High Gloss White Color Coated Aluminum 2600mm Width Used For Truck Body Manufacturer
Color coated aluminum (prepainted aluminum),which is produced with aluminum sheet or coil and processed by coating with color or pattern.
In common sense, here are two kinds of coating PVDF and PE.Compared with other section steel prepainted aluminum coil is the more popular material, because of its excellent property. Firstly the property is very stable so the surface is erosion resistant, warranty could up to 30 years long after special treatment. Then,the density is the lowest among metal material when volume is fixed.
