Galvanized steel is standard steel that is coated in zinc to provide enhanced corrosion resistance. The galvanized protective coating protects the iron steel substrate from corrosion due to moisture, saturated environmental conditions, or ambient humidity. The galvanization process produces a sacrificial layer between the zinc protective layer and the steel, allowing maximum protection from rust inducing elements Size:customizable Type: GI&GL Plate/CoilGI&GL Pipe\PPGI&PPGL Coil\Corrugated Steel Sheet Material:DX51D+Z/DX52D+Z/DX53D+Z/DX54D+Z/DX56D+Z/SGCC/SGCD1/SGCD2/SGCD3/SGCD4/SGC340/S220GD+Z/S250GD+Z/S280GD+Z/S320GD+Z, etc.
