Electro galvanized
steel sheet (SECC):
Fingerprint resistant, with excellent corrosion resistance, and
maintains the processability of cold rolled sheet.
Differences between electrogalvanized sheet and hot-dip galvanized
sheet1. Galvanizing, as a metal anti-corrosion method, usually
involves placing the steel structure to be derusted into a zinc
solution at around 500 ºC, allowing the zinc layer to adhere to the
surface of the steel structure. Electroplating uses electrolysis to
attach a metal film to the surface of materials such as metals,
resulting in a uniform surface texture, corrosion resistance, wear
resistance, and a more aesthetically pleasing appearance.2. The
galvanized coating is relatively thick, generally ranging from 30
to 60 microns, and has a high anti-corrosion ability. Steel parts
suitable for outdoor work. The surface of the electroplated
workpiece is smooth and flat, but due to the relatively thin
coating, which is generally within 5-30 microns, the anti-corrosion
time will be relatively short. They are all used for rust
prevention of indoor components.3. Galvanizing uses the principle
of zinc resistance to atmospheric corrosion to conduct
electrochemical protection for steel and other materials. The Zinc
carbonate protective film on the surface can slow down the speed of
zinc corrosion. Even if it is damaged, it will form a zinc film
again. Electroplating is the use of chemical methods to separate
zinc alloys into zinc ions, which have attached to the surface of
steel. The zinc layer formed by this method is generally thin, and
steel is prone to corrosion under normal circumstances.4. The outer
surface of the electroplating is relatively smooth and bright. The
electroplating layer processed with color passivation will appear
yellow green, while the electroplating layer processed with white
passivation will appear cyan white. Generally, there is only a
small amount of zinc layer on both ends of the galvanized steel
pipe, and there is no zinc coating further inside. The galvanized
outer surface is relatively rough, dark in color, and generally
presents a silver white color. Due to the production process, some
water marks and nodules are generated on the surface, which does
not emit light or reflect light. The galvanized steel pipe has a
complete galvanized coating on both the inside and outside.Photo
