Aluminium coil roll for 3D letter is high-quality, durable, and lightweight materials used in signage, advertising, and decorative projects. These coils are perfect for making channel letters, 3D signs, and custom designs. Available in various alloys and thicknesses, aluminium coil rolls offer corrosion resistance and easy fabrication.
Specifications
| Feature | Common Specifications (Units) | Digitalized Types / Examples |
|---|---|---|
| Alloy | 3003, 5052 (most common for channel letters) | 3003-H14, 5052-H32 |
| Temper | H14, H16 (for formability and strength) | H14, H16 |
| Width | 50 mm – 150 mm (2 in – 6 in) | 50, 60, 75, 100, 120, 150 mm |
| Thickness | 0.4 mm – 1.0 mm (0.016 in – 0.040 in) | 0.4, 0.5, 0.6, 0.8, 1.0 mm |
| Finish | Pre-painted (White, Black, Red, Blue, etc.), Mill, Anodized | Pre-painted_White, Gloss_Black, Anodized_Silver |
| Coil Length | Up to 1000 meters (approx. 3300 feet) | 500m, 1000m |
Explanation of Types:
- Alloy: 3003 alloy offers excellent formability and corrosion resistance, while 5052 provides higher strength, especially important for larger or wind-exposed letters.
- Temper: H14 and H16 tempers are ideal as they allow the aluminium strip to be bent easily without cracking, yet retain sufficient hardness for a sturdy 3D letter structure.
- Width: The width of the aluminium coil roll directly determines the depth (or return height) of the 3D letter. Common depths for channel letter vary based on letter size and design.
- Thickness: Thicker material provides greater rigidity but can be harder to bend for tight curves.
- Finish: Pre-painted coils save time and ensure a consistent, durable color finish directly from the supplier. Mill finish is used if custom painting is done after fabrication.
Sizes and Digital Specifications
| Coil Width | Thickness | Weight per Coil | Best For |
|---|---|---|---|
| 100mm – 500mm | 0.3mm – 1.0mm | 500kg | Small 3D letters, indoor signs |
| 500mm – 1000mm | 0.5mm – 1.5mm | 1000kg | Medium signage, channel letters |
| 1000mm – 1250mm | 1.0mm – 2.0mm | 2000kg – 3000kg | Large 3D letters, architectural panels |
Applications
Aluminium coil rolls for 3D letters are widely used in:
- Signage and Advertising: Channel letters, logo signs, shop fronts.
- Interior Decoration: Wall art, decorative panels.

- Industrial Use: Lightweight components in machinery and vehicles.
What is an Aluminium Coil Roll 3D Letter?
An aluminium coil roll 3D letter refers to a type of signage component where flexible aluminium coil stock. Imagine a flat letter shape – the “face” – and then imagine building up the edges to give it depth.
These 3D letters, also known as channel letters, are a staple for modern outdoor signs and commercial signs. The use of aluminium coil roll ensures a seamless, strong, and visually appealing finish that stands the test of time.
Why Choose Aluminium Coil Roll for 3D Letters?
The choice of aluminium coil roll for fabricating 3D letters is no accident. Aluminum offers a unique combination of properties that are perfect for signage fabrication:
- Lightweight: Aluminium is significantly lighter than steel, making metal letters easier and safer to install, especially on large facades. This also reduces structural stress on buildings.
- Durable: Despite being lightweight, aluminum is incredibly strong and resistant to impacts, ensuring your custom signs maintain their integrity.
- Corrosion-Resistant: Unlike steel, aluminum naturally forms a protective oxide layer that prevents rust and corrosion, even in harsh weather conditions. This is crucial for outdoor signs.
- Formability: easily bent, routed, and welded by specialized machinery, allowing for complex and precise letter shapes.
- Aesthetic Versatility: painted, anodized, or polished to achieve virtually any desired look, matching brand guidelines perfectly.
- Cost-Effective: While offering premium quality, aluminium coil stock provides an efficient and economical material solution for producing high-quality channel letters.
