Sch40 Sch80 Hot Dip Galvanized Steel Pipe 10.2-165mm OD with 2.0-5.5mm Wall Thickness for Construction and Industrial Applications
Zhengde galvanized steel pipes are available in both cold-galvanized and hot-dip galvanized variants, manufactured as round pipes and 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 before immersion in the hot-dip coating tank. This method ensures uniform coating distribution, strong adhesion, and extended service life.
