Product Description

Galvanized steel coil, the thin steel plate is immersed in the melting zinc tank, so that the surface of the thin steel plate with a layer of zinc. The main use of continuous galvanizing process production, that is, the rolling steel plate is continuously immersed in the melting zinc plating tank made of galvanized steel plate; Alloyed galvanized steel sheet. This steel plate is also made by hot dipping, but immediately after being taken out of the tank, it is heated to about 500 ° C to form an alloy film of zinc and iron. Hot dipped galvanized steel coil has good coating tightness and weldability.

Galvanized Steel Sheet Metal Coils Spangle Z275 2.3mm Galvanized Steel Coil
Galvanized Steel Sheet Metal Coils Spangle Z275 2.3mm Galvanized Steel CoilThere are many factors affecting the size of spangle of galvanized steel. When the zinc liquid composition has the conditions for the formation of zinc flowers, the following factors will affect the size of spangle:

(1) Raw material: the thicker the raw material steel plate, the smaller the surface roughness, the larger the steel spangle.
(2) Cooling rate: the faster the cooling rate, the shorter the crystal growth time, the smaller the spangle.
(3) Number of crystal nuclei: The size of spangle is closely related to the number of crystal nuclei of spangle. When the surface of steel base is rough or the surface cleanliness is poor, the spangle is relatively small. Zinc grains are formed on steel base, and the more nuclei there are, the smaller the spangle will be. This principle is used in the production process of small spangles.
(4) Other factors (production environment, etc.).

Surface treatment of galvanized steel coils:
Passivation C/ Oil O/Lacquer seal L/Phosphating P/Do not process D
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.
5.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.
