1A = Clear Passivate
1B = Bleach
2C = Colour Passivate
2D = Drab Olive Passivate Note: unavailable in trivalent passivate


Note: After Fe Zn a Number is given known as thickness codes to represent the thickness of Zinc in microns i.e. Zn5 Zn8 Zn12 etc. Example of full coating classification: Zinc plate to BSEN12329:2000 Fe Zn8 1A which means; FE = Ferrous substrate, ZN = Zinc coating 8 μm min deposit and 1A = Clear passivate.
