1.1 This European Standard specifies requirements for continuously hot-dip coated products made of low carbon steels for cold forming coated with zinc (Z), zinc-iron alloy (ZF), zinc-aluminium alloy (ZA), aluminium-zinc alloy (AZ) and aluminium-silicon alloy (AS) (see Table 1) with thicknesses of 0,35 mm to 3,0 mm unless otherwise agreed (see 1.2). 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).
1.2 If agreed at the time of enquiry and order, this European Standard may also be applied to continuously hot-dip coated flat products in thicknesses > 3,0 mm. In this case the mechanical property, adhesion of coating and surface condition requirements shall also be agreed at the time of enquiry and order.
1.3 The products covered by this European Standard are mainly used where cold formability and corrosion resistance are the most important factors. Corrosion resistance of the alloy is proportional to the coating thickness, hence to its mass (see also 7.3.2).
1.4 This European Standard is not applicable to:
· continuously hot-dip coated structural steel flat products (see prEN 10326)
· electrolytically zinc coated cold rolled steel flat products (see EN 10152)
· continuously organic coated (coil coated) steel flat products (see EN 10169-1, ENV 10169-2 and
EN 10169-3)
· continuously hot-dip coated strip and sheet of steels with higher yield strength for cold forming (see EN 10292).
