S355J2WP steel plate contains alloying elements such as copper, chromium and nickel, and has corrosion resistance. S355J2WP steel is a kind of hot-rolled structural steel with anti-corrosion properties, also known as weathering steel and atmospheric corrosion resistant steel, in line with EN10025-5. The surface of the metal S355J2WP steel plate can form a dark brown oxide layer, which inhibits deeper penetration after atmospheric corrosion. Therefore, S355J2WP steel plate can reduce the cost of painting and the expensive anti-rust maintenance cost for many years.
