UPN 220 dimensions
| Dimension | Symbol | Value |
|---|---|---|
| Depth | h | 220 mm |
| Flange width | b | 80 mm |
| Web thickness | tw | 9 mm |
| Flange thickness | tf | 12.5 mm |

A delivered bar may differ from these nominal values within the rolling tolerances of EN 10279; invoicing goes by the mill certificate, not by the table. “—”: the sources give r for this size to different precision.
UPN 220 weight by length
| Length, m | Mass, kg |
|---|---|
| 1 | 29.4 |
| 2 | 58.8 |
| 3 | 88.2 |

Steel cost is mass times the price per kilogram: at a price C per kg a 12 m bar costs 352.8 × C and a 6 m bar 176.4 × C. Cutting, drilling and painting are priced separately; paint goes by surface area, not by weight.
UPN 220 section properties
| Property | Symbol | Value |
|---|---|---|
| Second moment of area, major axis | Iy | 2690 cm⁴ |
| Elastic section modulus, major axis | Wel,y | 245 cm³ |
| Radius of gyration, major axis | iy | 8.48 cm |
| Second moment of area, minor axis | Iz | 197 cm⁴ |
| Elastic section modulus, minor axis, at the flange tip | Wel,z | 33.6 cm³ |
Iy governs deflection, Wel,y bending stress, iy the slenderness of a strut. Iy / Iz = 13.7: in vertical bending the section is 13.7 times stiffer than sideways.

Frequently asked questions
How much does a 6 m and a 12 m UPN 220 weigh?
UPN 220 weighs 29.4 kg/m, so a 6 m bar is 176.4 kg and a 12 m bar 352.8 kg. Ten 12 m bars come to 3528 kg.
Which is heavier: IPE 220, HEA 220, HEB 220 or UPN 220?
Per metre: HEB 220 — 71.5 kg/m (h 220 mm); HEA 220 — 50.5 kg/m (h 210 mm); UPN 220 — 29.4 kg/m (h 220 mm); IPE 220 — 26.2 kg/m (h 220 mm). UPN is a channel and is not symmetric about its web — a different member for different jobs, compared here by weight only.
What does 220 mean in UPN 220?
The nominal depth in millimetres: UPN 220 is 220 mm deep with a 80 mm flange. The letters give the series: UPN, a channel with tapered flanges.
How many metres of UPN 220 are in a tonne?
34 m: 1000 kg / 29.4 kg/m. That is about 5.7 bars of 6 m or 2.8 bars of 12 m.
Does S235 or S355 steel change the weight of UPN 220?
No. The table mass is the cross-section area times the density of steel, 7850 kg/m³: 37.4 cm² × 0.785 = 29.36 kg/m. The grade to EN 10025-2 sets strength, not density. A real bar differs from nominal only within the rolling tolerances of EN 10279.
