ASTM A653 Zinc Coated Galvanized Steel Coil Z30 - 275 Hot Dipped DX51D
ASTM A653 Z30 - 275 Zinc Coated Galvanized Steel Coil Hot Dipped DX51D
The main production process of galvanized steel coil: on the volume → double open roll → cut head, cut tail → welding → alkaline wash → brushing → → electrolytic cleaning → secondary brushing → hot water rinse → hot air drying → entry loop → continuous annealing → heat Dipping galvanized (ceramic zinc pot) → Air knife purging → → Air cooling after plating → Water quenching → Smoothing machine (reserved) → Tension leveler → Passivation (preservation of fingerprint resistance) → Export looper → Oiled → Sheared → Take-up → Unwinding → Weighing → Packaging.
