European I-Beam (IPE) · EN 10365 · Europe
IPE O 550 is a European parallel-flange I-beam 556.0 mm deep with a 212.0 mm wide flange, weighing 123.0 kg/m. The dimensions below are the published EN 10365 values; the drawing is generated from them.
IPE sections are the European parallel-flange I-beam series — the standard flexural member of Eurocode practice.

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 IPE O 550 the computed area agrees with the published value to better than 0.01% 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 | 2,847,387 mm³ |
| Elastic modulus, Wel,y | 304,187 mm³ |
| Plastic modulus, Wpl,x | 3,263,379 mm³ |
| Plastic modulus, Wpl,y | 480,515 mm³ |
| Radius of gyration, rx | 225.2 mm |
| Radius of gyration, ry | 45.5 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
