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.
UPN 260 weight by length
| Length, m | Mass, kg |

Steel cost is mass times the price per kilogram: at a price C per kg a 12 m bar costs 454.8 × C and a 6 m bar 227.4 × C. Cutting, drilling and painting are priced separately; paint goes by surface area, not by weight.
UPN 260 section properties
| Property | Symbol | Value |
|---|---|---|
| Second moment of area, major axis | Iy | 4820 cm⁴ |
| Elastic section modulus, major axis | Wel,y | 371 cm³ |
| Radius of gyration, major axis | iy | 9.99 cm |
| Second moment of area, minor axis | Iz | 317 cm⁴ |
| Elastic section modulus, minor axis, at the flange tip | Wel,z | 47.7 cm³ |
Iy governs deflection, Wel,y bending stress, iy the slenderness of a strut. Iy / Iz = 15.2: in vertical bending the section is 15.2 times stiffer than sideways.

Frequently asked questions
How much does a 6 m and a 12 m UPN 260 weigh?
UPN 260 weighs 37.9 kg/m, so a 6 m bar is 227.4 kg and a 12 m bar 454.8 kg. Ten 12 m bars come to 4548 kg.
Which is heavier: HEA 260, HEB 260 or UPN 260?
Per metre: HEB 260 — 93 kg/m (h 260 mm); HEA 260 — 68.2 kg/m (h 250 mm); UPN 260 — 37.9 kg/m (h 260 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 260 mean in UPN 260?
The nominal depth in millimetres: UPN 260 is 260 mm deep with a 90 mm flange. The letters give the series: UPN, a channel with tapered flanges.
How many metres of UPN 260 are in a tonne?
26.4 m: 1000 kg / 37.9 kg/m. That is about 4.4 bars of 6 m or 2.2 bars of 12 m.
Does S235 or S355 steel change the weight of UPN 260?
No. The table mass is the cross-section area times the density of steel, 7850 kg/m³: 48.3 cm² × 0.785 = 37.92 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.
