Application: The coated steel plate has light weight, beautiful appearance and good anti-corrosion performance, and can be directly processed, it provides a new raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, furniture industry, electrical industry and so on, has played a steel instead of wood, efficient construction, energy saving, prevent pollution and other good effects. Use galvanized steel plate for the color coating steel plate base plate, in addition to zinc protection, the organic coating on the zinc layer has the effect of covering isolation, can prevent steel plate rust, service life is longer than galvanized steel plate, according to the service life of coating steel plate is 50% longer than galvanized steel plate. But, be in different area and different use place, use the chromatic coating board of thickness of same galvanizing quantity, same coating, same coating, its service life can have very big different. For example, in industrial areas or coastal areas, due to the action of sulfur dioxide gas in the air or salt, the corrosion rate is accelerated and the service life is affected. In the rainy season, the coating is soaked by rain for a long time, or in the part of the day and night temperature difference is too large easy to dew, will be quickly corroded, the service life will be reduced. Buildings or factories made of colored coated steel plates often have a long service life when they are washed by rain, otherwise they will be affected by sulfur dioxide gas, salt and dust. Therefore, in the design, if the greater the tilt of the roof, it is not easy to accumulate dust and other dirt, the longer the service life; For those areas or parts that are not frequently washed by rain, water should be washed regularly. Application of color coated steel plate: Construction (outdoor) plant, agricultural, residential prefabricated warehouse, corrugated roof, wall, rain water piping, balcony railing, kiosks, cold storage, cargo sale booth construction (indoor), shutter door, door frame, light steel structure housing, screen, ceiling, elevators, stairs, ventilation electrical appliances refrigerators, washing machines, Switch cabinet, instrument ark, air conditioning, microwave oven, toaster furniture radiator, chimney, wardrobe, table, bed, locker, bookshelf transportation, cars and trains in decoration, baffle plate, container board, police, ships across the storehouse Other to write on the whiteboard, dustbin, billboards, clocks, typewriter, dashboard, body weight, photographic equipment.
