The pre-galvanized steel tube refers to welded tube which undergo degreasing, rust removal, phosphorization, and drying processes before galvanization. The treatments before galvanization allow the product to be conveniently plated with a zinc coating, and also ensure uniform coating thickness, strong coating adhesion, and improved corrosion resistance. The per-galvanized steel tubes are widely used in heat, water, and natural gas supply systems, agricultural greenhouse construction, steel structure construction, as well as low and medium pressure piping system.
