What Is a Stage Truss and How Is It Used?

A stage truss is a modular structural component used to support lighting, audio, LED screens, scenery and roof elements for temporary events. Most professional event trusses use a triangulated arrangement of main chords and diagonal braces to provide strength while keeping the structure easier to transport and assemble.

Common Stage Truss Shapes

• Square truss: widely used for lighting grids, goalposts, towers and roof structures.
• Triangular truss: used where its shape and connection orientation suit the project.
• Flat truss: often selected for lighter-duty display or support applications.
• Curved and custom truss: used for circles, arches and special event designs.

Spigot and Bolt Connections

Spigot truss uses conical connectors, pins and clips for fast assembly. Bolt truss uses bolted end plates. The two systems require their own compatible corners and accessories; parts should not be selected only because their outside dimensions look similar.

Typical Applications

Stage truss systems are used for concerts, music festivals, exhibitions, corporate events, theaters, studios, product launches and temporary outdoor structures. The required truss model changes with the span, load, support method and environment.

How to Select a Truss

Provide the structure dimensions, equipment weights, hanging positions and venue conditions. A supplier should match these requirements with a specific truss model and explain the required supports, connections and operating limitations.

A stage truss is only one part of the structure. Safe use depends on correct design, compatible components, qualified installation and inspection throughout the life of the equipment.
