European H-Beam (HE B) · EN 10365 · Europe
HEB 320 is a European wide-flange H-section 320.0 mm deep with a 300.0 mm wide flange, weighing 126.7 kg/m. The dimensions below are the published EN 10365 values; the drawing is generated from them.
HE B sections are the standard-weight European H — the default Eurocode column section.

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 HEB 320 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 | 1,926,471 mm³ |
| Elastic modulus, Wel,y | 615,922 mm³ |
| Plastic modulus, Wpl,x | 2,149,240 mm³ |
| Plastic modulus, Wpl,y | 939,097 mm³ |
| Radius of gyration, rx | 138.2 mm |
| Radius of gyration, ry | 75.7 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
