Standards & codes
Reference information
Commonly cited families (verify edition on your certificate):
- EN 10219
- EN 10210
- ASTM A500/A501
- GOST 8639
- GOST 8645
Hollow structural sections fall under EN 10219 (cold-formed), EN 10210 (hot-finished), ASTM A500/A501, and GOST 8639/8645 for square/rectangular tubes. Corner radii and corner reinforcement in rolled sections are not modeled in detail here.

Illustrative values for common sizes of Square tube at the density you selected. For procurement, always verify against mill certificates.
| OD (mm) | Wall (mm) | kg/m | |
|---|---|---|---|
| 40 | 3 | 3.485 | |
| 50 | 3 | 4.427 | |
| 60 | 3 | 5.369 | |
| 80 | 4 | 9.546 |
Figures follow the same geometric model as the calculator above; rounding and simplifications apply.
Method
How to calculate weight
Core model
V = (s² − (s − 2t)²) · L
m = ρ · VField names
Hollow square tubes use outer square minus inner square for area, then area × length × density—common for square hollow section weight and SHS kg/m lookups.
Wall thickness must stay consistent on all four sides for the model to stay accurate.
