Unistrut Solid Strut Channel is the original metal framing strut channel and has been used in countless applications for over 90 years. Commonly known as 12 Gauge Standard or Deep Strut Channel, it is the global standard for strut metal framing. This channel is commonly used for trapeze supports, seismic bracing, ceiling grids, pipe, conduit, duct and cable tray supports, racks, and other general framing. The P1000 is OPA approved for seismic bracing and will be included in our upcoming OPM. It is also UL Listed and CSA Listed for use as a Strut-Type Channel Raceway.
