Product Description Product DescriptionGalvanized steel plate is a welded steel plate with hot dip plating or electric galvanized layer on the surface, which is generally widely used in construction, home appliances, vehicles and vessels, container manufacturing, electromechanical industry and so on.Galvanized steel is mild steel with a coating of zinc. The zinc protects the steel by providing cathodic protection to the exposed steel, so should the surface be damaged the zinc will corrode in preference to the steel. Zinc steel is one of the most widely used products, used extensively in the building sector, automotive, agricultural and other areas where the steel needs to be protected from corrosion.Product NameGalvanized Steel SheetStandardASTM,AISI,SUS,JIS,EN,DIN,BS,GBMaterialDC51D,DX51D,DX52D,DX53D,DX54D,SGCC,SGCD,SGHC,S350GD,S450GD,S550GDSurface treatmentChromated/non-chromated,oiled/non-oiled,skin passThickness0.12-4.0mmWidth20-1250mmSurface treatmentChromated/Non-Chromated, Oiled/Non-oiled, Skin passApplicationConstruction field, ships building industry, petroleum & chemical industries, military and electricity industries, food processing and medical industry, boiler heat exchange,machinery and hardware fieldsDetailed PhotosProduct ParametersThe manufacturing process of galvanized sheets is generally divided into the following steps:1.Surface treatmentFirst, the surface of the substrate needs to be treated to remove oil, rust and other impurities on the surface tofacilitate the subsequent adhesion of the coating.2. Pickling treatmentNext, pickling treatment is required to remove the iron oxide scale on the surface of the substrate and enhancethe adhesion of the substrate surface.3. Immersion plating treatmentThe pickled substrate is immersed in a plating solution containing zinc salt, and after an electrochemical reaction,a zinc layer is deposited on the surface of the substrate to form a zinc plating layer.4. Drying treatmentThe galvanized sheet is dried to remove moisture and volatile matter from the surface, making the galvanizedlayer stronger.5. Coating treatmentIf necessary, the surface of the galvanized sheet can be coated to increase the durability and aesthetics of its surface.Galvanized sheet Steel SheetGalvanized sheet refers to a steel sheet with a layer of zinc on the surface. Galvanizing is a commonly used economic method to prevent the surface of the steel sheet from corrosion and extend its service life. A layer of metal zinc is coated on the surface of the steel sheet. This zinc-coated steel sheet is called a galvanized sheet. It is an effective anti-rust method. About half of the world's zinc production is used in this process.Due to different treatment methods in the coating process, the surface state of galvanized sheets is also different, such as ordinary zinc spangles, fine zinc spangles, flat zinc spangles, no zinc spangles, and phosphating surfaces. German standards also stipulate surface levels. Galvanized sheets should have a good appearance and should not have defects that are harmful to the use of the product, such as no plating, holes, cracks, scum, excessive plating thickness, scratches, chromic acid dirt, white rust, etc. Foreign standards are not very clear about specific appearance defects. Hot-dip galvanizing processHot-dip galvanizing is to immerse the steel material in molten zinc liquid so that a layer of zinc is attached to its surface. This process includes the following steps:Pretreatment: Clean and degrease the steel surface to ensure that the zinc layer can be firmly attached to the steel.Dip plating: Immerse the treated steel in molten zinc liquid, and the zinc in the zinc liquid reacts with the steel to form an alloy layer.Cooling and solidification: The workpiece after dip plating needs to be cooled and solidified to form a continuous zinc layer.Post-treatment: Trim and inspect the galvanized workpiece to ensure that the quality meets the requirements Electrogalvanizing (cold galvanizing)The process of depositing a layer of zinc on the surface of steel through the principle of electrolysis. The specific steps are as follows:Electrolyte preparation: Prepare an electrolyte containing zinc ions.Electroplating: Use steel as the cathode, and through the action of electric current, zinc ions are reduced to metallic zinc on the surface of steel to form a coating.Post-treatment: After electroplating, clean and dry the workpiece to ensure that the coating is uniform and flawlessPackaging & ShippingMultiple packing:wooden case,wooden pallet or waterproof woven bag.Plywood case packing:high resistance of burst strength,ring crush strength and tearing strength.Wooden frame packing:damp-proved and high resistance of burst strength ring crush strength.
