Product Description
Product Description:PrePainted Aluminum Circle is a round aluminum material with a specific color or functional coating that has been pre-treated by roller coating, spraying and other processes, and is widely used in kitchenware, home appliances, industrial parts and other fields.
Lightweight: 2.7 g/cm³ density, suitable for high-frequency use scenarios.
Ready-to-use: Eliminate on-site painting steps, reducing production costs and time.
Environmental protection: no VOC emission, in line with EU REACH, US EPA standards.
Core Benefits:
Corrosion Resistance:
The PVDF coating has passed a 3000-hour salt spray test (ASTM B117) to adapt to coastal and industrial environments.
Food Safety:
The PE coating is FDA compliant and comes into direct contact with food (e.g. pizza trays, baking molds).
Thermal Properties:
The temperature resistance range is -40°C to 250°C (ceramic coating), suitable for high-temperature scenarios such as ovens and induction cookers.
Design Flexibility:
Support digital printing of customized patterns (such as brand logos, cultural totems) to enhance the added value of products.

Features
Pre-painted aluminium discs occupy a core position in European and American kitchenware, Asian electronics and global industrial fields with the advantages of light weight, food safety and thermal efficiency. For example, 3003 alloy PVDF-coated discs have become the standard equipment for outdoor cookware in North America, while the 1050 high thermal conductivity model has helped dissipate heat from 5G base stations in Japan. Its combination of customized design and environmental compliance is pushing traditional metal processing to be more efficient and greener, making it an innovative alternative to cast iron and stainless steel in many industries.
