Function

Framing for building services

Strut channel forms trapeze hangers, wall supports, frames and stands for mechanical and electrical services.

Four depths, slotted or plain

The 41 mm width is common to every depth, so the same nuts and fittings fit all four profiles; slotted channel takes bolts through its back at regular centres.

How it works

Nuts lock under the lips

A channel nut is pushed into the open face and turned a quarter turn so its grooves sit under the in-turned lips. A bolt through a fitting is screwed into the nut and tightened, and the grooves lock the nut against the lips. The fitting can be moved along the channel before the bolt is tightened.

Common applications

Where it is used.

Application

Pipe and duct trapezes

A length of channel hung on two threaded rods carries pipes or ducts clamped to its face. Several services can share one trapeze.

Application

Cable tray and conduit supports

Electrical contractors fix cable tray and conduit to strut on walls and ceilings. The slots let supports be set to the route.

Application

Plant and panel frames

Stands for pumps, panels and rooftop units are bolted together from channel and fittings. Back-to-back channel makes the posts.

What is strut channel called in other markets?

In the US it is strut channel, and UK suppliers sell it as a channel support system. In other languages it is a profil strut in French, a Montageschiene in German, a profilo di montaggio or profilo asolato in Italian and a perfil strut in Spanish.

Should I order slotted or plain strut channel?

Slotted channel takes bolts through its back at regular centres, so brackets and fixings can go anywhere without drilling. Plain channel is stiffer and cleaner where fixings are few. Corona makes both in 21, 41, 61 and 81 mm (13/16 to 3-1/4 in) depths, 12G to 16G.
