Galvanized Steel Coil Advantages, Suppliers


In order to prevent corrosion on the surface of the steel plate to extend its service life, we can coat it with a layer of zinc, thus creating our product alvanized Steel Sheet in Coil.

The galvanized coil is immersed in a molten zinc bath to adhere a zinc-plated steel sheet to the surface. At present, it is mainly produced by a continuous galvanizing process, that is, a coiled steel plate is continuously immersed in a zinc-plated plating tank to form a galvanized steel sheet. It is also produced by hot dip, but immediately after it is taken out, it is heated to about 500 ° C to form an alloy coating of zinc and iron. This galvanized roll has good adhesion and weldability of the coating.

1 Passivation

The galvanized layer is passivated to reduce the occurrence of rust (white rust) under humid and warm storage and transportation conditions. However, the corrosion resistance of this chemical treatment is limited and, moreover, hinders the adhesion of most coatings. This treatment is generally not used in zinc-iron alloy coatings. Except for the smooth surface, as a routine, other types of galvanized coatings are passivated by the manufacturer.

2 Oiled
Oiling can reduce the corrosion of steel plates under wet storage and transportation conditions, and re-coating the steel plates and steel strips after passivation treatment with oil will further reduce the corrosion under wet storage conditions. The oil layer should be able to be removed with a degreaser that does not damage the zinc layer.

3 paint seal
An additional anti-corrosion effect, especially fingerprint resistance, can be provided by applying a very thin transparent organic coating film. Improves lubricity during molding and acts as an adherent primer for subsequent coats.

4 Phosphating
Through phosphating treatment, galvanized steel sheets of various coating types can be coated without further treatment except for normal cleaning. This treatment can improve the adhesion and corrosion resistance of the coating and reduce the risk of corrosion during storage and transportation. After phosphating, it can be used with a suitable lubricant to improve the molding properties.

5 not processed
The steel sheet and steel strip supplied according to this standard may not be passivated, oiled, painted or phosphated and other surface treatments only if the orderer requests non-treatment and is responsible for it.
