Galvannealed Steel begins with the same process as hot dipped galvanizing process. After coming out of the zinc bath, the material is then heated in an annealing furnace, which causes the iron and zinc layers to diffuse into one another creating a zinc-iron alloy layer. The finished coating will have a matte appearance that is hard and brittle and great for paint adhesion. Galvanneal will also have better spot weldability than galvanized steel. Some common uses of galvannealed steel are automotive components, construction, garbage and linen chutes, signs, guardrails, and bridge components.
