[1] The galvanising bath contains slightly over 0.1% aluminium, added to form a layer bonding between the iron and coated zinc.
From the steel boundary these are named the Gamma (Γ), Zeta (ζ), and Delta (δ) layers, of compositions Fe3Zn10, FeZn10, FeZn13 respectively; resulting in an overall bulk iron content of 9-12%.
