Galvannealing

Galvannealing is the outcome of combining the annealing and galvanizing processes in order to produce a specialized coating on steel. The process of galvanization is performed via hot-dipping and instantaneous annealing, which produces a matte gray finish.

Galvannealed steel is a steel that is coated in a combination of zinc and iron. This steel is most popular in car manufacturing, although it can be applied in various industries, such as ships and structure construction.

The Process

Galvannealed is a zinc-iron alloy product, where the base metal is coated by the hot-dip process, then heated to induce alloying between the molten zinc coating and the steel. The resulting finish is a dull matte surface. Galvannealed steel is conducive to welding and the surface is excellent for paint adhesion.
