Q235 galvanized pipe is a surface galvanized sheet with yield strength of 235MPa.
Q195 galvanized pipe is a surface galvanized sheet with yield strength of 195MPa. Hot-dip galvanized steel pipes are widely used in the manufacturing industries of construction, machinery, coal mining, chemical industry, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, shed construction, etc.
DC01 Galvanized steel pipe is used for automobiles, sanitary ware, food machinery, pressure vessels, nuclear power, chemical equipment, elevators, rail transit, machinery manufacturing, structural piping, and architectural decoration.
G550 Galvanized pipe belongs to high-strength series galvanized sheet, with high requirements for tensile strength and yield strength. Its minimum yield strength is 560Mpa, minimum tensile strength is 650Mpa, and zinc layer thickness is 275g/m2. It has strong corrosion resistance and is mainly used for building structures with high strength requirements, such as Z-shaped steel, C-shaped steel, floor bearing plate, etc.
