[0002] Hot-dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to first pickle the steel parts to remove the iron oxide on the surface of the steel parts. After pickling, they are cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to a hot dip tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life.
