European I-Beam (IPE) · EN 10365 · Europe
IPE 100 is a European parallel-flange I-beam 100.0 mm deep with a 55.0 mm wide flange, weighing 8.1 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 100 the computed area agrees with the published value to 0.03% and Ix to 0.01%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Wel,x | 34,202 mm³ |
| Elastic modulus, Wel,y | 5,789 mm³ |
| Plastic modulus, Wpl,x | 39,407 mm³ |
| Plastic modulus, Wpl,y | 9,146 mm³ |
| Radius of gyration, rx | 40.7 mm |
| Radius of gyration, ry | 12.4 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
