S235J2W steel plate and coil is a kind of resistance to atmospheric corrosion steel under the standard of ASTM A588,S mean S235J2W grade could be used in structural steel projects, 235 is the min yield strength. J0 ,J2 and K2 standard for the impact degree and energy in 0 temperature. W means that the mainly different in their carbon and phosphorus contents and availability.

S235J2W Stop Rusting reason:
Since the S235J2W steel suffers the corrosion by rain, snow, ice, fog and other meteorological conditions, the surface of the metal S235J2W can form a coating of dark brown oxidation, which inhibits deeper penetration because of containing high Chromium, Copper ect. Alloy composition. So S235J2W steel saves the cost of need for painting and costly rust-prevention maintenance over the years.
