Strut Channel is a standardized formed structural system used in construction. Strut Channel is used for light structural support of piping, plumbing, electrical and data wiring, as well as some mechanical components such as ventilation or HVAC components. Strut Channel may also be used in shelving systems and equipment racks using specially manufactured sockets to tighten the nut or bolt within the channel.
Strut Channel is easily joined together, using strut-specific bolts and fasteners, assembled with minimal tools and does not necessitate a lot of training for its use. The channel is formed from 12 or 14 gauge sheet metal and typically has a coating of paint, zinc, epoxy or other finish. In addition, for corrosive conditions, the channel can be made from stainless steel, aluminum or fiberglass.
There are several designs of strut channel including:
- Solid Channel – No holes
- Punched Channel – Round holes, large enough for 5/8” threaded rod or bolts.
- Half-Slotted Channel – Short, rounded end rectangular slots punched on 2” centers.
- Slotted Channel – Longer slots on 4” centers.
- Half Channel
The most popular strut channel sizes are 1 5/8” x 1 5/8” and 1 5/8” x 13/16”, and in special applications “deep channel” is manufactured (2 7/16” tall x 1 5/8” wide).
