How to Find A Best Color Coated Coil Manufacturer in China
According to the customs data, the export volume of the color coated coils keep increasing every year. If you are one of them or want to buy painted aluminum coils from China, there is a key question for you: how to find a best color coated coil manufacturer in China.
The author of this page has one suggestion for you: To have a basic knowledge of the manufacturing process of color coated coil. The coating process mainly has two kinds: the spraying coating and the roller coating process.
Spraying Coating
The thickness and alloy model of the spraying coil can be selected according to the design needs, without being limited by the process. The standard commonly used at home and abroad to measure the performance of the PVDF coatings on the surface of aluminum sheet is the AAMA 605.2 specification issued by American Building Manufacturers Association. The colour coated coil that is widely for curtain walls usually adopt this coating process.
Roller Coating
Due to the characteristics of the roller coating process, the thickness of the roller coating plate is not more than 2.5mm. Its coating thickness is usually less than less than 251xm. The thin coating will reduce its UV 
penetration resistance and wind erosion resistance. In order to achieve a thickness of 401xm, the roll-coated sheet has to be coated and baked multiple times. In this way, the layer-to-layer molecular binding force is lower than that of the internal molecular, which is easy to be corroded.
The Best Color Coated Coil Manufacturers
In terms of the processing, the spraying processing is better. When you really buy, multiple factors will influence your choice like application and price. The proper choice is the best one. At present, many color coated coil manufacturers can do PVDF powder coated aluminum coil. Haomei Alu is one of them.
