Stainless steel, the material for sustainable development

Stainless steel is the "green material” par excellence and is infinitely recyclable. Within the construction sector, its actual recovery rate is close to 100%. It is environmentally neutral, inert and when in contact with elements such as water it does not leach compounds that might modify their composition.

These qualities make it a material that is ideally suited to such building and construction applications as roofs, facades, rainwater recovery systems, domestic water pipes, swimming pools, bridges and pedestrian bridges, as well as interior decoration. Stainless steel’s longevity fulfills the requirements of sustainable construction. Furthermore, effective selection, installation and low maintenance guarantee the user an unrivaled service life.

Swimming Pool

Our range of stainless steels covers all requirements relating to swimming pool applications: pools (including pool edges, overflow gutters, partitions, etc.), ladders, diving boards, starting platforms and water distribution systems. The grade employed is principally austenitic 316L. For certain applications in harsher environments, such as the thermal spa, one can employ grades with even higher properties, such as duplex DX2205, DX2304.

Bridges and Pedestrian Bridges

Stainless steel can be found in all or any part of a bridge or a pedestrian bridge. Its use is common in elements of protection - handrails and banisters - as well as in the wires on suspension bridges, cables and tie rods. It is also recommended for the deck and for anchor elements, including those built in marine and polluted atmospheres. For these types of atmospheres, the austenitic (304, 316L) or duplex (DX2205, DX2304) grades may be well-suited.
