Technical Processing of galvalume steel in coils:

 

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
