7. Galvannealed - Wikipedia

   en.wikipedia.org/wiki/Galvannealed

   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.

9. Sheet metal - Wikipedia

   en.wikipedia.org/wiki/Sheet_metal

   The process of flattening metal sheets required large rotating iron cylinders which pressed metal pieces into sheets. The metals suited for this were lead, copper, zinc, iron and later steel. Tin was often used to coat iron and steel sheets to prevent it from rusting. [3] This tin-coated sheet metal was called "tinplate." Sheet metals appeared ...
