1100 Color Coated Aluminum Sheet in customized colors, widths, coatings and surface finishes.
Why Choose 1100 Color Coated Aluminum Sheet?
1100 aluminum is a widely used pure aluminum grade for coated sheet and coil production. Its relatively low strength is balanced by excellent workability, making it suitable for products with bending, stamping, roll forming and decorative surface requirements.
- Excellent formability for bending, stamping, roll forming and deep drawing
- Good corrosion resistance for indoor and general environmental applications
- Reliable weldability for fabricated decorative and industrial components
- Smooth coated surface with uniform color and gloss
- Lightweight material that reduces transportation and installation costs
- Good thermal and electrical conductivity
- Available in coil, sheet, strip and cut-to-length panels
- Supports customized colors, dimensions and coating systems
If you need more strength than 1100 aluminum can provide, 3003 color coated aluminum coil is a practical alternative for applications where added strength and formability are important. For projects that still call for a commercially pure aluminum substrate, 1050 color coated aluminum sheet and coil is another option to consider.

PE, HDP and PVDF Coating Options for 1100 Aluminum
The right coating system depends on where the 1100 aluminum will be used, how the material will be formed and the level of outdoor durability required. Haomei Aluminum can supply 1100 color coated aluminum in different coating systems, allowing the same aluminum substrate to be matched to interior, general-purpose or demanding exterior applications.
PE Coating
PE coating is a practical choice for interior panels, ceilings, decorative components and other products where color, surface appearance and cost are key considerations. It is also widely used for general-purpose 1100 coated aluminum products that are not exposed to severe outdoor conditions.
- Broad range of standard and custom colors
- Well suited to interior decorative applications
- Good surface appearance for formed panels
- Cost-effective option for general-purpose products
HDP Coating
HDP coating is worth considering for 1100 aluminum products that will see more outdoor exposure than typical interior applications. Compared with standard polyester coating, HDP is generally selected when better resistance to weathering and longer-lasting surface appearance are needed.
- Better weathering performance than standard PE systems
- Suitable for selected exterior applications
- Available in a wide range of colors and finishes
- A practical choice for medium-duty outdoor exposure
PVDF Coating
PVDF coating is normally chosen for architectural and other demanding exterior applications where long-term color retention, weather resistance and appearance are important. For 1100 color coated aluminum used on building facades, wall systems and other exposed components, PVDF can provide a higher-performance coating solution.
- High resistance to outdoor weathering
- Good color and gloss retention over extended exposure
- Suitable for architectural exterior applications
- Custom colors available for project requirements

FAQ – 1100 Color Coated Aluminum Sheet
What is 1100 Color Coated Aluminum Sheet?
It is 1100 aluminum sheet coated with an organic coating system such as PE, HDP or PVDF. The coating provides the selected color and additional surface protection, while the 1100 aluminum substrate provides good formability and general corrosion resistance.
Why is 1100 aluminum suitable for color coating?
1100 is a commercially pure aluminum alloy with good ductility and workability. This makes it suitable for decorative panels, signage products and light-duty fabricated components where easy processing is important.
Can 1100 Color Coated Aluminum Sheet be bent?
Yes. 1100 aluminum is generally easy to bend and form. However, the required bend radius should be considered together with thickness, temper, coating system and forming equipment.
Which coating is better: PE or PVDF?
Neither coating is universally better. PE is commonly used for interior and general decorative applications, while PVDF is more appropriate for demanding architectural applications requiring higher weathering performance and long-term appearance.
Can Haomei provide custom colors?
Yes. Haomei can discuss standard colors, RAL-based colors and customized colors according to the application. For critical color-matching projects, an approved sample or reference should be confirmed before mass production.
Is 1100 better than 3003 for coated aluminum panels?
The answer depends on the product requirements. 1100 is attractive when easy forming and decorative appearance are priorities, while 3003 is often considered when higher mechanical strength is more important.
Can 1100 coated aluminum be supplied in coil form?
Yes. Depending on the manufacturing process, coated 1100 aluminum can be supplied in coil format for slitting, roll forming, panel production and other continuous fabrication processes.
What information should I include in an inquiry?
Please provide alloy and temper, thickness, width, sheet or coil format, coating type, color, quantity, application, packaging requirements and destination. This allows the manufacturer to prepare a more accurate quotation.
