Sheet metal
Metal sheet is cut, then bent into brackets, panels, covers and boxes.
What it is
Sheet metal parts start as a flat sheet that is laser cut and then bent on a press brake into its final 3D shape. It is a cost-effective way to make strong, light parts such as brackets, enclosures, covers and chassis.
Compared with CNC machining, sheet metal parts are usually cheaper for larger, thin-walled shapes. Compared with laser cutting, they add bends.
Good for
- Brackets and angle mounts
- Enclosures, boxes and covers for electronics
- Panels and chassis
- Guards and shields
- Simple frames and supports
Materials
These are the materials you can choose in the price calculator. If you are not sure, keep the first option — it suits most parts. See all materials for more detail.
- Steel (mild steel) — strong and low cost
- Stainless steel (304) — does not rust
- Aluminium (5251) — light, does not rust
- Copper — conducts electricity and heat
Surface finishes
A finish changes how the part looks and feels, and can protect it. It does not change the shape.
- As made — bare metal
- Deburred — sharp edges smoothed
- Zinc plated — rust protection for steel
- Powder coated — a tough painted colour finish
Which file to send
A 3D model (STEP or IGES) of the finished, bent part is best. Use the same wall thickness everywhere, as the part is made from one sheet. If you have a flat pattern (DXF), you can send it too.
Tips for a good result and a lower price
- Use one sheet thickness for the whole part.
- Keep holes a little away from bend lines so they do not stretch.
- Inside bend corners are rounded; a radius equal to the sheet thickness is a good default.
- Very small flanges are difficult to bend — keep each flange at least about 4 × the sheet thickness.
Common questions
What is the difference between laser cutting and sheet metal?
Laser cutting makes flat parts. Sheet metal adds bending, so you get a 3D shape such as a bracket or a box.
Can you add threads or nuts?
Ask us in the order notes. Our engineer will confirm what is possible for your part.
Can parts be painted?
Yes — choose the powder-coated finish and tell us the colour you want in the order notes.
