Iron zinc (IZ)

Iron zinc (IZ)

Iron Zinc is the result of a process that galvanises the metal followed by annealing. Annealing is a heat treatment that alters the physical properties of a material which increases its ductility and reduces its hardness, which makes it easier to shape. During the process the steel is heated above the recrystalisation temperature and then cooled. The galavanised steel sheet is heated until it glows and then allowed to slowly cool at room temperature.
