American Standard Channel · AISC Shapes Database v15.0 · United States
C5X9 is an American Standard channel 127.0 mm deep with a 48.0 mm wide flange, weighing 13.4 kg/m. The dimensions below are the published AISC Shapes Database v15.0 values; the drawing is generated from them.
C-shapes are American Standard channels with tapered flanges — stringers, purlins and frames where a single flat back face is wanted.

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 C5X9 the computed area agrees with the published value to 0.01% and Ix to 0.08%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 58,318 mm³ |
| Elastic modulus, Sy | 7,490 mm³ |
| Plastic modulus, Zx | 72,008 mm³ |
| Plastic modulus, Zy | 15,135 mm³ |
| Radius of gyration, rx | 46.6 mm |
| Radius of gyration, ry | 12.5 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
