This European Standard specifies requirements for continuously hot-dip coated products made of low carbon steels for cold forming, of steels for construction and of steels with high proof strength for cold forming coated with zinc (Z), zinc-iron alloy (ZF), zinc-aluminium alloy (ZA), aluminium-zinc alloy (AZ), aluminium-silicon alloy (AS) or zinc-magnesium alloy (ZM) and for continuously hot-dip coated products made of multiphase steels for cold forming coated with zinc (Z), zinc-iron alloy (ZF), zinc-aluminium alloy (ZA) or zinc-magnesium alloy (ZM) in thicknesses of 0,20 mm \u2264 t<\/i> < 3,0 mm.<\/p>\n
By agreement at the time of enquiry and order, this European Standard is applicable to continuously hot-dip coated flat products of an expanded validity range defined for thicknesses t < 0,20mm or in thicknesses 3,0 mm \u2264 t \u2264 6,5 mm with agreed mechanical properties and test specimens, adhesion of coating and surface condition requirements.<\/p>\n
The thickness is the final thickness of the delivered product after coating.<\/p>\n
This document applies to strip of all widths and to sheets cut from it (\u2265 600 mm width) and cut lengths (< 600 mm width).<\/p>\n
Products coated with (pure) aluminium can also be available, but are not covered by this European standard.<\/p>\n<\/div>\n
The products covered by this European Standard are used where cold formability, high strength, a defined minimum yield strength and\/or corrosion resistance are the most important factors. Corrosion resistance of the product is proportional to the coating thickness, hence to its mass (see also 7.3.2<\/span>). The products covered by this European Standard can be used as substrates for organic coated flat products specified in EN 10169<\/span> <\/span> for building and general engineering applications.<\/p>\n<\/div>\n By agreement at the time of enquiry and order, this European Standard is applicable to other continuously hot-dip coated hot rolled steel flat products (e.g. in accordance with EN 10149\u20112<\/span> <\/span>).<\/p>\n<\/div>\n Continuously hot-dip coated steel flat products for cold forming.
