EN S235J2W S355J2WP weather resistant steel
Weathering Alloy Steel Plate Products Description
S235J2W weathered steel plate is a hot rolled steel plate resistant to atmospheric corrosion and complies with the European standard EN 10025-5.
S235J2W corten weathering steel is widely used in bridge construction, building design, wind power generation facilities and other structural projects that require good atmospheric corrosion resistance.
S355J2WP corten steel structure is designed for structural applications exposed to various climatic conditions and can show good corrosion resistance without the need for additional coating protection.
The "WP" in S355J2WP corten structural steel indicates improved weathering resistance and contains alloying elements such as phosphorus and copper to promote the formation of a protective oxide layer on the surface to resist environmental erosion.
