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.
