Corten Steel
Introduce
COR-TEN steels, also named as weathering steel, corten steel, is a group of alloy steel which can form a stable rust-like appearance if exposed to the weather. This dense and tight layer of rust appearance will prevent the corten steel materials from further corrosion.
With the addition of alloy elements like Cu, Ni, Cr, Corten steel materials have excellent character of anti-corrosion, and also have advantages in ductility, molding, cutting, welding, heat-resistance and abrasion resistance.
Specification
AHL CORTEN can produce weathering steel products in plates, coils, pipes and sections according to EN, JIS and ASTM standard. With large range of available sizes, AHL-CORTEN steel is a perfect choice for pursuing modern and rustic style.
Here the following are some of the common corten steel plate grades, there are also some other grades known by the high quality of the anti-corrosion ability and their excellent appearance after rusted. Such as 09CuPCrNi-A according to TB 1979.
Service: pre-rusted treatment, bending, cutting, welding, profiling, punching and designing as the requirement.
