Hot-dip galvanized steel sheet. The thin steel sheet is immersed in a molten zinc tank to make a layer of zinc thin steel sheet adhere to its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel sheet is continuously immersed in a molten zinc plating tank to make a galvanized steel sheet;
Electrogalvanized steel sheet. This galvanized steel sheet made by electroplating has good processability. However, the coating is thinner and the corrosion resistance is not as good as that of hot-dip galvanized steel sheet;

Galvanized coil, the thin steel sheet is immersed in a molten zinc tank to make a layer of zinc thin steel sheet adhered to its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel sheet is continuously immersed in a plating tank with molten zinc to make a galvanized steel sheet; Alloy galvanized steel sheet. This steel sheet is also made by hot dip method, but after leaving the tank, it is immediately heated to about 500℃ to form an alloy film of zinc and iron. This galvanized coil has good coating adhesion and weldability.

Color coated is in the continuous unit to cold rolled strip steel, galvanized strip steel (electric galvanized and hot galvanized) as the base plate, after surface pretreatment (degreasing and chemical treatment), with the method of roller coating, coated with a layer or multiple layers of liquid coating, after baking and cooling plate. The coated steel plate has light weight, beautiful appearance and good anti-corrosion performance, and can be directly processed, it provides a new raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, furniture industry, electrical industry and so on. It has played a good effect of replacing wood with steel, efficient construction, energy saving and pollution prevention.

Characteristics：Weather proof; heating insulation; fireproof; anti-rust; sound insulation; long life span: more than 20 years. Corrosion Resistance: the aluzinc coating surface protects the base steel not only by providing barrier to corrosion elements, but also by the sacrificial nature of the coating.

Section steel is a strip of steel with a certain cross-sectional shape and size. It is one of the four major varieties of steel (plate, tube, profile, and wire). According to the cross-section shape, section steel is divided into simple section section steel and complex section section steel (special-shaped steel). The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc.; the latter refers to I-beam, channel steel, rail, window frame steel, curved steel, etc.
