- How it is measured
- A is the length of the legs, which are equal; B is the thickness. CR: rounded edge. It is a different profile, not the same size.
How much do the lengths weigh?
| 6 m lengths | 1 | 5 | 10 | 25 | 50 | 100 |
|---|---|---|---|---|---|---|
| Weight | 4.79 kg | 23.97 kg | 47.94 kg | 119.9 kg | 239.7 kg | 479.4 kg |
| Metres | 6 m | 30 m | 60 m | 150 m | 300 m | 600 m |
How much load does the 50.8 × 50.8 × 3 equal angle take?
Supported at both ends, with the load at midspan: how many kilos it takes before it bends more than 1/200 of the span (what windows and light structures usually accept) or goes past the elastic limit of 6063-T5 aluminium.
| Span | 0.5 m | 1 m | 1.5 m | 2 m |
|---|---|---|---|---|
| Load at midspan | 215 kg* | 110 kg* | 56 kg | 32 kg |
Moment of inertia 7.51 cm⁴; section modulus 2.03 cm³. * Here the strength of the material governs, not the deflection. A guidance calculation for a straight beam with sharp corners, E = 69 GPa, without its own weight or buckling of thin walls: for a structure, the check must be done by an engineer.
