Parallel Flange Channel
The Parallel Flange Channel, PFC or C-channel was designed as a replacement for the Taper Flange Channel or TFC and provides a few advantages including the improved performance when using normal washers, added ease of connection and increased load-carrying capacity. During the development of the PFC the original TFC characterised by a reduction in thickness of the flanges towards the end was altered so that the thickness stayed constant from the web of the channel to the edge of the flange. The PFC has a reduced linear mass compared to the TFC and also has improved properties around the y-y axis. The PFC is typically used for lintels above doors, stair stringers, supporting floor joists, walkways and other applications where weight is to be limited and strength requirements favour one direction more than the other.
