European Parallel-Flange Channel (UPE) · EN 10365 · Europe
UPE 400 is a European parallel-flange channel 400.0 mm deep with a 115.0 mm wide flange, weighing 72.2 kg/m. The dimensions below are the published EN 10365 values; the drawing is generated from them.
UPE channels are the parallel-flange successors to UPN — easier to bolt through and slightly lighter at the same depth.

Derived section properties
Integrated from the section's own outline including the root and toe radii, whose arcs are integrated analytically rather than approximated by facets. For UPE 400 the computed area agrees with the published value to 0.03% and Ix to better than 0.01%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Wel,x | 1,049,034 mm³ |
| Elastic modulus, Wel,y | 122,573 mm³ |
| Plastic modulus, Wpl,x | 1,262,664 mm³ |
| Plastic modulus, Wpl,y | 220,836 mm³ |
| Radius of gyration, rx | 151.1 mm |
| Radius of gyration, ry | 33.7 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
