Unistrut's P1000 is the original metal framing strut channel and has been used in countless applications for nearly 100 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 Unistrut Application Showcase.
Features:
- OPM pre-approved for seismic applications
- UL and CSA listed for use as a Strut-Type Channel Raceway
- Punched holes are also available for ease of installation
- Available in Pre-Galvanized (PG), Atkore Defender (DF), Hot-Dip Galvanized (HG), Plain (PL), Green (GR), Gold (ZD), Stainless Steel (SS or ST) and Aluminum (EA)
- Made in the USA
