UPN 200 dimensions
| Dimension | Symbol | Value |
|---|---|---|
| Depth | h | 200 mm |
| Flange width | b | 75 mm |
| Web thickness | tw | 8.5 mm |
| Flange thickness | tf | 11.5 mm |
| Root radius | r | — |
| Cross-section area | A | 32.2 cm² |
| Mass per metre | G | 25.3 kg/m |
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 200 weight by length
| Length, m | Mass, kg |
|---|---|
| 1 | 25.3 |
| 2 | 50.6 |
| 3 | 75.9 |
| 4 | 101.2 |

Steel cost is mass times the price per kilogram: at a price C per kg a 12 m bar costs 303.6 × C and a 6 m bar 151.8 × C. Cutting, drilling and painting are priced separately; paint goes by surface area, not by weight.
UPN 200 section properties
| Property | Symbol | Value |
|---|---|---|
| Second moment of area, major axis | Iy | 1910 cm⁴ |
| Elastic section modulus, major axis | Wel,y | 191 cm³ |
| Radius of gyration, major axis | iy | 7.70 cm |
| Second moment of area, minor axis | Iz | 148 cm⁴ |
| Elastic section modulus, minor axis, at the flange tip | Wel,z | 27 cm³ |
Iy governs deflection, Wel,y bending stress, iy the slenderness of a strut. Iy / Iz = 12.9: in vertical bending the section is 12.9 times stiffer than sideways.

Frequently asked questions
How much does a 6 m and a 12 m UPN 200 weigh?
UPN 200 weighs 25.3 kg/m, so a 6 m bar is 151.8 kg and a 12 m bar 303.6 kg. Ten 12 m bars come to 3036 kg.
Which is heavier: IPE 200, HEA 200, HEB 200 or UPN 200?
Per metre: HEB 200 — 61.3 kg/m (h 200 mm); HEA 200 — 42.3 kg/m (h 190 mm); UPN 200 — 25.3 kg/m (h 200 mm); IPE 200 — 22.4 kg/m (h 200 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 200 mean in UPN 200?
The nominal depth in millimetres: UPN 200 is 200 mm deep with a 75 mm flange. The letters give the series: UPN, a channel with tapered flanges.
How many metres of UPN 200 are in a tonne?
39.5 m: 1000 kg / 25.3 kg/m. That is about 6.6 bars of 6 m or 3.3 bars of 12 m.
Does S235 or S355 steel change the weight of UPN 200?
No. The table mass is the cross-section area times the density of steel, 7850 kg/m³: 32.2 cm² × 0.785 = 25.28 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.
