(Main)Continuously hot-dip coated strip and sheet of structural steels - Technical delivery conditions
General Information
- Abstract
1.1 This European Standard specifies requirements for continuously hot-dip coated products made of structural steels 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 from 0,35 mm up 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 minimum yield strength 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).
NOTE +ZF coated products should not be used without additional organic coating.
1.4 This European Standard is not applicable to:
· continuously hot-dip coated flat products of low-carbon steel strip and sheet for cold forming (see prEN 10327);
· electrolytic galvanized cold rolled steel flat products (see EN 10152);
· continuously organic coated (coil coated) flat steel 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).

7.2 Mechanical properties 7.2.1 The products shall be supplied on the basis of the mechanical property requirements in Table 1. 7.2.2 lf so agreed at the time of enquiry and order, products specified in Table 1 may be supplied with suitability for manufacturing a specific part. In this case the values given in Table 1 do not apply. The reject tolerances arising when the material is processed shall not exceed a specific proportion to be agreed at the time of enquiry and order. 7.2.3 A reduction in the formability of all the coated products specified in this standard may occur by ageing. Therefore it is in the interest of the user to use the products as soon as possible after receiving them. 7.2.4 The tensile test values apply to longitudinal test pieces and are related to the test piece cross section without coating.
