Hot-dip galvanized pipe 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 pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the in the hot dip bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The hot-dip galvanized steel pipe substrate undergoes complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant zinc-iron alloy layer with a compact structure. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate, so it has strong corrosion resistance.
Construction Use: Hall Structure, Sea Trestle, Airport Structure, Shipbuilding, Security Door Frames, Garage Doors,
Strengthening Liners of Steel Doors and Windows, Indoor Partition Walls, Cable Bridge Structures and Expressway
Safety Guards, Balustrade, Decorating, Residential, Ornamental Pipes.
