Hot-dip galvanizing method is the main anti-corrosion process in the steel industry at present, its products have the advantages of long service life, uniform coating, strong adhesion, maintenance free, and its adaptability to the shape and size of products, also has incomparable advantages. In the production of hot-dip galvanizing, the thickness, toughness and surface state of zinc layer can also be well controlled. Therefore, the hot-dip galvanizing process has been continuously developed and is widely used worldwide.

The main steps of the hot-dip galvanizing process are: degreasing → pickling → dipping flux → hot-dip galvanizing → passivation → drying inspection
