1.Galvanized Zinc Coil simple introduction
It 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 more
durable, hard to scratch finish.



2.Galvanized Zinc 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 Zinc 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 Zinc 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
