The thickness of the coloured aluminium sheet is mainly related to the coating equipment. The usual coating equipment can process the color coated aluminum coil with a thickness of 0.3-1.2mm. The coloured aluminum sheet with this thickness can meet most of the application, so this is the common used thickness. Haomei Aluminum supply color coated aluminum coils of various thicknesses, and non-standard sizes and widths can be customized. At present, we can provide color coated aluminum sheet with a thickness of 0.3-1.2 mm, and provide colored aluminum coil and aluminum sheet with various coating thicknesses such as single coating, double coating and back coating.
Thickness control of coloured aluminium sheet: Usually color coated aluminum coil can be divided into three components: substrate thickness, coating paint thickness, and protective film thickness. Generally, the thickness of the single-coated paint film is about 15um, and the thickness of the double-coated paint film is 25um. Nearby, the thickness of the paint film of the back coating is around 5-8um. The thickness of the protective film is usually 0.05 mm, and PE protective film is generally used. The medium-viscosity or high-viscosity protective film is more suitable as a paint protective film for color coated aluminum coil, which can avoid the process of pressing tile pressing and shearing. scratches, it is generally recommended that users apply film. It should be pointed out that the paint of fluorocarbon color-coated aluminum coil is double-coated, and the paint of polyester color coated aluminum sheet can be divided into single-coated and double-coated.
Thickness tolerance of coloured aluminium sheet: The thickness tolerance of color coated aluminum coils can generally be controlled around plus or minus 3-5 wires, which are products with relatively accurate tolerances. Haomei Aluminum provide a variety of high-precision color coated aluminum coils and coloured aluminium sheet, with guaranteed thickness and tolerances not exceeding the standard.
