ASNSWER: A463 EDDS is a Hot dip Aluminized steel material grade under ASTMA463/A463M standard.
Different from the European standard Aluminized steel, A463 EDDS coating has two types. One is AS coating type (95%-89% Al + 5%-11% Si ) ; the second is Pure Aluminium coating.
A463 EDDS Coating masses (g/m2): T1M40, T1M75, T1M120, T1M300, T2MLC, T2M200, T2M300
However the Surface treatment are C,O, Dry
