Hot-dip galvanizing production line

< >

Hot dip (or hot) galvanizing is the processing technique to dip the pretreated base substance of carbon steel into melted liquefied zinc to obtain a protective zinc coat. Due to its good anti-corrosion performance, galvanized plate is vastly applied into the industries of home appliance, decoration, advertisement, and civil construction, etc. Particularly, the home appliance industry (outer shell of air conditioner,  outer shells of washing machine, computer, and microwave oven, etc) has large demands on galvanized and color coated plates. According to the traditional methodology, galvanization can be sorted into United States Steel Corp and Sendzimir 2 methods.
