S355J2W steel, EN 10025-5 S355J2W steel sheet/Plate, S355J2W improved atmospheric corrosion resistance steel.

S355J2W steel is a kind of improved atmospheric corrosion resistance steel. Improved atmospheric corrosion resistance steel means weathering steel or atmosphere corrosion resistance steel.

Weather resistance corrosion steel coil S355J2W.Unlike unalloyed constructional steel plate,when copper is added as an alloy in weather resistant steel plate S355J2W,there would automatically form a barrier layer which can prevent atmosphere,moisture and other corrosion elements.This layer contains alkaline copper sulphate.

Like all weather resistant steels, S355J2W is self protecting – the material rusts over time due to the reaction with chemical elements in the air. This rust layer acts a protective barrier which prevents further oxidation. The steel is economical to use and is fully recyclable.
