Coil coatings first appeared in the 1930s and have developed significantly. The first major use of coil coating materials was to coat discharge lines, not as widely used today. In the 1950s and ’60s, it really started to gain widespread use.
In the beginning, the coil coating was done mainly by manpower. With the development of energy storage towers, the process has been fully industrialized. This makes it a very economical and efficient way to paint metal.
Film integrity and durability
The key elements of the color aluminum plate need to be kept flat and cleaned. Impurities on the surface will cause the adhesion of the coating to be reduced. One of the main properties of high-speed coil coated metal is its ability to form after coating. If you don’t have good adhesion, you can’t achieve that potential.
The coated paint has higher corrosion resistance
In addition to the beautiful appearance of the coating surface, it is also very resistant to corrosion. The surface coating can effectively resist ultraviolet rays and protect the inner metal. The corrosion resistance of aluminum itself is already very strong, so the corrosion resistance of coated aluminum coils is one of the most powerful materials. So, coated aluminum coils can be made for a variety of uses. Many household appliances, including refrigerators, air conditioners, use some form of pre-coated steel or aluminum in their construction. In the house decoration, is also a large number of users. Among them, the wood grain coating aluminum roll is used in house decoration.
