# I and H beams (IPE, HEA, HEB)

Hot-rolled parallel-flange I and H beams: IPE 80 to IPE 600 (DIN 1025-5), HEA / IPBl 100 to 1000 (DIN 1025-3) and
HEB / IPB 100 to 1000 (DIN 1025-2), at any length.

## Geometry

Depth **h** along Y, flange width **b** along X, web thickness **tw**, flange thickness **tf**, root radius **r**
between web and flanges; square flange edges (the standards' small edge rounding is not modelled). The section is
centred on the origin and extruded along +Z by `length`. Section area and mass follow the tables.
