The white painted aluminium sheet is a common product of HC Aluminum color coated aluminum sheet coil. The white color of painted aluminum sheet is welcomed on the market, while used for making shutter, rolling door, trailer side and roofing, ceiling, vehicle licence plate, channel letter, composite panel and so on.
The quality of white painted aluminium sheet are represented by substrate and painting.
1, Substrate
When purchasing white painted aluminum sheet, the aluminum grades are often considered according to the design requirements, because the aluminum grades relate to the building's bearing weight, span and purlin distribution requirements. In short, users of painted aluminum sheet pay more attention to the strength of the material, and the designer will also consider the balance between safety and economy. The strength of the color coated aluminum sheet depends on the substrate, so its strength can refer to the situation of the substrate, but the final choice depends on the design requirements, especially the corresponding yield strength, tensile strength, elongation and other indicators. Like most aluminum product, coated aluminum sheet is also developing towards higher strength.
2. Coating
The thickness of the coating is the most important guarantee condition for corrosion resistance. The greater the thickness of the coating, the better the corrosion resistance, which has been proved by many accelerated tests and exposure tests. Therefore, we recommend that customers pay special attention to the thickness of the coating when purchasing coated products, which will determine the service life of the white painted aluminium sheet. Appropriate materials can greatly reduce your cost of use. No matter it is PE white painted aluminum sheet or PVDF white painted aluminum sheet, the thickness of coating on painted aluminium sheet should be considered.
