Hot Dipped Galvanized Steel Pipe 12-16 Gauge Sch80 Ss400 S235jr Seamless Construction 10-165mm Diameter
Zhengde galvanized steel pipes are available in both cold-galvanized and hot-dip galvanized variants, manufactured as round pipes or square/rectangular tubes. The hot-dip galvanizing process involves pickling to remove surface iron oxide, followed by cleaning with ammonium chloride or zinc chloride solutions, then immersion in the hot-dip coating tank. This method ensures uniform coating, strong adhesion, and extended service life.
