What is a strut channel?

A strut channel is a cold-formed metal framing profile used to build adjustable support systems for electrical, mechanical, plumbing, HVAC, solar and construction applications.
It is also called metal framing channel, strut framing channel, slotted channel, C channel, U channel, or channel support system. Its open slot allows installers to connect channel nuts, spring nuts, pipe clamps, conduit clamps, brackets and strut fittings without welding. Professional strut catalogs describe these systems as adjustable, reusable metal framing systems with channels, fittings and accessories for multi-purpose support applications.
