How much do the lengths weigh?
| 6 m lengths | 1 | 5 | 10 | 25 | 50 | 100 |
|---|---|---|---|---|---|---|
| Weight | 11.88 kg | 59.4 kg | 118.8 kg | 297 kg | 594 kg | 1,188 kg |
| Metres | 6 m | 30 m | 60 m | 150 m | 300 m | 600 m |
How much load does the 76 × 51 × 6 unequal 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 |
|---|---|---|---|---|
| Upright (76 mm high) | 890 kg* | 445 kg* | 295 kg* | 180 kg |
| Flat (51 mm high) | 435 kg* | 215 kg* | 120 kg | 66 kg |
Moment of inertia 42.8 cm⁴ upright · 15.72 cm⁴ flat; section modulus 8.39 cm³ upright · 4.08 cm³ flat. * 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.

Data from the Perfiles de Aluminio standard profile catalogue, 2026 edition, published with its permission. The weight per metre is the one declared by the manufacturer; the actual weight may vary within the tolerances of the standard. The equivalent cross-section is calculated with a density of 2.699 g/cm³. Standard length: 6 m.
