19*19 38*38 Special Pre Galvanized Steel Tube

Firstly, the steel strip used for pipe making is pickled. In order to remove the iron oxide on the surface of the strip steel, it is cleaned by ammonium chloride or zinc chloride aqueous solution or mixed solution tank of ammonium chloride and zinc chloride, and then sent to the hot dip galvanizing tank. Then air dry and make a pipe. The coating is uniform and bright, and the amount of zinc plating is small, which is lower than the cost of producing hot-dip galvanized pipe.
