China Aluzinc Galvanized Steel Galvanised Metal Plate Galvanized Iron Steel

1. Hot Dipped GI Steel Coil simple introduction
Hot Dipped GI Steel Coil,sometimes also called full hard galvanized steel coil,is typically utilized to
make corrugated plate of roofs.Besides, it can also used in many other fields,such as machinery
fields, light industry, construction sector, transportation field, chemical industry,home appliances
2. Hot Dipped GI Steel Coil technical processing
1) Uncoiled and sheared
2) Cleaned using a caustic solution, which can remove oil/grease, dirt, and paint
3) Entry looper to revised and then annealing furnace
4) Steel is dipped into the molten zinc bath
5) Cooled in a quench tank to reduce its temperature
6) Post treatment and crimper
3. Hot Dipped GI Steel Coil quality control
Strict procurement process---skillful technical workers---final products inspection(resistance to
corrosion,salt spray test, exposure test, machinability, thermal resistance)---standard packing
4. Hot Dipped GI Steel Coil advantages
1) Zinc coating has good adhesion
2) Resistant to corrosive factors
3) High strength&quality
4) Strict quality control system
5) Standard export sea-worthy packing
