The C 100×50×20 is a developed-width profile: 216 mm of strip becomes the shape. That is why its weight per metre is calculated from the developed width and not from the outside dimensions. When you compare suppliers, compare developed width and wall, not the nominal height.
| Wall | kg/m | 6 m (kg) | 12 m (kg) |
|---|---|---|---|
| 2.0 mm | 3.39 | 20.3 | 40.7 |
| 2.5 mm | 4.24 | 25.4 | 50.9 |
Developed width 216 mm × wall × 7.85 g/cm³. Nominal.
