Painted Aluminum Sheets Factories

Painted aluminum sheets factories supply high quality color coated aluminum material with alloy A1100, A3003, A3004, A3105. Color coated aluminum sheet is a roller coating method, which applies paint to the surface of an object to form a dry protective film on the surface of the color painted aluminum sheet to make it resistant to corrosion and pollution, thereby protecting the substrate and imparting color, luster, pattern, smoothness, three-dimensional effect at the same time, make the building beautiful. The gloss retention is high, the color stability is good, and the color difference change is minimal. Polyester paint is guaranteed for 10 years, and fluorocarbon paint is guaranteed for more than 20 years.

When joined the color coating industry. At that time, the color of the painted aluminum sheets factories was relatively single. The most common ones were crimson, sea blue and white gray, the three main color systems. Throughout the country, most of the building metal enclosures are either blue-roofed and white walls, or red-roofed and white walls, and the coating types are basically ordinary polyester. Nowadays, although crimson, sea blue and white gray are still more commonly used colors of painted aluminum coil, they account for less and less. A large part of them has been replaced by silver, gold, orange, green, purple and other colorful colors. Traditional polyester coatings are increasingly being replaced by various functional coatings such as high weather resistance, fluorocarbon, antibacterial, antistatic, thermal insulation, anti-scratch, mesh, and sand patterns. The base material has also changed from a single galvanized sheet to multiple base materials such as galvanized zinc, galvanized aluminum-magnesium, stainless steel, aluminum sheet, and titanium zinc sheet.

When the color coated aluminum sheet is used, it may be directly or partially exposed to the atmospheric environment. When selecting materials, painted aluminum sheets factories need to consider the corrosion of the external atmospheric environment. In addition, it may also be used in a relatively closed environment. At this time, it is necessary to consider the corrosion of the internal atmosphere. According to different corrosion environments, when selecting materials for color-coated sheets, a targeted anti-corrosion design should be done, including the thickness of the steel plate, the type of zinc layer, the weight of the zinc layer, the type of coating, the structure of the coating, and the thickness of the coating.
