We Cut It Your Way
We know that no two jobs are the same. That’s why we don’t just sell standard lengths — we cut and finish every steel channel to suit your specs. Send through your measurements and we’ll make it happen.
You can choose from:
- Custom lengths
- Specific thickness or flange sizes
- Hole punching or notching
Our default finish is Zinc Phosphate Primer, but if you need something stronger or better suited to the elements, we also offer:
- Hot dip galvanised
- Powder coated
- Hot zinc spray
You won’t need to chase updates either — we keep things clear from start to finish.
What Is a Steel Channel?
Think of a steel channel as a support beam shaped like a C, U, J or Z. They’re rolled from mild steel and used to add strength and structure to frames, walls, and roofs, without adding unnecessary weight.
Here’s a quick rundown:
- C-channel / Parallel flange channel: Tapered flanges. Great for longer spans and general framing.
- U-channel: Flat flanges. Often used in window and door framing.
- J-channel: One long side, one short. Ideal for neat trims around panels or louvres.
- Z-channel: Shaped to connect materials at angles. Common in metal roofing or siding.
