Hot-dip galvanised steel coil (GI) is made by passing a fully hardened steel sheet, which has undergone a pickling and rolling process, through a zinc pot, thereby coating the surface with a zinc film. Due to the properties of zinc, it offers excellent corrosion resistance, paintability and workability. Typically, the process and specifications for hot-dip galvanised steel sheet and galvanised steel coil are essentially the same.
Hardness: soft (normal), hard, full hard
Zinc coating: 30-275 G /M², or on request
Zinc pattern: large zinc pattern, small zinc pattern, no zinc pattern
Surface finish: fingerprint resistant, chromate, oiled, unoiled
Steel Grade:Dx51D,Dx52D,Dx53D,DX54D,S220GD,S250GD,S280GD,S350GD,S350GD,S550GD； SGCC,SGHC,SGCH,SGH340,SGH400,SGH440,SGH490,SGH540,SGCD1,SGCD2,SGCD3,SGC340,SGC340,SGC490,SGC570; SQ CR22(230),SQ CR22(255),SQ CR40(275),SQ CR50(340),SQ CR80(550),CQ,FS,DDS,EDDS,SQ CR33(230),SQ CR37(255), SQCR40(275),SQ CR50(340),SQ CR80(550);
Galvanised steel coils are thin steel sheets that are dipped into molten zinc in order to attach a layer of zinc to the surface. This is an effective method of corrosion protection that extends the life of the metal material.
Classification of galvanised steel substrate
Classification of zinc spangle
| SURFACE TREATMENT | DESCRIPTION OF USE |
| CHROMATE PASSIVATION(C) | Surface treatment for high-strength steel plates after hot-dip plating to reduce white rust during transport and storage |
| Chrome-free passivation(C5) | Surface treatments that require limiting the amount of hexavalent chromium, etc. in passivation solutions that are harmful to the environment and humans |
| Anti-finger print(N) | Surface treatment after the passivation process, which acts as a lubricant during processing, prevents fingerprints from staining during operation, and prevents premature blackening of the surface during use. |
| Chrome-free and fingerprint resistant(N5) | Surface treatment after the passivation process, in the process of lubrication, to prevent the operation of the fingerprint staining, to prevent the use of the surface of the process of premature blackening, and at the same time, the requirement to limit the fingerprint-resistant film harmful to the environment and human body, such as hexavalent chromium content |
| Oiled(O) | Surface treatment added after the passivation process to further reduce rusting during long-distance transport and long-term storage |
