Spangle Classification
1. Coating of normal zinc coating Spagle
During the normal solidification process of zinc layer, zinc grains grow freely to form a coating with obvious zinc flower morphology.
2. Small zinc flowers, minimized spangle coating
During the solidification process of zinc layer, the zinc grains are artificially limited to form as fine zinc flower coating as possible.
3. Zinc free coating spangle-free
By adjusting the chemical composition of the bath, the coating does not have visible zinc flower morphology, uniform surface.
4. Zinc - Iron alloy coating
After heat treatment of the steel strip through the galvanized tank, the entire coating into zinc and iron alloy layer, this coating appearance is dark gray, no metallic luster, easy to powder in the violent forming process, suitable for in addition to general cleaning, without further treatment can be directly painted coating.
5. Differential coating of differential coating
On both sides of galvanized steel plate, different zinc layer weight coating is required.
6. The whole light skin pass
Finishing is a cold rolling of galvanized steel sheet with a small amount of deformation for one or more of the following purposes.
Improve the surface appearance of galvanized steel plate or suitable for decorative coating; The phenomenon of slip line (Lueders line) or fold line is temporarily reduced to the minimum when the finished product is not processed.
