Weathering Steel Coil

Weathering steel is a steel that is resistant to corrosion but not to rust. This steel alloy is widely used for landscaping and other outdoor applications as it forms a protective layer of rust after approximately six months of exposure to moisture and oxygen. As the rust layer (copper green) protects the steel from further corrosion, there is no need for painting or additional weatherproofing.

Product Description of Weathering Steel Coil

Weathering steel, i.e. atmospheric corrosion-resistant steel(Corten Steel), is a series of low-alloy steel between ordinary steel and stainless steel. Weathering steel is made of ordinary carbon steel with a small amount of corrosion-resistant elements such as copper and nickel. It has the characteristics of toughness, plasticity, forming, welding and cutting, abrasion, high temperature and fatigue resistance of high-quality steel. The weathering resistance is 2-8 times of ordinary carbon steel and the coating performance is 1.5-10 times of ordinary carbon steel. At the same time, it has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving. Weathering steel is mainly used in railway, vehicle, bridge, tower, photovoltaic, high-speed engineering and other steel structures exposed to the atmosphere for a long time. It is used to manufacture containers, railway vehicles, oil derricks, seaport buildings, oil production platforms and containers containing hydrogen sulfide corrosive medium in chemical and petroleum equipme.
