What are the classifications of galvanized coil coatings?

1. Normal spangle coating

During the normal solidification process of the galvanized coil zinc layer, the zinc grains grow freely and form a coating with obvious spangle morphology.

2. Small spangle coating

During the solidification process of the zinc layer, the zinc grains are artificially restricted to form a spangle coating as small as possible.

3. No spangle coating

The coating obtained by adjusting the chemical composition of the plating solution has no visible spangle appearance and a uniform coating on the surface.

4. Zinc-iron alloy coating

Heat treatment is carried out on the steel strip after passing through the galvanizing bath so that the entire coating forms an alloy layer of zinc and iron. The appearance of this coating is dark gray, without metallic luster, and it is easy to pulverize during the violent forming process. Except for cleaning, coatings can be painted directly without further treatment.

5. Different thickness plating

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

6. Finishing

Skin pass is a small deformation cold rolling process on galvanized steel sheet for one or more of the following purposes. Improve the surface appearance of galvanized steel sheets or be suitable for decorative coating, so that the phenomenon of slip lines or creases produced during the processing of finished products can be temporarily minimized.
