Color Coated Aluminum Circle Disc
What is a Color Coated Aluminum Circle?
A color coated aluminum circle is made from high-quality aluminum or aluminum alloy coils/sheets as the base material. After surface pre-treatment, multiple layers of organic color coatings (such as Polyester PE, Fluorocarbon PVDF, etc.) are applied on the surface and cured through a baking process to produce pre-painted circular aluminum blanks.
Color-coated aluminum discs combine the advantages of aluminum's lightweight and excellent formability with the decorative, weather-resistant, and protective properties provided by the coating. The coating is applied before forming, effectively improving production efficiency and ensuring consistent product quality.
Color coated aluminum circles are widely used in cookware manufacturing, lighting fixtures, signage, and decorative applications where both appearance and durability are highly required.
The color-coated aluminum circle disc is protected from environmental factors such as moisture and chemicals, extending its lifespan. The color coating offers a variety of colors and finishes. Color-coated aluminum discs are versatile materials used across various industries, offering both functional and decorative advantages. They combine durability, aesthetic appeal, and protective performance, making them suitable for a wide range of applications.

Color Options for Color Coated Aluminum Circle Disc
Color-coated aluminum discs come in a wide range of colors, including red, yellow, green, black, blue, and more. The colored coating on these discs makes them visually appealing and versatile, meeting various aesthetic and decorative needs. They are widely used in various products, particularly in kitchenware.
Color Coated Aluminum Circle Disc Coating Types
Color Coated Aluminum Circle Disc can adopt various surface coating systems depending on different application scenarios, usage environments, and processing requirements. They are widely used in cookware manufacturing, decorative products, and architectural aluminum products. The common coating types and their characteristics are as follows:
PE (Polyester) Coating
PE (Polyester) coating is one of the most widely used types for color coated aluminum circle discs, mainly suitable for indoor use, such as the exterior surface of cookware, kitchenware, and decorative aluminum products.
This coating features good adhesion, formability, and color retention. Under normal usage conditions, its service life can reach 10–15 years, making it a cost-effective coating solution that balances performance and price.
PVDF (Fluorocarbon) Coating
PVDF (Polyvinylidene Fluoride) fluorocarbon coating belongs to the high-end color coating system, known for its excellent weather resistance, UV resistance, and long-term color stability.
This coating is commonly used for outdoor aluminum products, architectural aluminum materials, and high-end cookware aluminum discs that require superior appearance and durability. It is especially suitable for applications exposed to sunlight and complex weather conditions over long periods.
Food-grade / Non-stick Coating (PTFE)
Food-grade coatings are mainly used for cookware-grade aluminum discs. Among them, PTFE (Teflon) non-stick coating is specifically designed for the interior of cookware, significantly reducing food adhesion and improving cooking efficiency and ease of cleaning.
Some food-grade coatings can also be applied to aluminum discs for pot bottoms or lids, with specific configurations customized according to customer product standards and market demands.
Coating Process Description
Color Coated Aluminum Circle Discs usually adopt the roll coating (Roll Coating) process, with the coating applied at the aluminum coil (Color Coated Aluminum Coil) stage, and then the discs are stamped from the coated coil.
This production method ensures uniform coating thickness, stable surface quality, and effectively enhances the consistency and yield of color coated aluminum discs during stamping, drawing, and deep processing.
Coating Type Comparison
| Coating | Warranty Period | Coating Thickness | Applicable Scenarios |
| Polyester PE | 10 years | Single layer 4-20μm, Double layer 25-28μm | Indoor decoration, cookware, small appliances |
| Fluorocarbon PVDF | Longer than PE | Double layer 25-28μm, Triple layer 35-38μm | Outdoor architecture, curtain walls, high-end decoration |
| Epoxy | 5-8 years | 15-25μm | Industrial anti-corrosion, special functional components |
| Anodized | Long-term | 5-20μm | Wear-resistant, electrically and thermally conductive components |

Manufacturing Process of Color Coated Aluminum Circle Disc
First, the appropriate aluminum material is selected according to the intended application: 1060 is commonly used for cookware, while 3003 is more often used for architectural decoration. After selecting the material, the aluminum coil undergoes hot rolling or cold rolling to achieve the desired thickness. To improve formability, the aluminum is annealed, enhancing its ductility and flexibility.
Next comes surface treatment. The aluminum coil is first thoroughly cleaned and then chromated to ensure that subsequent coatings adhere firmly and are more durable. The coating process can be carried out by roll coating or spraying, with PE, PVDF, and other coatings applied in multiple layers to increase service life. After coating, the material is baked at high temperatures to fully cure the coating, ensuring it does not easily peel or flake.
Finally, the aluminum coil enters the stamping stage, where it is cut into circular shapes using molds, and the edges are chamfered or polished. Each finished disc undergoes strict quality inspection to verify dimensions and coating integrity, and is then carefully packaged to ensure it reaches the customer in perfect condition.
