Holes that need re-drilling at assembly
When brackets come from rotating shops, each batch resets the tooling β hole positions drift and your fitters compensate on the line.
Solution Β· Sheet Metal Fabrication
A bracket is a simple part until hole patterns drift a millimeter between batches and your assembly line starts re-drilling. Our bracket workflow locks punch tooling, bend sequences and hole positions per project β verified on first articles before any batch ships.

Forming accuracy
Press-brake bending with planned bend sequences and springback compensation.
Hole position control
Punch tooling and laser cutting hold hole patterns; positions verified on first articles.
Finish scope
Coating and surface expectations written into the inspection plan and quotation.
When brackets come from rotating shops, each batch resets the tooling β hole positions drift and your fitters compensate on the line.
Unplanned springback turns a 90Β° drawing into a batch of 88Β° brackets, and flat mating surfaces become shimming work.
Mild steel specified for a coastal or outdoor installation fails in the field β the cost lands on your warranty, not the supplier's.
Every bracket project starts with a drawing review where material, hole pattern, bend radii and finish scope are written into the inspection plan. Punch tooling and stored bend sequences hold geometry across batches, and first articles verify positions and angles before release.
TRUMPF TruMatic 6000 and Amada punching cut blanks and hole patterns from your drawings.
Press-brake bending with stored sequences and springback compensation keeps angles consistent.
Punch tooling per project holds hole positions across repeat batches without re-drilling.
Multi-part brackets and stiffeners welded by robot or hand, checked on first articles.
Select the material family and thickness range to see general bend-radius guidance used in bracket design. Final radii, springback compensation and tooling are confirmed at drawing review.
For 2β3 mm mild steel, plan for an inside bend radius around 1Γ thickness and a slight overbend to compensate springback.
Bend-radius guidance is a general engineering reference, not a bending guarantee. Final radii, springback compensation and tooling are confirmed at drawing review.

βHole patterns from the last four batches bolted straight on β our fitters noticed before we did.β
βMaterial certificates arrive with the shipment, which our site teams stopped questioning.β
βOne inspection plan covers brackets and machined parts now, so freight and paperwork got simpler.β
