galvannealed steel
Galvannealed, as the name suggests, undergoes galvanization and annealing. It is essentially a matte zinc-iron alloy coating used to improve paint adhesion and corrosion and surface durability.

Key Features:

  • Manufacturing Process: The hot-dip galvanization of steel creates a zinc layer. An annealing process followed by this causes an interdiffusion of the zinc with the steels surface, giving rise to a zinc-iron alloy coating.
  • Enhanced Properties: It has superior paint adhesion compared with ordinary galvanized steel. Greater corrosion resistance makes it suitable for very harsh environments. A sturdier, more uniform surface reduces flaking or peeling.
  • Common Uses: In the automotive sector (body panels and frames) to make them even more durable. Construction materials, roofing, and siding in relation to the weather. Appliances and electrical enclosures where a durable, paintable surface is needed.

Galvannealed steel is generally found in industries that require a robust, corrosion-resistant metal that can readily be painted, with durability and structural integrity lasting for years into the future.
