Galvanized Steel Coil
Baowu high quality 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. Hot-dip galvanizing is the process of applying a protective zinc coating to a steel sheet or iron sheet, to prevent rusting. * Excellent anti-corrosion, paintability, and processability due to the self-sacrificing characteristic of zinc. * Available to select and produce the desired amount of zinc gilded and in particular enables thick zinc layers(maximum 275g/m2). * Classified as either zero spangle or extra smooth depending on whether the sheet undergoes skin pass treatment.
Surface treatment of galvanized coils
1. Passivation C
2. Oil O
3. Lacquer seal L
4. Phosphating P
5. Do not process U
1 passivation
The galvanized layer is passivated to reduce folding corrosion (white rust) under tidal temperature storage and transportation conditions. However, the anti-corrosion performance of this chemical treatment is limited and, moreover, hinders the adhesion of most paints. This kind of treatment is generally not used in the zinc-iron alloy coating. Except for the smooth surface, as a routine, the manufacturer conducts passivation treatment on other types of zinc coating.
2 oiled
Oiling can reduce steel plate corrosion under wet storage and transportation conditions, and re-oiling steel plates and steel strips after passivation treatment will further reduce corrosion under wet storage conditions. The oil layer should be able to be removed with a degreasing agent that does not damage the zinc layer.
3 paint seal
An additional corrosion protection, especially anti-fingerprint properties, can be provided by applying a very thin film of transparent organic coating. Improves lubricity when forming and acts as an adhesion 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 anti-corrosion performance 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 forming performance.
not deal with
The steel plates and strips supplied according to this standard may not be passivated or oiled or painted or phosphating and other surface treatments are required only if the orderer puts forward a request not to be treated and is responsible for it.
