|---|---|
| Tolerance | ±0.10 mm general, ±0.05 mm on mating features |
| Finish | Zinc plated, powder coated, brushed, passivated |
About this part
What it is and why it is made that way
Reinforcing brackets are the part you add after the first article has shown where the frame is flexing. They are stamped with rolled edges and lightening cut-outs so they add stiffness at a fraction of the weight of a solid plate. Because they are produced on the same tool as the parts they reinforce, the fixing pattern lines up first time.
- Rolled edges to remove stress risers and sharp corners
- Lightening cut-outs sized to keep the section modulus high
- Stamped on the same tool as the associated frame parts
- Matched hole pattern to the base structure
Materials
- SPCC / SECC cold-rolled steel
- Stainless 304 / 201 sheet
- Galvanised steel
- Aluminium 5052 / 6061 sheet
Production processes
- Progressive stamping
- Single-bleed stamping
- Laser cutting
- CNC bending
- Welding and assembly
Typical applications
- Frame stiffening
- Cabinet reinforcement
- Guard frame support
- Vibration-damping stiffeners
Specification
Technical detail
The ranges below are what this shop typically holds. Anything tighter than the baseline is possible — send the drawing and we will confirm it against your specific tolerances rather than quote from a table.
| Material thickness | 0.5 – 6.0 mm, per drawing |
|---|---|
| Tolerance | ±0.10 mm general, ±0.05 mm on mating features |
| Finish | Zinc plated, powder coated, brushed, passivated |
| Secondary operations | Deburring, tapping, riveting, spot welding, assembly |
| Tooling | Customer-owned tooling accepted; new tooling quoted per project |
| Material thickness | 1.5 – 4.0 mm, per drawing |
| Edge condition | Rolled and deburred, no raw sheared edge in service |
| Weight saving | Typically 40 – 60% against a solid plate of equal stiffness |
Material and finish are yours to choose. The lists above are the families this part is normally made in. We will not substitute a grade or change a tolerance without telling you first — and asking.
