The biggest advantage of galvanized steel plate is excellent corrosion resistance, painting, decoration and good formability. With the development of industry, hot dip galvanizing products have been used in many fields. The advantage of hot dip galvanizing is that the anti-corrosion life is long and it has been a popular anti-corrosion treatment method to adapt to the environment widely. It is widely used in power tower, communication tower, railway, highway protection, road light pole, Marine component, building steel structure component, auxiliary facilities of substation, light industry and so on.

Galvanized steel plate is coated with a layer of metal zinc on the surface of the steel plate to prevent corrosion on the surface of the steel plate and prolong its service life. This kind of galvanized steel plate is called galvanized steel plate.
Surface condition: Due to the different treatment methods in the coating process, the surface condition of the galvanized sheet is also different, such as ordinary spangle, fine spangle, flat spangle, no spangle and phosphating surface. German standards also specify surface grades.
The galvanized sheet should have a good appearance and should not have defects that are harmful to the use of the product, such as no plating, holes, cracks and scum, over-plating thickness, scratches, chromic acid dirt, white rust, etc. Foreign standards are not very clear about specific appearance defects. Some specific defects should be listed in the contract when ordering.

Hot Dipped Galvanized Steel Sheet in Coil (GI) is produced by passing the Full Hard sheet which has undergone
the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has
excellent corrosion resistance,paintability, and workability due to Zinc's characteristics. Usually, hot-dipped
galvanized steel sheet and galvanized steel coil process and specifications are basically the same.
