European I-Beam (IPE) · EN 10365 · Europe
IPE A 120 is a European parallel-flange I-beam 117.6 mm deep with a 64.0 mm wide flange, weighing 8.7 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 A 120 the computed area agrees with the published value to 0.05% and Ix to 0.22%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Wel,x | 43,610 mm³ |
| Elastic modulus, Wel,y | 6,994 mm³ |
| Plastic modulus, Wpl,x | 49,690 mm³ |
| Plastic modulus, Wpl,y | 10,963 mm³ |
| Radius of gyration, rx | 48.3 mm |
| Radius of gyration, ry | 14.3 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
