|---|---|---|
| Mild / carbon steel | 7,850 | — |
| Stainless 304 / 316 | 8,000 | +2% |
| Aluminium | 2,712 | −65% |
| Copper | 8,940 | +14% |
| Brass | 8,530 | +9% |
| Cast iron | 7,200 | −8% |
| Galvanised iron (GI) | 7,870 | ≈ same |

The formula is the same for every metal: weight per metre (kg/m) = area (mm²) × density (kg/m³) ÷ 1,000,000. Only the density changes.
Cross-sectional area × length × density. Pick the material and profile above, enter the dimensions, and the calculator gives kg/m, per-piece and total weight instantly.
About 65% — the same section in aluminium weighs roughly one third of its steel weight, which is why it dominates weight-critical fabrication.
Slightly — 304/316 stainless is about 8,000 kg/m³ vs 7,850 for carbon steel, about 2% heavier.
