Zinc coated steel coil
GB/T-2518 JIS G 3302 EN 10142/10427 ASTM A653.Hot dipped galvanized steel sheet have excellent performance, zinc spangle and coating can be controlled strictly. They are mainly used for building root door; window^ roller shutter door and lightgage steel joist For automobile industry vehicle shell, chassis, trunk lid, oil tank, and fender; metallurgy steel sash back, and electric equipments, such as refrigerator base and shell, and kitchen equipments, color coated steel baseplate etc.
Galvanized Steel Coil
Hot-dip galvanizing is the reaction of molten metal with an iron substrate to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle iron and steel parts first. In order to remove iron oxide on the surface of iron and steel parts, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed solution of ammonium chloride and zinc chloride.And then sent to the hot-dip plating bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
