Hot-Dip Galvanizing Line

  
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.Manufacturing capacity: 0.1-0.3 million tons/year
