Audited Supplier ASTM A653/A653M CS Type A Galvanized Steel Tube Cold Rolled Pickled Sheet Automotive Round Steel Tube
Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The hot-dip galvanized steel pipe base and hot-dip galvanized steel pipe undergo complex physical and chemical anti-galvanizing to form a zinc-iron alloy layer with a tight corrosion-resistant structure.
The hot-dip galvanized pipe is to make the molten metal and the iron matrix react to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after the pickling, it is cleaned in a tank of ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to In the hot dip plating tank.
