A strut channel is a standardized formed steel structural system used in the construction and electrical industries for light structural support, often for supporting wiring, plumbing or mechanical components such as air conditioning or ventilation systems. The main advantage of strut channel in construction is that there are many options available for rapidly and easily connecting lengths together and other items to the strut channel, using various specialized strut-specific fasteners and bolts. It can be assembled very rapidly with minimal tools and only moderately trained labour, which reduces costs significantly an many applications. Several variations and lengths are available with different hole patterns for mounting walls and supports. A solid channel has no holes predrilled, and must either be drilled on site or mounted in another fashion. Strut channels are manufactured from steel and are available in a pre-galvanised finish.

Basic strut channel comes in the open box section, 1 5/8 by 1 5/8 inch square cross section. A half height (1 5/8 inch wide, 13/16 inch tall) cross section version is also available, used mostly where mounted directly to a wall as it has significantly less stiffness and ability to carry loads across an open space or brace. A deep channel 2 7/16 inches tall and 1 5/8 inch wide is also manufactured. The inwards-facing lips on the open side of strut channel are routinely used to mount special nuts, braces, connecting angles, and other types of interconnection mechanism or device to join lengths of strut channel together or connect pipes, wire, other structures, threaded rod, bolts, or walls into the strut channel structural system.

Cable trays are also available for larger jobs carrying, for example, a large amount of electrical cable. Cable trays are widely used in commercial environments such as offices and computer rooms and can be fitted to ceilings, walls or maybe used under raised access flooring. Ladder and ventilated trays may have solid covers to protect cables from falling objects, dust, and water. Tray covers for use outdoors or in dusty locations may have a peaked shape to shed debris including dust, ice or snow. Lighter cable trays are more appropriate in situations where a great number of small cables are used, such as for telephone or computer network cables. Large power cables laid in the tray may require support blocks to maintain spacing between conductors, to prevent overheating of the wires. Smaller cables may be laid unsecured in horizontal trays, or secured with cable ties to the bottom of vertically-mounted trays.

To maintain support of cables at changes of elevation or direction of a tray, a large number of specialized cable tray fittings are made compatible with each style. Horizontal elbows change direction of a tray in the same plane as the bottom of the tray and are made in 30, 45 and 90 degree forms; inside and outside elbows are for changes perpendicular to the tray bottom. These can be in various shapes including tees and crosses.

Our strut channels are manufactured by Unistrut, a leading manufacturer of structural support systems. Unistrut began supplying products to the Mechanical Market during the 1930's. The Original Unistrut Metal Framing system still provides today a quick, economical and easy way of building both temporary and permanent structures as required by electrical, mechanical and industrial services.

With over 65 years experience and investments Unistrut have increased the already extensive product portfolio, with a variety of Cable Management Solutions and advanced Metal Framing Systems.
