Sheet metal: tolerances, sheet sizes and lead times
What we hold as standard on laser cutting, bending and tapping — and where engineering review begins.
- Sheet metal at FormHub holds ±0.1 mm on cut contours and ±0.2 mm on bend dimensions, with ±0.05 mm on specific features. We process sheet up to 3,000 × 1,500 mm and thicknesses from 0.5 to 25 mm; larger formats are quoted via engineering review.

Frequently asked questions
- How do tolerances stack across multiple bends?
- Each bend adds roughly ±0.2 mm. Across four consecutive bends the deviation on the final dimension can approach a millimetre. Always dimension from a single datum face rather than chain-dimensioning.
- What is the minimum distance from a hole to a bend line?
- Keep at least two material thicknesses plus the bend radius. Closer than that and the hole deforms into an oval during bending. Our DFM check flags this automatically.
- Which secondary operations run in the same order?
- Deburring, clinch nuts (PEM), tapping up to M12, TIG and MIG welding, powder coating in RAL colours and galvanising. One quote, one delivery, one point of contact for the finished part.
