Hot Dipped Zinc Coating GI Steel Coil 22 Gauge Z220 Regular Spangle
22 Gauge Z220 Regular Spangle Hot Dipped Zinc Coating GI Galvanized Steel Coil
Electrogalvanizing, commonly known as cold galvanizing, is an electrochemical method.
The zinc ingot is used as the anode. After the zinc atom loses electrons,
it becomes an ionic state and dissolves into the electrolyte.
The steel strip is used as the cathode.
Zinc atoms are deposited on the surface of the steel strip, forming a coating.
There is a big difference in the amount of galvanizing between hot-dip galvanized sheet and electro-galvanized sheet.
The galvanizing amount of hot-dip galvanizing cannot be too small, generally the minimum is 50-60g/m2 on both sides,
and the maximum can reach 600g/m2. The galvanized layer of the electro-galvanized sheet can be very thin,
the minimum is 15g/m2, but if the coating is thicker, the production line speed is very slow,
which is not suitable for the technological characteristics of modern units, generally the maximum is about 100g/m2.
Because of this, the production of electro-galvanized sheet is greatly restricted.
