Components made of 6 mm thick Corten steel sheet. Corten steel, patented in the 1930s, has the particularity of presenting a protective patina that is created on the surface and gives it its characteristic “rust colour”. This patina protects the steel over time, giving it high resistance to corrosion and atmospheric agents, a characteristic that makes this type of material perfect for outdoor architectural applications. It is advisable to use Corten only outdoors, as it is a “living” material and the external patina that may fall to the ground could stain the materials in close contact with the components made in this finish.
