Zinc Coating

(1) Spangle coating:

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

(2) Minimized 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) spangle-free:

By adjusting the chemical composition of the plating solution, there is no visible spangle morphology 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 that can be painted directly without further treatment.

(5) differential coating:

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

(6) skin pass:

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

Advantages

The main advantage of galvanized coil is that the surface oxidation resistance is strong, which can strengthen the corrosion resistance of parts. In addition, the surface of galvanized roll is clean and beautiful, which enhances the decorative material. Therefore, galvanized products are becoming more and more indispensable materials in manufacturing industry.

How to choose galvanized coilshoos

1. Cost-effective solution

Compared to GL or color coated steel coils, galvanized steel coils are the most cost-effective solution, but with similar features such as great corrosion resistance, good appearance, etc.

2. Wide range of applications

Galvanized steel coil can be easily processed into different applications. It is widely used in construction, home appliances, automotive containers, transportation, and other fields.

3. Easy to transport

Compared with GI steel sheets, the coil is easier to transport. In this way, it will save your transportation cost.

Application

Because galvanized coil has the characteristics of strong corrosion resistance, good surface quality, good for deep processing, economical and practical, it is widely used in construction, home appliances, automobiles, containers, transportation and household business. Especially steel structure construction, automobile manufacturing, steel silo manufacturing and other industries.
