Noise barriers for the motorways

Noise barriers for the Centropadane Motorways.

The noise mitigation campaign for the Centropadane Motorways continues to provide an adequate service to the community.

  The batch of works portrayed in these photographs refer to the installations in “Pometo Sud”, “Paolina Nord”, Bagnolo sud 2 “, Bagnolo sud 1” and “Colombo Nuovo”. Noise barriers, made of steel supporting structure and sound absorbing glass and wood panels, are installed in an environment classified as environmental corrosion class C3. The Centropadane Motorways, after careful evaluation, chose the SISTEMA TRIPLEX anti-corrosion protection for the steel structure. In view of the application and the choice of “yellow” as the colour, known to be one of the most problematic aesthetic pigments, SISTEMA TRIPLEX was realised with “Qualicoat 1”, type coatings which are able to guarantee colour retention for over 10 years.

Noise pollution is one of the factors that most disturb the more populated areas in the vicinity of major road networks, and noise barriers are an intelligent and appreciated solution. The durability of the manufactured products is one of the requirements to maintain the soundproofing parameters effective over time. The use of steel to build the support structure guarantees durability especially if the surface is treated with adequate protection. Wood is a sound absorbing material and, when used with steel, generate an intelligent and environmentally sustainable solution. Once their useful life is over, the materials can be recycled for other uses. Furthermore, the durability of the manufactured product generates a lower consumption of energy for the production of both steel and the transformation of wood into processed timber.
