Dead Hung Rigging

Dead Hung Rigging typically consists of steel pipe battens, individually hung or as a grid, suspended from the ceiling structure without the ability to move up and down. These battens can be suspended with cable, chain or threaded rod (see suspension hardware) and are used to hang curtain track, curtains, lights, or scenery. This type of rigging is perfect for lower ceiling heights and tighter budgets. The disadvantage is that for maintenance work it is necessary to get up to the batten as opposed to having the batten come to you.

Types of Suspensions

Suspension hangers are the hardware assemblies that suspend pipe or curtain track from the overhead structure.
The hangers are comprised of different elements, depending on the ceiling conditions and the objects being suspended. We will be happy to discuss your application, identify the proper components for the best installation, and confirm pricing for you.
There are two basic hanging assemblies, one for attachment to a steel I-beam, the other for attachment to a concrete ceiling.

Bar Joist

Bar Joists are typically constructed of back to back angle iron separated by either a diagonal member of solid rod or another angle iron member. The diagonal members will create a series of triangles or “V”s across the entire truss. The point where two diagonal members meet on the bottom of the “V” is called the panel point and will be the strongest location on the bar joist. Loads should be connected as near as possible to a panel point. This connection can be performed in a number of different ways using channel strut, compression plates, or beam clamps.

I-Beam

A Wide Flange beam is the most common I-Beam style. It’s a strong and efficient structural shape that allows for a variety of connection methods. An adjustable beam clamp or channel strut are two of the more common connection methods.

Concrete

Concrete can have several different properties depending on where and when it was poured. The two most important things to understand is the thickness of the material to determine maximum anchor embedment and the PSI of the concrete which affects the allowable load that can be applied to the material . A number of different anchors can be used in a variety of sizes for attachment to concrete. ALWAYS follow the anchor manufacturer’s installation instructions and consult a structural engineer if you are uncertain of the type and PSI of the concrete you are anchoring to.
