1. Galvanized Steel Coil simple introduction
Galvanized 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, and home appliances
2. Galvanized 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. Galvanized 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. Galvanized 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
