A500 4 x 4 inch galvanized square steel pipe

Hot-dip galvanized pipe is formed by the reaction of molten metal and iron matrix to form an alloy layer, so that the matrix and the coating are combined. The hot-dip galvanized pipe will first pickle the steel pipe to remove the iron oxide on the surface of the steel pipe. After pickling, use ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride to wash it for the second time, and then send it to hot dipping. in the plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. The hot-dip galvanized steel pipe substrate and the molten plating solution produce complex physical and chemical reactions to produce a corrosion-resistant zinc-iron alloy layer with a dense structure. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate, and has strong corrosion resistance.
