The main technology of Galvanized steel sheet is proceeding by the chemistry degrease and electro
analysis with the cold rolled steel coil and sheet, clean the oils on the surface of steel, sufficiently heated
to the proper temeperature for zinc coating, pass by level up, strain rectify, and then passivation or annoit etc.
Hot dip zinc is in order to improve anti-erode and prolong the usage period of material, at the same time it can
beautify the surface and add arty.
The hot dip galvanized steel sheet is widely used in such field as light industry, electrical home applicances,
motorcar and construction. In the field of construction, it used un all kinds if industrial and civilian construction
as light steel keel, air conditioner system, construction panel, etc. The hot dip galvanzied steel coil is also the
main material of PPGI.Specifications
