Abstract
In a ferrous product with a metal coating having improved corrosion resistance, the surface coating is in stratified form with nodules (zone 3) of an Fe-Al-Zn compound comprising between 60 and 70 % iron, 20 to 25 % aluminium and the remainder zinc in an iron-zinc-aluminium matrix (zone 2) comprising 10 to 15 % iron and less than 3 % aluminium.
