For galvanized coils, the sheet steel is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also manufactured by hot dip method, but immediately after being out of the tank, it is heated to about 500 ºC to form an alloy coating of zinc and iron. This galvanized coil has good paint adhesion and weldability.
Product use: The coated steel plate has light weight, beautiful appearance and good corrosion resistance, and can be directly processed. It provides a new type of raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, furniture industry, electrical industry, etc. Substituting steel for wood, efficient construction, energy saving, pollution prevention and other good effects. The color-coated steel plate using galvanized steel plate as the substrate, in addition to zinc protection, the organic coating on the zinc layer plays a role of covering and isolation, which can prevent the steel plate from rusting, and its service life is longer than that of the galvanized steel plate.
According to reports, the coating The service life of steel plate is 50% longer than that of galvanized steel plate. However, in different regions and different parts of use, the service life of color-coated sheets with the same amount of galvanizing, the same coating, and the same coating thickness will be very different. For example, in industrial areas or coastal areas, due to the effect of sulfur dioxide gas or salt in the air, the corrosion rate is accelerated and the service life is affected. In the rainy season, if the coating is soaked by rainwater for a long time, or the parts where the temperature difference between day and night is too large and easy to condense, will be corroded quickly, and the service life will be reduced. Buildings or workshops made of color-coated steel plates have a long service life when they are often washed by rainwater, otherwise, they will be affected by the action of sulfur dioxide gas, salt and dust. Therefore, when designing, if the inclination of the roof is larger, it is less likely to accumulate dust and other dirt, and the service life will be longer; for those areas or parts that are not frequently washed by rainwater, they should be washed with water regularly.
Applications of color-coated steel sheets: Construction (outdoor) workshops, agricultural warehouses, residential prefabricated elements, corrugated roofs, walls, rainwater pipes, balcony railings, newsstands, cold storages, kiosks, rolling shutters Construction (indoor) doors, Door frames, house light steel structures, screens, ceilings, elevators, stairs, ventilation ducts, electrical appliances, refrigerators, washing machines, switch cabinets, instrument cabinets, air conditioners, microwave ovens, bread machine furniture radiators, lampshades, wardrobes, tables, beds, dressing boxes, Bookshelf transportation industry, interior decoration of automobiles and trains, partitions, containers, partitions, ship partitions, other whiteboards for writing, garbage cans, billboards, clocks, typewriters, dashboards, weights, photographic equipment

Description |
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. Galvanized 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. |

Strip steel is a kind of narrow and long steel plate produced by various steel rolling enterprises in order to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. Strip steel, also known as steel strip, is within 1300mm in width and slightly different in length according to the size of each roll.
Steel plates with thin thickness, narrow width and long length. Its width is generally 20mm-200mm. It is supplied in rolls, and its specifications are expressed as thickness × width. According to the quality of the steel, it is divided into high-quality and ordinary strip; according to the rolling method, it is divided into hot-rolled and cold-rolled, which are called hot-rolled strip and cold-rolled strip respectively. The thickness of hot-rolled ordinary strip is 2 mm-6 mm, and the thickness of cold-rolled strip is generally 0.05 mm-3.60 mm. Strip steel can be made of ordinary carbon steel, carbon structure steel, spring steel, tool steel, stainless steel and other steel grades. Widely used in the manufacture of welded pipes, clamps, gaskets, spring blades, saw blades, blades, etc.
Strip steel is generally supplied in coils, which have the advantages of high dimensional accuracy, good surface quality, easy processing, and material saving.
The production process of cold-rolled strip steel is generally: pickling → rolling → process lubrication → annealing → leveling → shearing → packaging.
Cold-rolled strip steel process: pickling - rolling - annealing - rolling size synchronization lubrication - anti-rust oil - leveling and sizing - polishing - packaging
Hot-rolled strip process: heating furnace - dephosphorization machine - rough rolling mill - dephosphorization machine - finishing mill - surface quality tester - layer cooling - coiling machine - baler - spray number Machine - roll warehouse slab
Hot-rolled strip production process: first, the temperature is raised to the required rolling temperature in the heating furnace, and then enters the rough rolling dephosphorization machine through the roller table to process the iron oxide scale produced by the slab, and then enters the rough rolling mill. Roll the width and thickness of the strip, and then transport it from the roller table to the finishing rolling dephosphorization machine to process the iron oxide scale produced on the surface of the strip, and then enter the finishing rolling mill to change the thickness and width of the strip. For precise rolling, the strip steel is strictly controlled by the roller table to control the surface temperature before coiling, and then enters the coiler to become the steel coil.
