Hot-dip galvanizing is the reaction of molten metal and iron matrix to form an alloy layer.
So that the base material and the coating are combined. Hot-dip galvanizing is to pickle the steel parts first. In order to remove iron oxide on the surface of steel parts, after pickling, wash in ammonium chloride or zinc chloride aqueous solution or a mixed solution of ammonium chloride and zinc chloride. Then into the hot-dip coating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life.
