S355J2G3  

S355J2G3 steel, under EN 10155 standard, we can regard S355J2G3 steel as Steel Resistant to Atmospherical Corrosion.

S355J2G3 steel is one mainly of Steel Resistant to Atmospherical Corrosion. S355J2G3 steel is a weather-resistant structural steel with mechanical properties similar to S355J2G2. By adding Cr, Cu and Ni, it formed oxide layers stick firmly to the workpiece surface. This oxide layer prevents further corrosion of S355J2G3 steel.
