Galvanized Iron Steel:
Galvanized iron coil and sheet refer to steel coils and sheets that have undergone a galvanization process. This process involves coating the steel with a layer of zinc to protect it from corrosion.
Galvanized sheet coils can therefore be divided into hot-rolled galvanized sheet coils and cold-rolled hot-dip galvanized sheets coils, they are mainly used in construction, home appliances, automobiles, containers,Transportation and household business and other fields. Especially steel structure buildings, automobiles Manufacturing, steel silo manufacturing and other industries. They are mainly characterized by:Strong corrosion, good surface quality, benefit from deep processing, economical and practical
The advantages of galvanized steel：
The main advantage of galvanized steel is its corrosion resistance. The zinc coating serves as a barrier between the steel and the environment and will sacrifice itself in order to protect the underlying steel; Meaning the zinc will degrade much sooner than the steel itself. Additionally, it offers good processability and formability.

Why use Zinc to produce galvanized steel coil?
Zinc is a blue-white metal having a melting point of 419.4 ° C and a density of 7.14 g/cm 3 . Zinc has moderate ductility. Zinc does not change in dry air at room temperature. In the moist air, the zinc surface forms a dense film of zinc carbonate, which protects the interior of the zinc from corrosion. Since zinc has such an excellent property, zinc is plated on the surface of the steel sheet to prevent corrosion, and this steel sheet is called a galvanized sheet.
Advantages of Galvanized Steel Coil:
After the steel coil or plate is galvanized, the service life can be greatly extended. If the zinc layer on the steel sheet is not destroyed, the zinc can prevent the corrosive medium (water, oxygen, carbon dioxide, etc.) from contacting the surface of the steel sheet, which is exactly the same as the anti-corrosion effect of the tin plating layer. However, if the galvanized layer is destroyed and the iron of the individual parts is exposed to the surface, since the chemical properties of zinc are more active than iron, zinc and iron form micro-batteries during the etching process, and zinc is the anode of the micro-battery. It is dissolved, and iron is protected by the cathode.
Galvanized coil show:
For galvanized coils, the sheet steel is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also manufactured by hot dip method, but immediately after being out of the tank, it is heated to about 500 ℃ to form an alloy coating of zinc and iron. This galvanized coil has good paint adhesion and weldability.
