An Aluminum H Channel is an extruded profile with a cross-section shaped like the letter “H.” It consists of two parallel flanges connected by a central web, creating two channels for holding or joining panels, boards, or sheets.
Lightweight, corrosion-resistant, and easy to fabricate, aluminum H channels are widely used in Canadian construction, signage, furniture, and glazing industries.
Common Uses
- Construction & Architecture – Joining polycarbonate sheets, aluminum composite panels (ACP), or glass panels in walls, facades, or partitions.
- Signage & Display – Creating neat, aligned joints between sign boards or acrylic displays.
- Furniture & Interiors – Framing glass or acrylic inserts in cabinets, partitions, or decorative panels.
- Outdoor Structures – Greenhouses, pergolas, patio covers where weather resistance is key.
- Marine & Industrial – Saltwater-resistant framing in docks, boats, and industrial partitions.
Key Advantages
- Corrosion-resistant – Ideal for Canada’s varying climates, including coastal and snowy regions.
- Lightweight but strong – Easy to handle, yet structurally stable.
- Customizable – Available in anodized, powder-coated, or mill finishes.
- Easy to install – Can be cut with basic tools and fitted quickly.
Standard Sizes
H channels are sized based on the thickness of the panel they are meant to hold.
| Panel Thickness | Inside Width (mm) | Inside Width (in) | Web Thickness (mm) | Web Thickness (in) | Common Lengths (m) | Common Lengths (ft) |
|---|---|---|---|---|---|---|
| 4 mm | 4.2 mm | 0.165″ | 1.0 mm | 0.039″ | 3, 6 | 10, 20 |
| 6 mm | 6.2 mm | 0.244″ | 1.2 mm | 0.047″ | 3, 6 | 10, 20 |
| 8 mm | 8.2 mm | 0.323″ | 1.4 mm | 0.055″ | 3, 6 | 10, 20 |
| 10 mm | 10.2 mm | 0.402″ | 1.6 mm | 0.063″ | 3, 6 | 10, 20 |
| 12 mm | 12.2 mm | 0.480″ | 1.8 mm | 0.071″ | 3, 6 | 10, 20 |
Note: Custom sizes are available for thicker panels or unique applications.
