Product Description

Product Description

In order to prevent the surface of the steel plate from being corroded and extend its service life, the surface of the steel plate is coated with a layer of metal zinc, which is called a galvanized plate.

Classification

Hot dip galvanized steel [HDG/HDGI]
The sheet steel is immersed in the melted zinc tank so that the surface is adhered to a layer of zinc sheet steel. At present, it is mainly produced by continuous galvanizing process, that is, the steel plate into a roll is continuously dipped in the melting zinc plating tank to make galvanized steel plate, and the product does not rust in a few years.
 

Electro galvanized steel [EG/EGI]
The process of forming a uniform, dense, well-bonded deposit of metal or alloy on the surface of a part. Compared with hot dip galvanizing, the zinc layer of electric galvanizing is thinner, usually in 10~70g/m2, and the galvanized steel plate manufactured by electroplating has good processability. However, the coating is thin, the corrosion resistance is not as good as the hot-dip galvanized sheet, and the electric galvanizing is generally rusty for half a year.

Surface treatment
 

Surface treatment	Goal
Skin passed	(1) Improve plate shape and flatness; (2) Reduce or eliminate the yield platform of the steel plate, so that the phenomenon of slip line generated when the coated steel plate is used for forming processing is temporarily reduced or eliminated; (3) flatters the crystal flower of the coating to reduce the fluctuation of the coating surface; (4) Given surface roughness.
Chromated/Passivated	Coating surface → Chemical conversion film (passivation film) → Protective coated steel strip does not produce white rust for 3 to 6 months under normal storage and transportation conditions.
Anti fingerprint/AFP	Commonly used in household appliances
Oiled	Reduce white rust during transportation and storage.

Grade



Application



Whether it is the construction industry such as ventilation pipes, floor bearing plates, rolling shutter doors, iron barrels, rain pipes, roof grilles, or home appliance shell, door and window products, kitchen supplies and other home appliance industries, there are aluminized rolls!!!!!!!!!!!!!!
