Applications
Where angles are used
Extruded angles have a filleted inside corner that strengthens the root compared with bent sheet. Other sizes on request.
- Brackets and supports
- Edge trims and protection
- Reinforcement
- Framing
Questions
How do you calculate aluminum angle weight?
For an equal angle, area ≈ t × (2A − t) in mm², plus a small amount for the root fillet; multiply by 0.0027 for kg per metre.
