What Does Custom Cutting Involve?
Ordering aluminium sheet to your dimensions means you receive exactly what you need — no extra waste or on-site trimming. At Metal Offcuts, we offer:
- Free trimming with precision guillotines for straight cuts
- Laser cutting for detailed shapes, curves, slots, and holes
- Size range from small panels to full sheets
If you only need straight cuts, we’ll trim it for free. For complex shapes, our CNC laser cutting produces accurate parts to your drawing.
Aluminium Sheet Thickness Guide – Uses & Applications
We stock a practical range of thicknesses suited to everything from craft and signage to heavier panels:
| Thickness | Common Uses |
|---|---|
| 0.5mm–1.2mm | Crafting, decorative panels, printing |
| 1.5mm–2.0mm | Signage, light fabrication, kitchen splashbacks |
| 3.0mm–4.0mm | Heavy-duty panels, fixtures, structural brackets |
Most flat sheets are Grade 1050A H14 for good formability and general use. For tougher applications, 5000-series aluminium may be available — for example our 5754 aluminium checker plate.
