Metal acoustic barriers

Metal acoustic barriers

Metal acoustic barriers are specially designed to absorb road and railway noise. They are made of steel and aluminum.

Sandwich panels consist of two layers. One is a perforated surface responsible for sound absorption and reflecting the smooth side. Inside the sandwich panel itself there is stone wool, and its thickness depends on the sound insulation requirements of a particular object.

The panels are resistant to gusts of wind. Their big advantage is simple and fast installation.

The structure of load-bearing panels usually consists of steel beams and a reinforced anchor plate.

At the last stage of production, they go through the processes of thermal varnishing and anti-corrosion treatment, which increases their resistance to adverse weather conditions.
