1. Galvanized steel coil simple introduction:
Galvanized steel coil means that hot roll steel coils has gone through a chemical process. To keep it from corroding, so this protective metal, zinc layers, does not get rusty as easily. The coating also gives the steel a more durable, hard to scratch finish.
2. Galvanized steel coil technical processing:
1)Uncoiled and sheared
2)Cleaned using a caustic aolution, 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 quanlity 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 corrosive4 factors
3)High strength&quality
4)Strict quality control system
5)Standard export sea-worthy packing
