Cold-rolled galvanized steel coil

Cold-Rolled Galvanized Steel Coil

Product Description

This product is a cold-rolled steel coil coated with a zinc layer through hot-dip galvanizing. The process involves passing the cold-rolled steel through a bath of molten zinc, providing corrosion resistance. It belongs to the galvanized coil category in our product line.

Key Specifications
