American Standard Beam · AISC Shapes Database v15.0 · United States
S24X80 is an American Standard beam 609.6 mm deep with a 177.8 mm wide flange, weighing 119.1 kg/m. The dimensions below are the published AISC Shapes Database v15.0 values; the drawing is generated from them.
S-shapes are American Standard beams with narrow, tapered flanges — the oldest rolled I-profile in the catalogue, still used for crane rails and work on older structures.

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 S24X80 the computed area agrees with the published value to better than 0.01% and Ix to 0.37%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 2,878,430 mm³ |
| Elastic modulus, Sy | 200,600 mm³ |
| Plastic modulus, Zx | 3,354,083 mm³ |
| Plastic modulus, Zy | 341,960 mm³ |
| Radius of gyration, rx | 240.6 mm |
| Radius of gyration, ry | 34.3 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
