Concrete Acoustic Barriers
Noise protection systems
INSAMETAL designs, supplies and installs sound-absorbing concrete acoustic panels for railway and highway infraestructures to alleviate external noise.
They consist of a sound-absorbing element, whose main function is to provide the acoustic performance, and the supporting structure, whose purpose is to support the transmission of wind loads and to handle stresses that the element must withstand during its service life. These panels comply with the highest acoustic classification on the market: A3-B3.
TREATMENTS: Hot-dip galvanized according to UNE EN ISO 1461 Thermo-lacquered according to UNE EN 15773
