12 Gauge Solid Strut Channel

Unistrut's P1000 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. For application examples, refer to our Application Showcase

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.

Product dimensions are 1 5/8" wide x 1 5/8" tall x 12 ga. thick, solid. Punched holes are also available for ease of installation.

Our P1000 is available in Pre-Galvanized (PG), Unistrut Defender (DF), Hot-Dip Galvanized (HG), Plain (PL), Green (GR), Zinc Dichromate (ZD), Stainless Steel (SS or ST) and Aluminum (EA).
