Cut Sheet

Unistrut's P1001-3 (triple combination) is welded with three channel for additional strength. This channel is ideal for supporting large loads across long spans, offers versatility with connection points at both ends, and avoids welding on the jobsite.

This channel is commonly used for applications with heavy load requirements such as healthcare supports, lab supports with specialized HVAC systems, and general commercial structures where P1001 material has insufficient load capacities.

Product dimensions are 1 5/8" wide x 4 7/8" tall x 12 ga. thick; triple combination of our P1000 channel.

Our P1001-3 is available in the following finishes: Pre-Galvanized (PG), Plain (PL), and Hot-Dip Galvanized (HG), Green (GR), and Stainless Steel (SS).
