European I-Beam (IPE) · EN 10365 · Europe
IPE A 400 is a European parallel-flange I-beam 397.0 mm deep with a 180.0 mm wide flange, weighing 57.4 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 400 the computed area agrees with the published value to 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 | 1,022,297 mm³ |
| Elastic modulus, Wel,y | 130,066 mm³ |
| Plastic modulus, Wpl,x | 1,143,901 mm³ |
| Plastic modulus, Wpl,y | 202,070 mm³ |
| Radius of gyration, rx | 166.6 mm |
| Radius of gyration, ry | 40.0 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
