Galvannealed

This sheet steel is heat treated after coating to produce a zinc-iron alloy and eliminate the spangle. Even though the zinc alloy lacks ductility and with severely formed parts, powdering of the surface sometimes occurs in localized areas, only the zinc coating comes off and a protective alloy bond remains. It will withstand temperatures in the range of 750°F without flaking. Except for normal cleaning, it can be painted without further surface preparation.
