Aluminum skin sheets for trailer are usually made of 3003 H14 aluminum with white color painted. The material requirements of the trailer skin panel can be divided into safety performance - impact resistance, wind pressure resistance, fire resistance, living performance - waterproof, heat insulation, sound insulation, durability - anti-pollution, weather resistance, appearance retention, production and processing performance - economical, easy to process, easy to maintain, easy to repair.
Aluminum skin sheets for trailer are welcomed in trailer and caravans manufacturing industry, because aluminum sheet material has good corrosion resistance, good ductility, light weight and long service life. However, its price is relatively high, and it is generally used in some parts of the vehicle, and some are used for the loading of the whole vehicle, such as the body of a trailer, the body of a tanker, etc. For the ultimate owner of the trailer, the safety and longevity of white painted aluminum sheets for trailer are of the most importance. For the design unit, the service life, bearing capacity and appearance are more important. For the building trailer and caravan industry, the processing of white color coated aluminum sheets, surface hardness, abrasion resistance, sheet shape and sheet strength are the preferred requirement. Of course, the quality of the white color-coated trailer aluminum sheet mainly depends on the color coated aluminum sheet manufacturer, but if the processing and installation equipment and methods are improper, the appearance and service life of the final product will be damaged to varying degrees.
What are the performance indicators of the painted aluminum skin sheets for trailer?
1, Substrate: Yield strength, tensile strength, elongation;
2, Coating: coat weight, adhesion;
3, Coating: color difference, gloss, T-bend, impact, hardness, chalk resistance, heat resistance, moisture resistance, etc.
4, Surface: visible surface defects;
5, Flatness: Tolerance, Inequality.
