American Standard Channel · AISC Shapes Database v15.0 · United States
C15X50 is an American Standard channel 381.0 mm deep with a 94.5 mm wide flange, weighing 74.4 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 C15X50 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, Sx | 882,716 mm³ |
| Elastic modulus, Sy | 62,972 mm³ |
| Plastic modulus, Zx | 1,123,934 mm³ |
| Plastic modulus, Zy | 134,308 mm³ |
| Radius of gyration, rx | 133.2 mm |
| Radius of gyration, ry | 22.2 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
