S355K2G1W S355K2G2W Weather Resistant Steel plate
Atmospheric Corrosion Steel Plate Products Description
S355K2G1W atmospheric steel is a high strength weathering steel that complies with the EN 10155 European standard and is suitable for structural steels that require good atmospheric corrosion resistance.
S355K2G2W corten steel metal is a high performance weathering structural steel that is similar to S355K2G1W and complies with the EN 10155 European standard.
S355K2G1W corten steel plate and S355K2G2W corten steel sheet are used in outdoor buildings and structures and exhibit good corrosion resistance without coating, especially in wet or salty environments.
S355K2G1W corten steel sheet metal and S355K2G2W corten steel sheet promote the formation of a surface oxide layer through their specific alloying element content (such as copper, nickel, chromium, etc.), which can provide long-term corrosion protection for the steel.
