The pre painted aluminum sheet is aluminum sheet whose surface has been coated and colored. Because it has good flatness, corrosion resistance, decoration and mechanical properties, it is favored by the market and is widely used in architectural decoration, food packaging, electronic appliances, printing, transportation and other fields.
1. Painted aluminum sheet 5x10: It refers to 5’ and 10’ respectively, that is 5 foot and 10 foot. Its size in the unit of mm is 1524mm x 3048mm.
2. Colored aluminum sheet 4x8: It represents 4 foot and 8 foot, that is 1219 mm x 2438 mm.
3. Coated aluminum 4x10: Its another popular name is aluminum sheet 48” x120”. Its size is 1219 mm x 3048 mm.
Aluminum size | Equivalent name | Foot | Millimeter |

5x12 aluminum sheet | 5’ x12’ aluminum sheet | 5ft x 12 ft | 1524 mm x3658 mm |
The thickness of the pre painted aluminum sheet is mainly related to the coating equipment. The usual coating equipment can process the color coated aluminum sheet with a thickness of 0.3-1.2 mm. The coated aluminum plate with such thickness range can satisfy most uses.
The painted aluminum sheet thickness can be divided into three parts: substrate thickness, coating paint thickness, and protective film thickness. Generally, the thickness of the single-coated paint film is around 15um, the thickness of the double-coated paint film is around 25um and 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.
Medium-viscosity or high-viscosity protective film is more suitable for the protective film of the color coated aluminum sheet which can avoid scratches in the process of pressing, bending or shearing.
The pre painted aluminum sheet for roof is coated with a layer of fluorocarbon paint or polyester paint, which makes the aluminum plate have excellent characteristics such as UV resistance, acid and alkali resistance, and high weather resistance. The common alloys are 1100, 3003, 3004, 8011, 3105, 5052, etc. The thickness range is 0.18-2.5 mm. The common width 1000 mm, 1200mm and 1250 mm.
What are the advantages of the painted aluminum sheet? Compared with the ordinary aluminum sheet, it has the following features:
1. The texture is clear and beautiful, with a sense of fashion and technology.
2. It has excellent weather resistance, no deformation and long-lasting bright color.
3. It is of strong decoration, convenient installation and wide application.
