Product Description
Hot rolled galvanized steel pipe is to make molten metal react with iron matrix to produce alloy layer, so as to combine the matrix and coating.Hot rolled galvanized steel pipe has the advantages of uniform coating, strong adhesion and long service life.Complex physical and chemical reactions occur between hot dip galvanized steel tube and molten plating solution to form a tightly structured zinc-ferroalloy layer with corrosion resistance. Hot rolled galvanizing can increase the corrosion resistance of steel pipe and prolong its service life. Galvanized pipe has many uses .
Hot dipped round galvanized steel pipe is widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, greenhouse construction and other manufacturing industries.
