StructureCalcs100 PFC
Parallel Flange Channel · AS/NZS 3679.1 · Australia / New Zealand
100 PFC is a parallel flange channel 100.0 mm deep with a 50.0 mm wide flange, weighing 8.3 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 100 PFC the computed area agrees with the published value to better than 0.01% and Ix to 0.50%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 34,706 mm³ |
| Elastic modulus, Zy | 8,009 mm³ |
| Plastic modulus, Sx | 40,270 mm³ |
| Plastic modulus, Sy | 14,372 mm³ |
| Radius of gyration, rx | 40.4 mm |
| Radius of gyration, ry | 15.9 mm |
Z is the elastic modulus and S the plastic modulus, following AS 4100. Under AISC 360 the letters are reversed.
