European H-Beam (HE M) · EN 10365 · Europe
HEM 300 is a European wide-flange H-section, heavy series 340.0 mm deep with a 310.0 mm wide flange, weighing 237.9 kg/m. The dimensions below are the published EN 10365 values; the drawing is generated from them.
HE M sections are the heavy H series, with thick flanges for high axial loads and stiff connections.

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 HEM 300 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 | 3,482,413 mm³ |
| Elastic modulus, Wel,y | 1,251,811 mm³ |
| Plastic modulus, Wpl,x | 4,077,674 mm³ |
| Plastic modulus, Wpl,y | 1,913,180 mm³ |
| Radius of gyration, rx | 139.8 mm |
| Radius of gyration, ry | 80.0 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
