Product Description

galvanized steel coil brief introduction 
Galvanized steel coil is proceeded by the chemistry degrease and electric analysis with the cold rolled steel coil and sheet, clean the oils on the surface of steel, sufficiently heated to the proper temperature for zinc coating, pass by level up, strain rectify, and then passivation or annoit etc. Hot-dip galvanizing is the process of applying a protective zinc coating to steel sheet or iron sheet, to prevent rusting.

galvanized steel coil advantages
excellent durability
corrosion resistant
high tolerance against extreme weather
excellent heat reflectivity
excellent formability
resistant to wide range of temperatures
excellent tensile strength
fire resistance
recyclable, environment friendly

galvanized steel coil applications
Galvanized steel sheet is widely used in light industry, home appliances,automobile and architecture (as light steel keel, air conditioner system, panel,roof sheet, rolling door ). It is also the base materials for color coated steel sheet.
