The ppgl color coated steel coils as the base plate, in addition to zinc protection, the organic coating on the zinc layer plays a covering and isolation function, which can prevent the steel plate from rusting, and has a longer service life than galvanized steel. Longer, according to incomplete research, the service life of ppgl color coated steel coils is 50% longer than that of galvanized steel sheets. However, in different regions and different areas of use, the service life of color coated plates with the same amount of galvanization, the same type of paint, and the same coating thickness will be very different.
For example, buildings or factories made of ppgl color coated steel coils often have a longer service life when they are washed by rain. Otherwise, the service life will be affected by the action of sulfur dioxide gas, salt and dust. Therefore, in the design, if the slope of the roof is larger, it is less likely to accumulate dust and other dirt, and the service life is longer; for those areas or parts that are not frequently washed by rain, they can be washed regularly with water.
The prepainted galvalume steel coil has the characteristics of pollution-free, excellent weather resistance, corrosion resistance and high processing. It is widely used in construction, home appliances, transportation, packaging, mechanical processing, interior decoration, medical treatment, automobile industry, etc. The approximate application ratio is home appliances: 31% Construction: 63% Others: 6%.
Color-coated sheets for construction generally use prepainted galvalume steel coil and hot-dip galvanized steel sheets as substrates, which are mainly processed into corrugated sheets or sandwich panels with polyurethane composites, and used for the construction of steel structure workshops, airports, warehouses, and freezers. Roofs, walls and doors of industrial and commercial buildings. Color-coated panels have been widely used in the construction industry. More and more builders use color-coated panels to establish their own good reputation. You can use them in many large shopping malls and industrial facilities, hotels, restaurants, resorts, and farms. In buildings, office buildings and sports facilities, we see a large number of applications of color-coated board products.
