We reform and modernize sports complexes with the integration of acoustic screens on its façade. This includes:

  • Previous acoustic studies to define parameters to be achieved
  • Aesthetics are important. New screens will provide the facilities a facelift that will not go unnoticed: a quality material, striking colours... sports complexes cannot be left behind in our efforts to modernize cities according to our philosophy of creating Smart Cities.
  • Noise pollution. Sports complexes are usually a big source of noise, usually generated by a passionate public. In addition, many facilities are also used as concert halls. To handle such challenges, our acoustic screens will be a success to guarantee the rest of the close neighbourhood and comply with the regulations on noise pollution in urban environments.

Acoustic Studies

Any project of such scope must be preceded by an acoustic study according to regulations in force. By using advance technologies, we will get as a result the parameters to be achieved, which will act as input requirements to the optimized constructive solution that must meet them. At Metalesa we have extensive experience in conducting these acoustic studies.

What characterize our acoustic screens to be integrated into sport complexes facades?

Minimizing the noise of sports complexes is possible thanks to the characteristics of our acoustic screens made with sound-absorbing panels:


  • Absorbent face oriented to the noise focus: absorbent face is multi-perforated. These perforations make it possible for sound waves to penetrate the panel and dissipate in the absorbent material located inside, thus minimizing noise.
  • Acoustic insulation: as an absorbent material, rock wool of different thicknesses and densities is used depending on the acoustic characteristics that must be met. The rock wool is integrated into the interior of the panels, so that a reduction in the sound level is achieved.
  • Reflective face: The reflective face leaves a space with the rock wool, generating an acoustic chamber, so that the sound waves are reflected back into the absorbent material.
  • Supporting structure: consisting of HEA / HEB type uprights with hot-galvanized welded base plate and thermo lacquered with polyester powder paint. In any case, the supporting structure solution will be adapted to address the particularities and limitations of each project.

Like all our products, metal acoustic screens have been tested under rigorous evaluations to guarantee their acoustic and mechanical behaviour. This evaluation is based on the EN 1793-1 standard, which allows us to obtain the maximum sound absorption and insulation values ​​for the screens we install. Our team of expert engineers and calculators manage all the factors necessary to make the installation of the screens a complete success.

We create and believe in Smart Cities

In the 21st century, our cities are immersed in such a process of technological development, that it is not unreasonable to say that we are already living in what the cities of the future will be. Smart Cities are committed to innovation as a force for change, its aspiration lies in improving the quality of life of its citizens and making a more efficient and sustainable consumption of resources

At Metalesa we have been researching for a long time to develop products and services that have SMART technology, hence we have several projects underway to lead the future market for the 'smart transformation' of transport infrastructures.

What are the features of a Smart City?

  • Collaboration: Not only companies have a voice in Smart Cities, it is about creating collaboration synergies between companies, municipalities, citizens ... we can all contribute to improve the sustainability of our cities!
  • Planning: In a Smart City, decisions must have a reason. What is it missing in my city that would make life easier for people? When facing an opportunity, technological and innovation tools available in the market are analysed to develop product or service.
  • Creativity: Technology, innovation and creativity go hand in hand. This combination allows us to create solutions that make a difference from what has previously been used.
  • Sustainability: It is one of the fundamental legs of Smart Cities. Each contribution to our city must seek for sustainability in the environmental field. The road to Smart Cities is a positive evolution in every way!

In this way, it is not only about innovating, but also a sustainable city must set the objective of achieving efficiency and sustainability through people and technology.

Some conditions to become Smart City

  • To have a social, environmental and economic development based on sustainability criteria.
  • Carry out good management of natural resources.
  • Citizens are committed to the values ​​that characterize a Smart City.
  • Urban infrastructure and equipment are equipped with technology to provide public services that make life easier for citizens.

At Metalesa we create Smart Cities

Not only we create them, but we also believe in them. From our very beginnings, our vision and the values ​​that have characterized us have always prioritized being a leading company, and therefore we are currently very aware of the great opportunities that cities offer us at the level of innovation.

For this reason, all throughout our history we have been able to contribute with our experience to those cities that have needed our services. For example, all our processes are carried out under the philosophy of Industry 4.0, use of technology in all operations of our company.

Our modern containment systems are designed to be incorporated into the future ecosystem of a Smart City, always starting from the basics, guaranteeing road safety. Summing up, the benefits of living in a Smart City are numerous, as they are fuelled by improvements in information and communication technologies which exponentially increase their effectiveness in its service to the citizens.

UNE EN 1317 standard.

What is UNE EN 1317 Standard?

At Metalesa we are very clear about our mission: to ensure the safety of what matters most to us; people. For this reason, we guarantee that our products comply with the established standards and regulations. Seriousness and professionalism is what defines us. Our parapets have been subjected to real tests in accredited laboratories based on the UNE EN 1317 standard.

¿What is UNE EN 1317 standard?

This standard was established on January 1, 2011 by the European Union, and certifies the quality and safety of vehicle containment systems. It is based on subjecting these systems, such as parapets or guardrails, to a test methodology following specific criteria valid for all Europe. Among many other things, the UNE EN 1317 standard harmonizes impact tests simulating real accidents involving vehicles, mannequins as drivers and the containment system itself. In this way, both the behaviour of the system and its impact for the drivers themselves are evaluated.

The configuration of each essay varies completely depending on the level of containment being tested. The type of vehicle involved, the impact speed or the angle of incidence are defined for each essay specifically. After the impact, the damages of the containment system, as well as the deck on which it has been anchored, and the impacto on the mannequins are evaluated. From this analysis the laboratory concludes a set of technical parameters that characterize the behaviour of the system. Main ones are dynamic deflection, working width, severity index and intrusion index.

What is it exactly a containment system?

A vehicle restraint system is a barrier that made of various materials and used to lessen the consequences of an accident on the road. Metallic ones have the advantage of absorbing a large part of the kinetic energy of the crash and facilitate the redirection of the vehicle's trajectory. For this reason, the severity of the impact is lower, thus demonstrating a great contribution to road safety. However, sometimes, the circumstances of the road require a concrete system with less absorption capacity and less deformation. In general, the occupants of the vehicle tend to be more affected. Based on the danger of the sections and on a history of accidents, it is the responsibility of national, regional or municipal public administrations to study and decide where to install or substitute vehicle containment systems.

Parameters to analyze looking at UNE EN 1317 standard

During real tests in an accredited laboratory the following set of parameters are analyzed.

Containment level

It indicates the ability of a SCV to withstand the impact load of a vehicle. The selection of the level of containment that a safety barrier must have proved to be installed on the margins of a road will depend on the risk of accidents, which in turn is defined by the speed of the road and the average intensity of heavy vehicles in each sense at the time of commissioning.

Impact severity

The impact of a vehicle against a SCV carries obvious risks for its occupants. The severity of these risks inside the passenger compartment is determined by the level of impact severity. This is calculated from the combination of the deceleration (ASI) and head impact (THIV) values.

Deformation of the system

The behaviour of a SCV is characterized by the transverse displacement of the device during impact. This is defined in the tests through the parameters of dynamic deflection (D), working width (W) and intrusion index (VI).

On our website we dedicate specific spaces to clarify any questions that may exist about the UNE 1317 standard.

In addition, in our frequently asked questions section on metal parapets we anticipate the queries that we typically receive from engineering or construction companies regarding the interpretation of the standard.

UNE EN 1317 standard applied to our products

Bridge Parapet

Our bridge parapets are metal security barriers that are installed in order to serve as vehicle restraint systems. We market many different models that have success under the appropriate tests to be able to certify the UNE EN 1317 standard, and therefore accredit the CE marking.

On our website you can see the videos of the tests carried out, for example, that of the META16 metal parapet of containment level H3.

We also design, develop and commercialize transitions between containment systems with NF marking after having successfully passed laboratory tests in accordance with the French standard NF 058. It must be taken into account that UNE EN 1317 lacks specificity to evaluate and accredit with CE marking transitions between parapets between each other, or between parapets and other types of barriers.

H2 and H3 parapets, urban and mixed parapets, guardrails ... Those are some of our products in our portfolio whose main purpose is to guarantee road safety.

Handrails and Fences

The handrails and fences that we manufacture and install accomplish high quality standards in order to offer the maximum possible protection both on the road and on urban areas. In addition, they are all subjected to a corrosion protection treatment.

As in the case of bridge parapets, railings and fences are also containment systems that are designed and calculated by our R & D and Structural Calculation departments following parameters set by European regulations. We have a wide variety of these products to accomplish customer demands:

Railings: Steel, stainless steel, with cable and with perforated sheet metal.

Fences: Metallic, anti-vandal and electro-welded.

Thus, it is evident that neither vehicle containment systems can be absent on our roads, nor a norm such as UNE EN 1317, in charge of regulating and guaranteeing their correct compliance. At Metalesa we take road safety very seriously from an efficient and innovative perspective, which leads us to continue growing and betting on the best.
