EN 10346 specifies requirements for continuously hot-dip coated products made of low-carbon steels for cold forming, steels for construction, and steels with high proof strength for cold forming, coated with zinc (Z), zinc-iron alloy (ZF), zinc-aluminium alloy (ZA), aluminium-zinc alloy (AZ), zinc-magnesium alloy (ZM), aluminium-silicon alloy (AS) or aluminium (A).
It also specifies requirements 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 ≤ t ≤ 6,5 mm.
By agreement at the time of enquiry and order, EN 10346 applies to continuously hot-dip coated flat products of an expanded validity range defined for thicknesses t < 0,20 mm with agreed mechanical properties and test specimens, adhesion of coating and surface condition requirements. This standard is applied to strip of all widths and to sheets cut from it (≥600 mm width) and cut lengths (<600 mm width).
The products covered by EN 10346 are used where cold formability, high strength, a defined minimum yield strength or corrosion resistance are the most important factors. Corrosion resistance of the product is depending on coating type and coating thickness, hence to its mass. The products covered by this standard can be used as substrates for organic coated flat products specified in EN 10169 for building and general engineering applications.
