Weathering steel is also known as COR-TEN Steel, which is a group of steel alloys that form a stable rust-like appearance after several year's exposures to weather. There are two distinguishable properties from common steel: corrosion resistance and tensile strength.
The surface oxidation of weathering steel takes six months to form a stable rust-like appearance after several year's exposures to weather. This is a protective layer and protects the steel from atmospheric corrosion.
It is widely used in bridges, architectures, outdoor sculptures, towers, oil derrick, vehicles, containers, etc.. Henan Anhuilong Steel can accelerate the oxidation to several hours/several days through surface treatment for the weathering steel/Corten Steel.
