Hot Dip Galvanized Pipes are made by reacting the molten metal 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 hot dip bath.

Product Features
1. The surface of the steel pipe is treated with anti-embroidery, which is more durable, not more than too fast oxidation, and will not form white rust on the steel pipe;
2. Fully protect the steel pipe. After heating, every part of the steel pipe is plated with zinc, and the concave and convex parts are protected;
3. It has the characteristics of anti-corrosion and wear resistance, which makes the steel pipe last longer;
4. save the time of oiling or painting, and the construction is more convenient
