METALESA SEGURIDAD VIAL manufactures, supplies and installs different types of acoustic panels and screens to protect against noise pollution from lineal infrastructures (roads and railways).
The metal screens are made from galvanised steel or aluminium make up an enclosure with internal acoustic absorption. The panels overlap vertically between HEA/HEB profiles until the desired height is reached.
Each metal panel adapts to different profile widths.
We have available a wide range of steel and aluminium metal panels with differing characteristics certified by accredited laboratories. The wide range of solutions allows an appropriate response to almost all current projects.

The panels are mechanically tested based on Standard EN 1794-1 and showed they can support very high loads in tests performed in accredited laboratories.
For certain solutions, there is the possibility of guaranteeing the mechanical properties through appropriate analytical calculations as provided for in current regulations.
– Maximum insulation and absorption is obtained due to the configuration of the panel.
– The aesthetics provide an excellent integration into the landscape.
– The varied designs provide different combinations.
– The panels are easy to install due to their light and modular structure.
– Long durability due to the quality of its components.
– Panel for use in road and railway infrastructures.
– Strong resistant performance against loads due to wind and excess pressures caused by railway traffic.
– Thermo-coated using the RAL colour standard.
ANCHORING
Anchoring the profiles to the foundation is by means of varying diameter and length bolts according to the specific requirements of each project.
FOUNDATIONS
The foundation provides structural stability to the screen, formed of the pillars and acoustic panels, and must also ensure the stability of the surrounding ground.
Types of ground foundation are:
The panels are supported by HEB or HEA steel beams anchored to a foundation that must be calculated based on a study of the terrain, wind resistance, etc.
Steel profiles are used to fasten the panels to the beams, which are anchored to both the panel and the profile.
Aspects having an impact on the screen’s final effectiveness must be considered as a whole: compliance with on-site construction conditions, installation of the screen, type of panel, distance between beams, etc.
Equally as important as the panels’ characteristics are suitability of the type, height, insulation parameters, acoustic simulation, etc. It is also necessary to carry out adequate foundations to guarantee the system’s stability. Our engineers and calculation engineers jointly manage all these factors to ensure the screen functions properly.
At the client’s request, we carry out the entire assembly process:
– Foundation calculations and bearing structure.
– Staking based on topographic elevation.
– Execution of foundations.
– Assembly of support profiles and placement of panels.
Our engineering team has extensive calculation and optimisation experience, and our team of assemblers and associated subcontractors have spent years assembling acoustic screens in all conditions.
