European H-Beam (HE M) · EN 10365 · Europe
HEM 900 is a European wide-flange H-section, heavy series 910.0 mm deep with a 302.0 mm wide flange, weighing 332.5 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 900 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.
