- Hot-dip the cleaned steel sheets into the molten zinc for 25-40 minutes to form a protective coating.
- Apply colour coating if required.
- Feed sheets into a corrugated steel sheet machine to press the profile using rolling dies.
- Cut the sheets to desired length, perform quality inspection, pack and dispatch.
