Atmospheric corrosion resistant EN S355J2WP steel plate is weathering steel. The material number of EN S355J2WP steel is 1.8946. Atmospheric corrosion resistant EN S355J2WP steel plate contains copper, chromium, nickel alloy elements, which has corrosion resistance feature. The surface of EN S355J2WP steel plate can form a layer of dark brown oxidation, which inhibits deeper penetration since corrosion by atmosphere. So atmospheric corrosion resistant EN S355J2WP steel plate can reduce the cost of need for painting and costly rust-prevention maintenance over the years.
