Product Description
NAME: Steel Coil Hot Dip Galvanized Steel
1, Description of Galvanized Steel Coil
Galvanized steel coil is immersed in the melting groove of thin steel plate,adhered to the surface of thin steel plate a layer of zinc. At present, we mainly use the hot-dip continuous galvanizing process. It has characteristics of high corrosion resistance, good quality surface, long service life and deep processing and etc. It mainly used in construction, light industry, automobile, farming and commercial fishing industries.

2, Classification and Code
2,1 Surface Structure and Surface Finishing
Surface | Finishing | Definition |
Regular Spangle | NS | Zinc layer in normal solidification process, zinc grains free growth forming with obvious zinc flower morphology of the coating. |
Minimized Spangle | MS | In the course of solidification, zinc grains are artificially restricted to form as little as possible. |
Zero Spangle | FS | By adjusting the chemical composition of the plating solution, the morphology of the zinc flower is not visible, and the surface of the coating is uniform . |
Zinc and Alloy | ZFS | Through the liquid of zinc plating steel strip for heat treatment, the coating to form zinc and iron alloy layer. The coating appearance is dark gray, without metallic luster.It is easy to powder in the process of severe forming.It is suitable for cleaning in addition to general, without further processing can be directly painted coating |
2,2 Surface Quality Classification and Code
Surface Quality | Normal surface | Higher surface | Advanced surface |
Code | FA | FB | FC |
2,3 Surface Treatament Classification, code and interpretation
Surface treatment | Code | Explanation |
Chromated | C | Through the chromated treatment on the galvanized layer , it can reduce the moist storage conditions produced under fold corrosion.However,the corrosion resistance of this chemical treatment is limited, and the adhesion of most coatings. This treatment in general do not have coating on Zn Fe alloy, except for the entire surface of the light, as a conventional, the factory will do chromated treatment for other types of galvanized coating. |
Oiled | O | Oiling can reduce the corrosion of steel plate under the condition of wet storage, With the treatment of passivation and oiling on the steel sheet and strip, it will reduce the wet storage under the condition of corrosion.The oil layer should be able to remove the absorbent with no damage to the zinc layer. |
Lacquering | L | By coating a layer of thin transparent organic coating film, it could provide an additional protection against corrosion,Especially fingerprint resistant characteristics. In molding, it can improve the lubrication performance, and as a subsequent coating adhesion layer. |
Phosphating | P | Through phosphating treatment, make all kinds of coating types of galvanized steel sheet, in addition to the normal cleaning, no further processing can be coated. This treatment can improve the adhesion and corrosion resistance of the coating, reducing the risk of corrosion during storage and transportation. After phosphating ,it matched with suitable lubricant and improve the forming performance. |
Non treatment | U | Only under the condition that the buyer ask and responsible for the non-treatment.According to the standard,the steel sheet and strip can without Chromated, oiled and phosphating surface treatment. |
