Strut Channel is a structural system used in any metal framing job in the fields of architecture, electrical, and construction. It is a supporting tool that provides light structural support to mechanical components such as ventilation, central heating, or air-conditioning systems and wiring and plumbing systems.
Strut channels are often referred to as the manufacturer trade names such as unistrut, flexstrut, ultrastrut, etc.
Strut Channel Materials
Metal sheets are the primary components that go into the making of strut channel. Besides, they have a coat of finish given with powder coat, zinc coating, epoxy, or something else.
Stainless steel strut is manufactured for outdoor uses, where rusting might become an issue, or where it may come in contact with corrosive materials. Aluminum strut channel is also available, mainly application to the jobs where the channel has to support the extra weight. On the other hand, you can apply fiberglass struts to environments containing excessive corrosive substances.
Strut Channel Sizes
Typical strut channels come in the form of a 1-5/8 x 1-5/8 inches open box. A half-height version known as cross section is also available. These cross section struts can carry a plenty of loads across an open space or brace. So, wall-mounted positions are their primary field of application. Another version known as deep section carries a 2-7/16 x 1-5/8 inches size.
Strut channels are also categorized depending on the presence or pattern of holes. The function of holes is to facilitate mounting to walls or securing with other tools. A solid channel has no holes so you must drill them on site or use a different technique for their installation. Punch channels come with round holes, and half-slot channels have rectangular slots.
Besides, manufacturers produce strut channels in a couple of extra sizes and shapes. Sometimes, companies create new forms by welding two to four channels together for added strength and sustainability.
Uses of Strut Channel
Strut channels are mainly used in building construction. The metal structure makes it easier to support, connect, mount, and brace lightweight structural loads. Such mechanical systems that make extensive use of the tool include air conditioning, data wire, ventilation system, etc.
You can also see its use in systems that require a robust framework. Such applications include equipment racks, workbenches, etc.
The primary benefit of the use of strut channels in building construction work is that there’s no shortage of equipment for a secure connection between struts and with other items. Specially made sockets, fasteners, and bolts are available to facilitate interconnection or securing strut to fundamental building structures.
The benefits of using strut channel at a glance:
- Specially made sockets are available for easy connection
- Installation is straightforward and easy that requires only moderate skill and minimal tools
- Strut channel installation and assembly doesn’t require welding or extensive drilling and bolting, and therefore less costly
- Custom-made installation is also available
