When it comes to securing channel to existing structural steel, Unistrut beam clamps are an easy, cost-effective solution. Beam clamps provide you with a simple beam-to-strut connection solution that doesn’t require welding or drilling.
Unistrut beam clamps come in a variety of styles to accommodate a range of beam styles, sizes, applications, and attachment preferences. This variety also means there are several different styles of beam clamps that can affect how channel is attached and the total load that can be secured to the beam. Here are some of the more common styles of beam clamps offered by Unistrut Service Company.
Unistrut Flange Beam Clamps
How They Work
Unistrut flange beam clamps, also known as Unistrut C style beam clamps, are named for their distinctive shape. Flange beam clamps are designed to secure channel to beams by clamping down on the flanges of a beam with a set screw. Depending on the design of the flange beam clamp, the channel is either sandwiched between the flange and the clamp or attached to the clamp with a threaded rod.
Examples
Unistrut PLF3037 thru PLF3075 Flange Clamps
Unistrut Window-Style Beam Clamps
How They Work
Unistrut window-style beam clamps secure channel to existing beams using a “window” cut out of a bent plate and a set screw. A pair of window-style beam clamps are placed on both sides of a beam and a channel is fed through the windows. Once in place, the window-style beam clamp is secured to the beam with the set screw, which also holds the channel in place.
Example
Unistrut P1796S Window Beam Clamp
Unistrut U-Style Beam Clamps
How They Work
Unistrut U-style beam clamps feature a piece of bent plate and a U-bolt that is threaded on both sides to secure channel in place. The channel is fed through the u-bolt, which is then tightened to secure both the plate to the beam and the channel to the plate. U-style beam clamps can be used to secure channel to either the underside of the beam or the inside of the beam, depending on the configuration of the clamp.
Examples
Unistrut P2785 U-Bolt Beam Clamp
Unistrut P2868 U-Bolt Beam Clamp
Unistrut J Style Beam Clamps
How They Work
Unistrut J-style beam clamps feature a hook shaped like a “J” to help them secure channel to existing beams. While other beam clamp styles are designed to use in pairs to secure both sides of a beam, J-style beam clamps are designed for use as a stand-alone clamp (unless indicated otherwise). This is possible as the hook secures the j style beam clamp to the opposite side of the beam.
Examples
Unistrut P2867 J-Bolt Beam Clamp
Unistrut P2824 J-Bolt Beam Clamp
Unistrut Column Inserts
How They Work
Unistrut column inserts are used to secure channel between the flanges of a beam. The column inserts are attached to the interior walls of the flanges with set screws, securing the channel between them for use.
Example
Unistrut P3087 Column Insert Beam Clamp
