Product description:
Galvanized steel coil, immersing the thin steel plate in the molten zinc bath, adhering a layer of zinc thin steel sheet on the surface.It is mainly produced by continuous galvanizing process, that is, the coiled steel plate is continuously immersed in the zinc-melted plating tank to make galvanized steel sheet; alloyed galvanized steel plate. This kind of steel plate is also made by hot dipped method, but it is heated to about 500 ° C immediately after exiting the tank to form an alloy film of zinc and iron.This galvanized coil has good paint adhesion and weldability.
Product description:
Galvanized steel panels are coated with a layer of metallic zinc on the surface to prevent corrosion on the surface of the steel panels and extend their service life. This zinc-coated steel panel is called a galvanized panel.
Application:
The main application industries of galvanized sheet: a large number of galvanized sheets are used in automobile manufacturing, refrigerated containers, construction, ventilation and heating facilities, and furniture manufacturing. Galvanizing has become an important method of steel corrosion protection, not only because zinc can form a dense protective layer on the surface of steel, but also because zinc has a cathodic protection effect. When the galvanized layer is damaged, it can still prevent iron mother by cathodic protection Wood corrosion in the construction industry: roofs, roof components, balcony panels,window sills,newsstands, warehouses, rolling shutters, heaters, rainwater pipes, etc.
Household appliances: refrigerators, washing machines, switch cabinets, air conditioners, microwave ovens, bread machines, photocopiers, vending machines, electric fans, vacuum cleaners, etc. Furniture industry: lampshades, wardrobes, tables, bookshelves, counters, signs, medical equipment, etc.
Transportation industry: car ceilings, car shells, compartment panels, tractors, trams, containers, highway walls, ship bulkheads, etc.
Other aspects:
Color-coated steel plates such as musical instrument shells, trash cans, billboards, clocks, photographic equipment, meters, etc. are made of hot-dip galvanized sheet, hot-dip galvanized sheet, electro-galvanized sheet, etc. as substrates, and are made by surface pretreatment.
