American Standard Channel · AISC Shapes Database v15.0 · United States
C4X7.25 is an American Standard channel 101.6 mm deep with a 43.7 mm wide flange, weighing 10.8 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 C4X7.25 the computed area agrees with the published value to 0.01% and Ix to 0.03%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 37,537 mm³ |
| Elastic modulus, Sy | 5,681 mm³ |
| Plastic modulus, Zx | 46,537 mm³ |
| Plastic modulus, Zy | 11,444 mm³ |
| Radius of gyration, rx | 37.2 mm |
| Radius of gyration, ry | 11.5 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
