Product Description for Weathering steel

The COR-TEN steel alloys are high-strength self-passivizing, containing copper, chromium and phosphorus, characterized by high corrosion resistance (cor-rosion) and high yield tensile (ten-sile) strength; these alloys have the property of self-protection through the formation of a superficial coating that prevents progressive spread of corrosion

Weathering steel, best-known under the trademark COR-TEN steel and sometimes written without the hyphen as "Corten steel", is a group of steel alloys which were developed to eliminate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years

Application for Weathering steel The steel is used in a variety of applications, both structural and cosmetic, including bridge construction, structural framework and building facias. Why is Weathering steel better than normal steel?

The advantage of corten steel is that is doesnot have to be painted, it forms a very stable surface rust layer that protects the rest of the materials
