Color Coated Aluminum Plate Steel Sheet
Exceptional Mechanical Strength and Durability – Color-coated aluminum sheet retains the inherent high mechanical strength and toughness of aluminum, ensuring long-lasting performance and reliability in various structural and functional applications.
Superior Corrosion Resistance – The organic coating layer provides excellent protection against corrosion, effectively enhancing the lifespan of the material even in harsh environmental conditions, making it ideal for both indoor and outdoor use.
Attractive Appearance and Versatile Decorativeness – The pre-applied organic coating allows for vibrant colors and smooth finishes, offering strong aesthetic appeal for architectural, decorative, and design projects, while maintaining consistency and color stability over time.
Easy Processing and Wide Applicability – The sheet is highly formable and adaptable, suitable for punching, bending, deep drawing, and welding, allowing manufacturers to create practical, durable, and visually appealing products for a broad range of industrial, construction, and decorative applications.
Color-coated aluminum sheet is also called colored aluminum sheet, also called organic coating sheet or pre-coated aluminum sheet. Color-coated aluminum sheet is a composite material made by coating one or more layers of organic coating on the surface of an aluminum substrate after it passes through a color coating unit and then being baked and cured. Color-coated aluminum sheet has the advantages of both aluminum sheet and organic materials. It has the advantages of aluminum sheet such as high mechanical strength, good toughness, and easy processing and forming, and it also has the advantages of organic polymer coating materials such as good coloring, decorativeness, and corrosion resistance. It can be easily processed by punching, bending, deep drawing, welding, etc., and the products made are practical, suitable for decoration, easy to process, and durable.

Application of color aluminum plate
Color-coated aluminum plate has high decorative and corrosion resistance, so it is widely used in electronic appliances, food, construction, transportation and other fields, and the market demand is high. According to the different coatings used, color-coated aluminum can be divided into high-end fluorocarbon color coatings and relatively low-end polyester color coatings.
Aluminum plate oxidation coloring method
1. Chemical coloring: The oxidized aluminum material is immersed in an organic or inorganic dye solution, and the dye penetrates into the pores of the oxide film and is colored by chemical or physical action. The chemical coloring equipment is simple, the cost is low, and there are many kinds of colors, but the light resistance and corrosion resistance are poor, and it is only suitable for interior decoration.
2. Electrolytic coloring: The oxidized aluminum material is subjected to secondary electrolysis in a single metal salt or a variety of metal salt aqueous solutions. Under the action of an electric field, metal cations penetrate into the pores of the oxide film and deposit on the bottom of the pores. Make the oxide film produce bronze, brown, gray and red, cyan, blue and other tones.
3. Natural coloring: A method of coloring aluminum while anodizing. There are alloy coloring method and solution coloring method. The alloy color development method is to control the composition of the aluminum alloy to obtain different hues; the solution color development method, also known as the electrolytic color development method, is to control the composition of the electrolyte and the electrolysis conditions to control the hue. In actual production, organic acid is generally used as the electrolyte for natural coloring, and a small amount of sulfuric acid is added to adjust the pH.
4. For the oxidation and coloring of aluminum, an oxide film (Al2O3) is formed on the surface of aluminum and its alloy products by artificial methods, and different colors are applied to improve the wear resistance of aluminum materials, prolong the service life and increase the color and luster. The basic process of oxidation coloring is aluminum surface treatment, oxidation, coloring and subsequent hydration sealing, organic coating and other treatment processes.
