Our Hot Dip Galvannealed Steel, is continuously coated on both sides with a zinc-iron alloy. Galvannealed steel is a specialized variation of galvanized steels where induction heating is used to alloy the zinc coating with the steel to create a zinc-iron coating. The hot dip process, pioneered by our mills, provides a tight metallurgical bond between the steel and coating. This process results in a material with the strength and formability of steel plus the corrosion protection of the zinc-iron coating. Zinc protects the base metal by providing a barrier to corrosive elements and also by the sacrificial nature of the coating. Hot Dip Galvannealed Steel is available with special surface finishes, tailored for specific applications, and in a variety of base metal grades and coating weights.
