Square Tube Weight Calculator
Weight = (A² − (A−2t)²) × L × density.
Steel SHS Weight (kg/m, side × wall)
| A × t | kg/m |
|---|
| 40 × 3 | 3.41 |
| 50 × 4 | 5.64 |
| 80 × 5 | 11.5 |
| 100 × 6 | 17.6 |
| 150 × 8 | 34.8 |
Formula
Weight (kg/m) = (A² − (A−2t)²) × ρ × 10⁻⁶ (mm)
Worked Example
100 × 100 × 6 SHS: (100² − 88²) × 7850 × 10⁻⁶ = 17.6 kg/m.
FAQ
How is square tube weight calculated?
Outer area minus inner area, times length times density.
