Factory Pregalvanzied Greenhouse Pipe Square Tubing Round Pipes
Product Description
The hot-dip galvanized steel pipe is made by reacting the molten metal with the iron substrate to produce an alloy layer, thereby combining the substrate and the plating layer. 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 washed in an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride. Hot dip plating bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The complex physical and chemical reaction between the steel tube substrate and the molten plating solution forms a tightly corrosion-resistant zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe base. Therefore, its corrosion resistance is strong.
The pipe can be customized according to the thickness, length, wall thickness and steel grade of the galvanized layer. Qingcheng has many years of production experience, high quality products, exports to more than 50 countries.
