Plus the corrosion protection of zinc.
Hot dip galvanizing is the molten matrix of the base metal and the reaction of the iron alloy layer, making the combination of both the substrate and coating.
First pickle steel articles, remove the iron oxide of the surface of the steel parts, after pickling, go through an aqueous solution of 
zinc chloride and ammonium chloride or a mixed aqueous solution of tank cleaning, and then sent to a thermal dip tank to achieve galvanizing steel.
Hot-dip galvanized has advantages like even coating, strong adhesion, and long service life.
