Hot dipped galvanized steel coil, the thin steel plate is immersed in the molten zinc tank, so that a thin steel plate with a
layer of zinc is adhered to the surface. At present, the continuous galvanizing process is mainly used for production, that is,
the rolled steel sheet is continuously immersed in a galvanized bath with molten zinc to make a galvanized steel sheet;
alloyed galvanized steel sheet. This kind of steel plate is also manufactured by hot dipping method, but immediately after
leaving the tank, it is heated to about 500°C to form an alloy film of zinc and iron. This galvanized coil has good paint
adhesion and weldability.
Galvanized steel coils are widely used in construction, communications, electricity, transportation, energy, automobiles,
light industry (household appliances), agriculture, animal husbandry and fishery, petrochemical and other industries.

(1) Normal spangle coating
In the normal solidification process of the zinc layer, zinc grains grow freely to form a coating with obvious spangle morphology.
(2) Minimized spangle coating
During the solidification of the zinc layer, the zinc crystal grains are artificially restricted to form the smallest possible spangle coating.
(3) Spangle-free coating spangle-free
It is obtained by adjusting the chemical composition of the plating solution, does not have a visible spangle morphology, and has a uniform surface coating.
