Coated aluminum sheet is a premium aluminum product with a protective and decorative layer of paint or coating applied to its surface. Known for its excellent durability, corrosion resistance, and vibrant color options, coated aluminum sheets are widely used in various industries, including construction, transportation, appliance manufacturing and signage.
Manufactured through advanced coating technologies such as roller coating, coated aluminium sheets offer uniform color, strong adhesion, and long-lasting performance even in harsh environments. Available in a wide range of colors, finishes (matte, glossy, metallic), and thicknesses, coated aluminum sheets are ideal for applications like roofing, cladding, ceiling panels, and aluminum composite panels (ACP).

Color Description
Coated aluminum sheet can be processed into a variety of different colors and textures such as metallic color, wood grain color, marble color, etc. by special surface treatment technology to meet different architectural styles and decoration requirements.
Standard Color
The standard color of coated aluminum sheets is modulated according to the Ral color card. The basic colors are red, yellow, blue, green, white, gray and other colors and their derivative colors, which are suitable for most conventional applications.
Metallic Colors
The Metallic color of coated aluminum sheets simulate metal textures, such as silver gray, bronze, rose gold, etc., which add a sense of luxury and class to the product and are often used in high-end architectural decoration.
Printing Series
The printing series achieve natural texture effects such as wood grain and stone grain through special coating technology, providing more diversified choices for architectural design, esuitable for places that pursue natural and environmental protection concepts.

Process of Coating Aluminum
Advantages of Coated Aluminum Sheets:
There is no composite high temperature indentation on the surface of the coated aluminum sheet, no residual stress on the plate surface, and no deformation after shearing.
Coated aluminum sheets will not bend, deform, or expand in harsh environments under the influence of wind pressure, temperature, humidity, and other factors.
Coated aluminum sheets have strong coloring power and can be customized in color and pattern according to the building style. It can be coated with wood grain and marble grain to increase the beauty of the building.
Coated aluminum sheets have good durability and strong paint adhesion. Usually PE paint can be used for more than 15 years, and PVDF coating can be used for more than 30 years.
The coating of coated aluminum coils processed by roller coating and baking at high temperatures is less affected by the weather and environment, has high gloss retention, good color stability, and minimal color difference changes.
Coated aluminum coils have good acid and alkali resistance are not easy to corrode and produce toxic bacteria, and do not release any toxic gases, which has little impact on the environment. In addition, aluminum is 100% recyclable and has high recycling value.
Applications of Coated Aluminium Sheets:
Because of its good durability, light weight, mild and high quality, the coated aluminium sheets is suitable for large venues, airports, high-speed railway stations and other public buildings, as well as power plants, steel mills, chemicals, aquaculture and other industries with high requirements for anti-corrosion performance.
