Galvanized steel coilHot-Dip Galvanizing or HDG is a process in which zinc bonds to steel at the molecular level to produce a four-layer corrosion-resistant finish. The first three layers are zinc-iron alloy layers that are actually harder than the base steel. The fourth or top layer is pure zinc.The Specification of galvanized steel coilsCommodityGalvanized steel coilTechinical StandardDX51D / DX52D/ DX53D/ SGCC/DC51D+Z/SGC250/SGC350/CS type A/B/C/St01ZStandardAISI, ASTM, BS, DIN, GB, JIS, etcSurfaceChromated(Cr6)Chromated(Cr6) and oiledCr3 Chromated(Environmental)Cr3Chromated(Environmental) and oiledEnvironmental passivated( Chrome free) and oiledSkin passedoiledEnvironmental passivated( Chrome free)Non-treatmentSurface treatmentZinc coatingSpangleRegular spangle,min spangle,big spangle,zero spangleID coil508mm or 610mmCoil weight3-8 MT per coilPackageProperly packed for ocean freight exportation in 20''containersThickness0.14-4.5mmWidth30mm-1500mm as customizedLengthIn coil or in sheet as customized lengthAluzinc coating30-275gsm both sideMeterial typeCommercial quality or high strengthPlace of originChinaSupply ability50000 tons per monthPackageStandard seaworthy export packing: 3 layers of packing, inside is kraft paper, water plastic film is in the middle and outside GI steel sheet to be covered by steel strips with lock, with inner coil sleeveMOQIn stock 1ton, or 25tonsPaymentTT/LC/DP/OAThe detail of galvanized steel coilsSurface treatment of galvanized steel coilUsage of galvalume steel coilInfrastructure: Roofing; External Siding; Garage; ShutterHousehold Appliances: Oven; Air-Conditioning Ventilation System; Solar Water Heater; Electronics;Automobile: Mobile Muffler; Vent Pipe; Catalysis Converter Heater Shield; Bottom Accessories;Industrial Instrument: Electric Control Cabinet; Industrial Freezer Chest; Dispenser;Package of galvanized steel with edge protector. steel hoop and seals, or as per requirements of customers.Package:
