• We shipped to a 40 ft high cabinet in Littleton in August.Let us introduce the definition and  application of galvanized coil coating

Definition of galvanized coil coating

1. normal zinc flower coating

During the normal solidification process, the zinc grains grow freely and the coating with obvious zinc flower morphology is formed.

2. small zinc flower coating

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

3.no zinc flower coating

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. the thickness of the coating

On both sides of galvanized steel plate, different zinc layer weight coating is required.

6. finishing

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; So that the finished product is not processed when the phenomenon of slip line or fold grain temporarily reduced to the minimum.

What is the application of galvanized coil?

Galvanized coil is a thin sheet of steel immersed in a melting zinc tank, so that the surface of a layer of zinc thin sheet. Galvanizing rolls can be divided into hot rolled galvanized sheet rolls and cold rolled hot galvanized sheet rolls. At present, continuous galvanizing process is mainly used to produce, that is, the rolling steel plate is continuously immersed in the melting zinc plating tank to make galvanized steel plate. Because galvanized coil has strong corrosion resistance, good surface quality, conducive to deep processing, economic and practical characteristics, so it is widely used in construction, household appliances, automobiles, containers, transportation and home industry and other fields. Especially steel structure construction, automobile manufacturing, steel plate warehouse manufacturing and other industries.
