Extra-Wide-Flange Beam (HL) · EN 10365 · Europe
HL 1100 x 548 is an extra-wide-flange beam 1,128.0 mm deep with a 407.0 mm wide flange, weighing 548.0 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 1100 x 548 the computed area agrees with the published value to better than 0.01% and Ix to 0.75%. Where a value is also published, the published one above is the one to quote.
| Property | Value |

| Elastic modulus, Wel,x | 25,634,029 mm³ |
| Elastic modulus, Wel,y | 2,770,665 mm³ |
| Plastic modulus, Wpl,x | 29,511,489 mm³ |
| Plastic modulus, Wpl,y | 4,349,125 mm³ |
| Radius of gyration, rx | 455.0 mm |
| Radius of gyration, ry | 89.9 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
