Weathering Resistant Corten Steel Coil

Weathering steel is also called Corten steel, weather resistant steel, weather-resisting steel, or atmospheric corrosion resisting steel. It forms a protective layer on the surface of the metal matrix by adding corrosion-resistant elements such as copper, chromium, phosphorus, nickel, molybdenum, niobium, vanadium and titanium on the basis of ordinary carbon steel, so as to improve the atmospheric corrosion resistance.

    Weathering steel is also called Corten steel, weather resistant steel, weather-resisting steel, or atmospheric corrosion resisting steel. It is characterized by adding a small amount of Cu, P, Cr, Ni and other alloy anti-corrosion elements to the steel to form a oxide layer of about 50μm~100μm between the rust layer and the base metal. Due to the existence of this dense oxide film, it prevents the infiltration of oxygen and water in the atmosphere into the steel matrix, slows down the in-depth development of corrosion to steel materials, and greatly improves the atmospheric corrosion resistance of steel materials. Without any anti-corrosion treatment, the corrosion resistance of weathering steel is 2.28 to 2.6 times that of common carbon steel. At the same time, the metal components made of Weathering steel/Corten steel have the characteristics of rust and corrosion resistance, thinning and consumption reduction, labor saving and energy saving.

    The Weathering Resistant Corten Steel Coil of Shanghai BISCO International Corporation has perfect impact toughness and cold working performance, with small sensitivity of cold and hot cracks and excellent welding performance; it has high dimension precision, flat plate, and smooth surface and excellent coating performance. If there is a need of this product, please feel free to contact us, we will provide you with a quotation within 24 hours since receiving your inquiry.

    Application

    Weathering steel/Corten steel has the characteristics of toughness, plastic ductility, easy forming, easy welding and cutting, corrosion resistance, high temperature resistance and fatigue resistance. It is mainly used for engineering components exposed to the atmosphere for a long time, such as railways, vehicles, bridges, containers, environmental protection equipment, pylon & tower, photovoltaic and high-speed projects. In recent years, it is also increasingly used in the garden landscape decoration industry, such as rusty sculptures and landscape curtain walls, retaining wall…etc.
