A. Specification:
Galvanized sheet or coil is defined as a carbon steel sheet coated with zinc on both sides.
Continuous hot dipping is the main process used to produce galvanized sheet and coil. Generally speaking, the hot dip process consists of passing the steel through a bath of molten zinc. The result is a layer of zinc tightly adhering to the base metal through an iron-zinc bonding layer. Our hot-dipped galvanized products are manufactured to ASTM A653 specifications.
