Hot Dipped Galvanized DX51D GI Steel Coil With Small Spangle

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. The process involves pickling iron and steel parts to remove surface oxides, followed by cleaning in ammonium chloride or zinc chloride solutions before immersion in the hot-dip plating bath. This method provides uniform coating, strong adhesion, and long service life.
