PE coated aluminum, also known as polyester coated aluminum, is aluminum sheet or coil with a polyester (PE) coating applied to its surface through a roller coating or spray coating process. PE coating is the most widely used coating type for aluminum due to its excellent color variety, good flexibility, and cost-effectiveness. Together with PVDF coated aluminum, they are the two most common color coated aluminum products on the market. PE coated aluminum is widely used in aluminum ceilings, aluminum composite panels, building facades, roofing, signage, electronics, and more.

What Is PE Coating?
PE coating stands for polyester coating. It is a thermosetting coating system based on polyester resin, cured at high temperature to form a durable, decorative film on the aluminum surface. Polyester coatings offer a rich selection of colors, good surface smoothness, and reliable flexibility, making them one of the most popular and cost-effective choices for coated aluminum products.
Compared to PVDF (fluorocarbon) coatings, PE coatings are more affordable and provide sufficient performance for interior applications and moderate outdoor environments. For a detailed comparison of PVDF, PE, and HDPE coatings, see our guide: PVDF vs PE vs HDPE Coating.
Advantages of PE Coated Aluminum
- Rich color options: Available in solid colors, metallic finishes, wood grain, stone grain, brushed, and mirror effects to meet diverse design requirements.
- Realistic patterns: Wood grain and stone grain finishes provide lifelike texture and a natural aesthetic appearance.
- Lightweight: Aluminum has low density, making PE coated aluminum panels easy to transport, handle, and install.
- Good weather resistance: The polyester coating is formed by high-temperature baking, providing stable color, lasting gloss, and minimal color difference with a warranty of up to 10 years.
- Environmental resistance: Resistant to salt, alkali, mild acid rain, and rust. The coating is also flame-retardant.
- Excellent formability: PE coated aluminum has the bending and folding strength required for decorative panels and remains stable through seasonal temperature changes without cracking, deformation, or expansion.
- Easy maintenance: The smooth coating surface is easy to clean — simply wipe with a damp cloth.
- High cost performance: Polyester coating is significantly more affordable than PVDF fluorocarbon coating, offering excellent value for budget-conscious projects.
PE Coated Aluminum Production Process
Our PE coated aluminum is manufactured using advanced roller coating and spraying production lines. The process includes surface pretreatment, primer application (where applicable), top coat application, and high-temperature curing to ensure strong adhesion, uniform color, and consistent quality.
