(1) Normal zinc flower coating

During the normal solidification process, the zinc coating is formed by the free growth of zinc grains and has a distinct zinc flower morphology.

(2) Small zinc flower coating

During the solidification process of the zinc coating, zinc grains are artificially restricted to form a zinc flower coating as fine as possible.

(3) Zinc-free flower coating

The coating obtained by adjusting the chemical composition of the plating solution, which does not have the visible zinc flower morphology and has a uniform surface.

(4) Zinc-iron alloy coating

Heat treatment is carried out on the steel strip after passing through the galvanizing bath solution to form an alloy layer of zinc and iron on the entire coating. This coating appears dark gray and lacks metallic luster. It is prone to powdering during the vigorous forming process and is suitable for coatings that can be directly painted without further treatment except for general cleaning.

(5) Differential thickness coating

For both sides of galvanized steel plates, coatings with different zinc layer weights are required.

(6) Smooth and tidy

Finishing is a cold rolling process with a small amount of deformation carried out on galvanized steel sheets for one or more of the following purposes.

Improve the surface appearance of galvanized steel plates or be suitable for decorative coatings; To temporarily minimize the phenomenon of no sliding lines (Ludes lines) or wrinkles produced during processing on the finished product, etc.
