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.

1. Black parts inspection → hanging material → degreasing → rinsing → pickling → cleaning → dipping agent → hot air drying → hot dip galvanizing → inside and outside blowing → cooling → passivation and rinsing → unloading → inspection, dressing → typing labeling → packing into storage and transportation.

Galvanized strip → uncoiling → stretching → rolling → welding → scraping → passivation and rinse → zinc filling → shaping → typing mark → cutting → packing → drying → weighing.

1. Low processing cost: the cost of hot-dip galvanized rust prevention is lower than that of other paint coatings.

4, the toughness of the coating is strong: the galvanized layer forms a special metallurgical structure, which can withstand
mechanical damage during transportation and use.
5, comprehensive protection: every part of the plated parts can be plated with zinc, even in the depression, sharp corners and hidden places can be fully protected.
6, save time and effort: galvanizing process is faster than other coating construction method
