Product Details
What is Coated Aluminum?
Coated aluminum refers to the process of applying a layer of colored coating onto the surface of aluminum sheet or coil.
HAOMEI Aluminum produces coated aluminum coils in various grades such as 1050, 1100, 3003, 3105, 5052, 5754, and 8011.
All color-coated aluminum coils are ISO9001 certified and available in all RAL colors. Surface finishes include polyester (PE), PVDF, and PE coatings, with customizable thickness, width, and length according to customer requirements.
These products are widely used in aluminum façade panels, honeycomb panels, aluminum ceilings, roofing systems, and tank manufacturing.
About Polyester Coated Aluminum Coil
PE coated aluminum coil, also known as polyester coated aluminum coil, is made by coating the surface of an aluminum alloy substrate with multiple layers of polyester organic paint, followed by high-temperature baking and curing to form a composite material.
About the Polyester (PE) Coating
This UV-resistant coating uses high-molecular polymers as monomers and adds alkyd resin. It is available in matte or glossy finishes to suit your needs. The tight molecular structure gives the coating a smooth, glossy surface, ensuring excellent printability. This coating is specifically designed for interior aluminum decorative and signage substrates and comes with a 7-year warranty.

Advantages of PE Coated Aluminum Coil
Weather and Corrosion Resistance
Polyester coatings have excellent resistance to UV rays, acid rain, and corrosion. They can be used outdoors for long periods without fading or chalking, ensuring lasting beauty and durability for buildings or decorative applications.Lightweight and Easy to Install
Aluminum has a low density-only one-third that of steel-—making construction lighter and faster while reducing the load on building structures.Economical and Practical
Due to its low density and ease of installation, aluminum provides an economical and efficient solution for various architectural and industrial applications.Rich Color Options
The pigment system of PE coatings is mature and stable, offering strong color expression. A wide range of gloss levels and saturation can be easily achieved to meet designers' diverse aesthetic needs.Excellent Workability
PE coated aluminum can be deeply drawn, bent, stretched, rolled, folded, and cut, making it suitable for different industrial and architectural processing requirements.Environmentally Friendly and Recyclable
Aluminum is a fully recyclable material, aligning with modern environmental protection and sustainability trends.
