What is the purpose of the galvanized coils

Galvanized coils is the thin steel plate into melting zinc trough, the sticking of a layer of zinc sheet. Hot galvanized coils can be divided into cold rolled and hot rolled galvanized coil, galvanized coil, at present mainly adopts continuous galvanizing process, namely the continuous roll of steel plate in the melting made of galvanized steel with zinc plating bath.Because the galvanized coils have strong corrosion resistance, good surface quality, beneficial to deep processing, economical and practical characteristics, so is widely used in construction, household appliances, automobiles, containers, transportation and possessions, and other fields. Especially in steel structure building, automobile manufacturing, steel silo manufacturing and other industries.

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, it is required to have different layers of coating weight.

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.
