European Standard I-Beam (IPN) · EN 10365 · Europe
IPN 240 is a European taper-flange I-beam 240.0 mm deep with a 106.0 mm wide flange, weighing 36.2 kg/m. The dimensions below are the published EN 10365 values; the drawing is generated from them.
IPN beams are the classic European taper-flange I — a legacy series still rolled, with the 14% flange taper reproduced in the drawing.

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 IPN 240 the computed area agrees with the published value to 1.24% and Ix to 1.34%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
