StructureCalcs125 PFC
Parallel Flange Channel · AS/NZS 3679.1 · Australia / New Zealand
125 PFC is a parallel flange channel 125.0 mm deep with a 65.0 mm wide flange, weighing 11.9 kg/m. The dimensions below are the published AS/NZS 3679.1 values; the drawing is generated from them.
Parallel Flange Channels are the Australian standard channel — purlins, stringers and edge members, with parallel flanges that make bolted connections straightforward.

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 125 PFC the computed area agrees with the published value to better than 0.01% and Ix to 0.27%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 63,504 mm³ |
| Elastic modulus, Zy | 15,220 mm³ |
| Plastic modulus, Sx | 72,960 mm³ |
| Plastic modulus, Sy | 27,205 mm³ |
| Radius of gyration, rx | 51.1 mm |
| Radius of gyration, ry | 20.8 mm |
Z is the elastic modulus and S the plastic modulus, following AS 4100. Under AISC 360 the letters are reversed.
