StructureCalcsHL 920 x 344
Extra-Wide-Flange Beam (HL) · EN 10365 · Europe
HL 920 x 344 is an extra-wide-flange beam 927.0 mm deep with a 418.0 mm wide flange, weighing 344.0 kg/m. The dimensions below are the published EN 10365 values; the drawing is generated from them.
HL sections are extra-wide light H-beams — long-span floor members whose wide flanges buy lateral stability.

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 HL 920 x 344 the computed area agrees with the published value to better than 0.01% and Ix to 0.62%. Where a value is also published, the published one above is the one to quote.
