Product DescriptionGalvanized steel is to prevent surface from corrosion and prolong the service life of the steel surfaces, coated with a layer of metal .zinc the king of zinc coated thin plate called galvanized sheet.Hot-dip galvanized is hot - rolled steel coils, or cold-rolled steel as a substrate, after a continuous hot-dip galvanized process and then produced. The cross-section to a rectangular plate which for supply is hot dip galvanized sheet; by the take -up in order to supply hot roll galvanized volumes. Therefore, hot-dip galvanizing can be classified into hot-rolled coils galvanized coils and cold rolled coils, which are mainly used in construction, housed hold appliances, automobiles, container, transport and family business and other fields, in particular, steel construction, automobile manufacturing, steel silo manufacturing and other industries.Detailed PhotosSome detailed pictures about the organic coating on the surface of galvanized steel coil Product ParametersProduct Name Hot dipped cold rolled electro zinc coat galvanized steel coil MaterialQ235, Q345, Q195, Q215, St37, St42, St37-2, St35.4, St52.4, ST35Thickness0.13mm TCT up to 4.0mm TCT.Width50mm-2000mm or customized Zinc CoatingZ40g-Z275gSurface SurviceRegular spangle,Minimum spangle, Zero spangle, Big spangleStandard JIS G 3302, ASTM A653, EN10346, AS1397, DIN, GB2518Steel gradeSGCC, SGC340-490, SG220GD-SG350GD, DX51D+Z, DX52D+Z, G250-G450  Factory  ApplicationsBuilding & Construction:Roofing; Terrace; Window Frame;Door:Rolling-up Door; Shutter; Mobile House;Interior Decorations:Wall; Door Frame; Steel Structure; Screen; Ceiling;Elevator;Household Appliances:Fridge; Washing Machine; Microwave Oven; Air-Conditioner; Duplicating Machine,etc;Transportation:Auto Panel; Interior Decorative Panel; Carriage Panel;CertificationsPackaging & ShippingAfter the production is over, we will first list the finished products in the warehouse, and the professional quality inspection master will conduct quality inspection on the galvanized steel coil.
