Continuously hot-dip coated strip and sheet of steels with high yield strength for cold forming - Technical delivery conditions
This European Standard specifies requirements for continuously hot-dip zinc (Z), zinc-iron alloy (ZF), zinc-aluminium alloy (ZA), aluminium-zinc alloy (AZ) and aluminium-silicon alloy (AS) coated flat products made of steels with high yield strength for cold forming (see Tables 1 and 3) with thicknesses up to and including
3,0 mm unless otherwise agreed. The thickness is the final thickness of the delivered product after coating.
This European Standard applies to strip of all widths and to sheets cut from it (? 600 mm width) and cut lengths (< 600 mm width).
The products covered by this European Standard are mainly used where cold formability and corrosion resistance for a defined minimum yield strength are the most important factors.
