PE stone grain aluminium sheet
PE stone grain aluminium sheet description
PE stone grain aluminium sheet adopts the processing technology of spraying or roller coating, and the surface can also be sprayed with real stone paint, which is consistent with the real stone feel.
Common stone patterns are curtain walls PE stone grain aluminium sheet, gray PE stone grain aluminium sheet, 3d PE stone grain aluminium sheet, brick pattern color coated aluminum plates, real stone painted aluminum veneers, etc., special patterns can be customized. Some thinner aluminum plates can be reprocessed, such as 0.5mm, can be made into honeycomb aluminum plates, thermal insulation aluminum-plastic composite plates, etc.
PE stone grain aluminium sheet produced by STEK are strictly installed in accordance with the national standard inspection. The stone texture is really bright and the same as the stone. It can completely replace the real stone curtain wall panel.
PE stone grain aluminium sheet is the use of advanced spraying equipment, painting technology and digital color printing technology, through precise CNC positioning, patterns are formed during multiple painting and baking processes to overprint the stone grain on the surface of the aluminum sheet metal.
The coating of PE stone grain aluminium sheethas many excellent characteristics such as fingerprint resistant, high weather resistance, antibacterial, long life, antistatic, high durability, preservative, antistatic, high weather resistance etc .
The sample shall be carried out at the Hainan National Exposure Test Site or an area with equivalent climate environment according to GB/T 9276. The sample shall be placed at an angle of 45° to the south and the test time shall be 10 years.
Aluminum sheet pre-roll coating process
After special processing,PE stone grain aluminium sheet can resist large impact forces without being damaged. The thinnest stone is only 3-5mm thick and can be used in combination with aluminum plates, while ordinary granite stone plates are about 12mm thick, the overall weight of the stone is heavy and fragile. Therefore, transportation can save a lot of costs. If a large number of stone plates are used in engineering construction, it is the best choice.
Multi-layer painting process
Coating thickness: It can be divided into single coating (4μm-20 μm); double coating (25μm-28 μm); 3 coating (35μm-38μm).
PE stone grain aluminium sheet uses advanced spraying equipment, combining spraying technology with digital color printing technology. Through precise CNC positioning, patterns are formed during multiple painting and baking processes. This stone-imitation baking paint is overprinted on the metal surface of the aluminum plate.
PE stone grain aluminium sheet specifications
Aluminum base plate range:
Commonly used width: 1000mm, 1200mm, 1250mm, other special widths can be according to customer requirements; common alloys: 1100, 3003, 3004, 8011, 3105, 5052, other alloys can be according to customer requirements.
Advantages of PE stone grain aluminium sheet
The ink can be choosen are polyester, fluorocarbon system, which has high weather resistance.
Compared with stone, it is suitable for stamping and bending, and it can be processed into various shapes.
PE stone grain aluminium sheet The texture is clear and lifelike.
