Websmooth coating, a spangle-free practice is recommended. Galvanneal coatings are produced by using a reheating furnace above the zinc bath to convert the still molten galvanize coating to a zinc-iron alloy. By heating to 590°C for a few seconds, the zinc and iron diffuse into each other, creating a zinc-based coating with a bulk 10% iron content. Production of galvannealed sheet steel begins with hot dip galvanization of sheet steel. After passing through the galvanizing zinc bath the sheet steel passes through air knives to remove excess zinc, and is then heated in an annealing furnace for several seconds causing iron and zinc layers to diffuse into one another causing the formation of zinc-iron alloy layers at the surface. The annealing step is performed with the strip still hot after the galvanizing step, with the zinc sti…
