Product Description
HDG coils according to European and Ukrainian standards
Galvanised steel coils as per the European EN 10346 and the similar Ukrainian DSTU EN 10346 standards can be coated with zinc, zinc-iron alloy, zinc-aluminium alloy, aluminium-zinc alloy or aluminium-silicon alloy:
Zinc coating (Z) is achieved by dipping the prepared strip into a bath with molten alloy, containing at least 99% zinc. This is the most common and traditional way of protecting rolled steel from corrosion.
Zinc-iron coating (ZF) is formed by dipping a strip into a bath of molten zinc (at least 99% zinc) with further annealing to form a zinc-iron coating with an Fe content of 8-12%. Such coating is stronger than the traditional zinc coating and has better adhesion with substrate steel due to mutual diffusion between the iron and zinc in the surface layers. That is why this coating is less exposed to lamination or pitting under impact, mechanical stresses or deformation of treated products.
Zinc-aluminium coating (ZA) is applied to rolled steel by dipping it into a bath of zinc and about 5% aluminium with a minor content of mishmetal (mix of metals). Rolled steel with such coating has better formability and corrosion protection properties compared with zinc-coated steel.
Aluminium-zinc coating (AZ) is applied by dipping steel into a bath of molten metal consisting of 55% aluminium and 1.6% silicon (with the remaining being taken up by zinc). The combined action of these metals ensures the best corrosion protection compared with other coatings.
Aluminium-silicon coating (AS) is created by dipping steel into a bath of molten metal containing aluminium and 8-11% silicon. Galvanized steel coil with such coating is highly resistant to oxidation at high temperature (up to 650°C) and highly resistant to chemical corrosion.
Galvanised steel coils manufactured according to the EN 10346 and DSTU EN 10346 standards can be made from the following steels:
Low-carbon steel for cold forming (DX51D - DX57D). These products are classified based on suitability for cold forming: DX51D - bending and profiling quality; DX52D - drawing quality; DX53D - deep-drawing quality; DX54D - special deep-drawing quality; DX55D - special deep-drawing quality (only +AS); DX56D - extra deep drawing quality; DX57D - super deep drawing quality.
Steel for construction and framing (S220GD - S550GD). Rolled products are arranged in increasing yield stress (Rp0.2), which is indicated in the marking. Rolled products of S220GD - S550GD steel are mainly used in the manufacture of formed sections (Z-, C-, sigma-, U-shaped profiles, etc) for light-gauge steel structures.
Steel with high yield strength for cold forming (HX160YD, HX180YD, HX180BD, HX220YD, HX300LAD, etc). Such rolled products are arranged in increasing yield stress (Rp0.2), which is indicated in the marking. The marking also contains the following information: H - high-strength flat rolled products for cold forming; Х - as-rolled condition (hot-rolled or cold-rolled) is not defined; D - designed for hot-dip coating; B - heat-treated steel; Y - steel with higher formability; LA - low-alloy / micro-alloy steel.
Cold-formable multi-phase steel (HDT450F, HCT490X, HDT590X, HCT780X, HCT980X, HCT780T, HDT580X, etc). Rolled products are arranged in increasing minimum tensile strength (Rm0.2), which is indicated in the marking. The marking also contains the following information: H - high-strength flat-rolled products for cold forming; С - cold-rolled products; D - hot-rolled products; Т (nnn) - the minimum tensile strength in MPa. The last symbol: F - ferrite-bainite, Х - dual-phase; Т - TRIP, С - complex-phase; М - martensite.
