Wall cladding panel MG2-T

The MG2-T sound-absorbing wall or tunnel cladding consists of ribbed steel or aluminium panels that are perforated on one side, with rock wool inside them.

Its field of application is specific for installation as a solution to sources of acoustic pollution from road and rail traffic inside and outside tunnels or on underpasses or walls.

Panel Morphology

  • Material: STEEL
  • Is it absorbent for both sides?:
  • Assembly: SELF-TAPPING


  • Panel: made with ribbed and galvanised steel plate. At the customer’s request, it can include a powder coated finish in different colours of the RAL chart to provide excellent resistance to its outdoor location.
  • Rock wool: with protective facing on the side exposed to the perforated side
  • Fixing system: wall anchoring system that uses adjustable rods composed of profiles so that the panels can adapt to straight or irregular walls.
  • Metal rivets: upper and lower steel or aluminium rivets. They adapt to the morphology of the facing to guarantee the alignment of the panels.


– Panel configuration provides maximum absorption.

– Its appearance means it blends in perfectly with the landscape.

– Its varied designs result to different combinations.

– Thanks to its modular structure and lightness, the panel is easy to install.

Long-lasting thanks to the quality of its components.

– Panel for road and rail infrastructure applications.

Powder coating in the different standard colours of the RAL chart.

Acoustic and mechanical features

  • The metal covering provides an acoustic function thanks to its great sound absorption indexes (A3)
  • The simplicity and fixture of the system make it easy to repair and replace if damaged in accidents.
  • Non-flammable covering (class 3 according to Standard 1794-2)
  • Stable structure with vertically arranged panels that provide structural stability when attached to an appropriate support.
  • It improves the appearance of walls and tunnels by applying colour to their surface.
  • It helps in the lighting and visibility of enclosed spaces by reflecting light, compared to the darkness of the usual concrete walls.


Wall anchoring system that uses adjustable rods formed by horizontal guide profiles so that the panels can adapt to straight, curved walls and the irregularities of the treated surface (pile wall, sprayed concrete wall, etc.).

All aspects affecting the final effectiveness of the covering should be considered.
