The galvanised steel structures manufactured by our company and used for the construction of soil barriers are free-standing, self-supporting steel modules filled with soil and aggregate, constituting a noise barrier used to facilitate direct dispersion of traffic and industrial noise in the air.

Soil barriers are a load-bearing structure, in which the load-bearing components are steel frames set upon a carefully prepared base surface, fixed together by bolts and ties. The complete steel frame is coated on the inside with mats and covered with soil and aggregate.
