Production line of galvanizing plate

The technology is that the cold rolled steel strip runs into zinc pot after annealing and rinse. It is equipped with skin rolling, chromate coating and oiling according to different utility. There are two kinds of products based on the base plate, common galvanized sheet and hot-rolled galvanized sheet. Used widely for manufacture of automobile, household electric appliance, building construction and base plate for color coating etc.
