PFC - Parallel Flange Channels - Steel Channels

BS EN 10025-2 : 2004 - S275JR / S355JR / S355JO

Steel PFC Channels, frequently referred to as C-Channels, Channel Beams, or Structural Channels, are defined by their unique C-shaped profile. Featuring a single web and two parallel flanges, they are specifically designed to offer maximum rigidity while allowing for easy connection to flat surfaces. This makes them an indispensable component in modern structural framing and civil engineering where high-performance support is required. We stock a huge range of Parallel Flange Channels / PFC's available for immediate off-the-shelf delivery using our own reliable and efficient nationwide transport fleet.
 

Primary Applications & Use Cases:

Parallel flange channels act as secondary beams, joists, and lintels for commercial and residential projects.
Industrial Platforms: Supporting mezzanine floors, storage levels, and heavy-duty machinery.
In Civil Engineering they are critical for retaining walls, bridge supports, and infrastructure reinforcement.

General Facts
The C-shaped profile with parallel flanges allows for easy connection to flat surfaces, making it more versatile for secondary supports than standard beams.
They are frequently specified for retaining walls, bridge supports, and infrastructure reinforcement due to their rigidity.
Yes, the profile allows for flexible installation—oriented sideways or even upside-down—to optimize load-bearing. Always consult a structural engineer.
PFCs (Parallel Flange Channels) are preferred when you need a flat mounting surface on one side, such as for floor joists, stair stringers, or when bolting steel to a flat wall or timber. Always consult a structural engineer.
PFC (Parallel Flange Channel) is a structural steel section with a C-shaped profile. Unlike traditional channels, its flanges run exactly parallel to each other.

Why use PFC?

The uniform flange thickness allows for faster, more secure assembly in steel frames. It's high Strength offers excellent load-bearing capacity for lintels, mezzanine floors, and vehicle chassis.

Barrett Steel stocks PFCs in grades S275 and S355, fully certified to BS EN 10025.
