Galvanneal Vs Galvanized Steel

December 14, 2019

Mechanic trucks are continuously exposed to the elements — and that makes rust protection a top priority. Corrosion can spread quickly, eating away at the paint and eventually the body. Steel service bodies typically require galvanization, which is the process of applying a thin coating of zinc to the base metal to prevent rust formation and prolong the lifespan of the product. Another option is to use a variation of galvanized steel known as galvanneal.

Galvanneal vs. Galvanized Steel: What’s the Difference?

Both galvanneal and galvanized steel undergo a hot dip zinc coating process designed to provide enhanced service body rust protection. However, galvannealed steel features an additional step called “annealing,” which is a heat treatment technique that promotes diffusion alloying between the steel surface and the molten zinc coating.

While this procedure improves formability and paint adhesion, it produces a duller matte finish than galvanization. A galvannealed finish is generally recommended for parts that will undergo painting or powder-coating, which often applies to truck service bodies.

A60 vs. A40 Coating

Galvannealed steel is also available in two different coating weights: A40 and A60. The number after the “A” refers to the thickness of the coating. A60 exhibits a thickness of approximately 0.0005 inches, which is far greater than that of A40. Thus, A60 is the better choice for achieving maximum service body rust protection.
