a large number of galvanized sheet plate used in automobile manufacturing, cooler, construction, ventilation and heating facilities and furniture manufacturing and other fields. Galvanized become important steel anticorrosion method, not only because the zinc can be formed in the steel surface protective layer of dense, but also because of the zinc has the effect of cathodic protection, when the galvanized layer damaged, it can still through the cathodic corrosion protection to prevent the iron base. 0.12-5.0MM*600-1250MM Galvanized Construction industry: roof, roof components, panels, balcony window, newsstands, warehouse, rolling door, heaters, drainage, etc . Galvanized Steel Coil With 30-275g/M2 Zinc Coating Household appliances: refrigerators, washing machines, switch cabinet, air conditioning, microwave oven, bread machine, copier, vending machines, electric fans, vacuum cleaners, etc. Furniture industry: lampshade, wardrobe, desk, bookcase, counter, signs, medical equipment, etc Transportation industry: cars, car shell, carriage board ceiling, tractor, trams, container, highway fence, ships bulkhead, etc. Other instrument shell, dustbin, billboards, clocks, photographic equipment, meter and other hot galvanized steel sheet, color coating steel plate is hot aluminium zinc plate, electric galvanized sheet as the substrate, such as the surface pretreatment.Nowadays, the main automotive steel sheets in the market are Chinese GI Steel Manufacture, and now many of the products are also Chinese GI Steel Manufacture. 1. Why should we use Galvanized Steel Coil With 30-275g/M2 Zinc Coating first? First, the Galvanized Steel Coil With 30-275g/M2 Zinc Coating is a zinc layer coated with a certain thickness on the steel sheet to improve corrosion resistance. Since the 1970s, the car body steel plate has been galvanized steel sheet. When assembled, the galvanized surface is placed on the inside of the car to improve the corrosion resistance of the car body. The non-galvanized surface is placed on the outside of the car and sprayed with paint. Zinc plating has become an important method of steel corrosion protection, not only because zinc can form a dense protective layer on the steel surface, but also because zinc has a cathodic protection effect. When the galvanized layer is damaged, it can still prevent iron mother by cathodic protection. Corrosion of materials. 2, galvanized coil plate features high load-bearing capacity, light weight and easy to hoist, etc., beautiful appearance, long-lasting ventilation: hot dip zinc surface treatment makes it have a good anti-corrosion ability, surface gloss and beautiful; ventilation, lighting, heat dissipation, explosion-proof, Good anti-slip performance; anti-staining. Widely used in power grids, water plants, sewage treatment plants, petrochemical municipal engineering, sanitation engineering and other fields of steel grating platform, steel grating aisle, trestle, ditch cover, manhole cover, ladder, fence, guardrail and so on. 3, the use of galvanized coils galvanized coils are mainly used in the industry: a large number of galvanized thin sheets for automotive manufacturing, reefer, construction, ventilation and heating facilities and furniture manufacturing. Construction industry: roofs, roofing components, balcony panels, window sills, kiosks, warehouses, rolling doors, heaters, rainwater pipes, etc. Household appliances: refrigerators, washing machines, switch cabinets, air conditioners, microwave ovens, bread machines, copiers, vending machines, electric fans, vacuum cleaners, etc. Furniture industry: lampshades, wardrobes, tables, bookshelves, counters, signboards, medical equipment, etc. Transportation industry: car ceilings, car shells, car panels, tractors, trams, containers, highway walls, ship bays, etc. Other aspects: The color coated steel plate such as musical instrument casing, garbage bin, billboard, clock, photographic equipment, meter, etc. is made of hot-dip galvanized sheet, hot-dip aluminum-zinc plate, electro-galvanized plate, etc.0.12-5.0MM*600-1250MM Galvanized type: hot galvanized steel sheet, electric galvanized sheet, including electrolytic tinplate, galvanized sheet pressing and forming, with a connection, do not need any accessories can firmly connect the mesh and the pillar is firm. Galvanized sheet according to its use can be divided into: activated alumina galvanized sheet, desiccant galvanized sheet and catalyst galvanized sheet. The chamber is made of high quality galvanized sheet or stainless steel plate in the working chamber clean the rust.Different types of galvanized sheet price is also different, different industries, of course, use galvanized sheet price and material is different, so you in choosing a galvanized sheet, you must provide a sale purpose, so that they will come through your purpose for you to choose more suitable your product.1. Passivation A chemical treatment used for the galvanized layer. It can reduce the rust (white rust) caused by moisture during storage. It is the most common surface treatment method for galvanizing layer except for the finishing surface. 2. Oiling The surface treatment to reduce the occurrence of rust on steel plates under wet storage conditions. The passivated steel sheet is usually oiled again. 3. Normal Zinc Flower Zinc in the normal solidification process, the zinc crystal grains grow freely and can be clearly recognized by the naked eye. 4. Small zinc flower During the solidification process, zinc crystallites are restricted to form zinc flowers smaller than normal zinc flowers. 5.No zinc flower By adjusting the chemical composition of the plating solution, there is no visible zinc flower morphology and a uniform coating on the surface. 6.Finishing zinc flower Uniform surface coating obtained after cold rolling of a small amount of deformation on the steel sheet.
