Corten A Steel Sheets Products Details

The atmospheric corrosion resistance of Corten-A is due to the formation of a dense layer of rust on the surface of the steel, the steel matrix is isolated from the air and effectively prevent the continued growth of rust. special elements contained in COR-TEN, in contact with the atmosphere, the formation of a layer of oxides film, this layer of solid film so that the COR-TEN in the outside world is isolated from the influence of the climate, and to achieve the purpose of weathering and corrosion resistance. When Corten-A or ordinary steel is exposed to the atmosphere, chemical reactions occur when it comes into contact with moisture and oxygen.

Corten-A weathering steel is made by adding a little copper, chromium, phosphorus and other elements to ordinary steel, and through special treatment, its weathering and corrosion resistance is three to eight times higher than that of ordinary steel. Depending on the type and application, CortenA can be categorized into four types: COR-TEN A, COR-TEN B, COR-TEN C, and COR-TENB-QT. Among them, COR-TEN A’s weathering and corrosion resistance is five to eight times better than that of ordinary steel, while COR-TEN B’s is four times better.
