How to Choose the Right Aluminum Truss: Spigot vs. Bolt

Why Spigot vs. Bolt Truss Connections Define Stage Truss Performance

When choosing an aluminum truss system, you have to consider more than just its size or appearance. The truss connections play a decisive role in the performance and practical use of the entire structure. For most stage truss projects, the choice narrows to two primary systems: spigot truss and bolt truss. Both are designed to build reliable and professional stage structures, but each offers unique advantages that directly affect performance for specific event setups.

The Advantages of Spigot Trusses

Most people choose spigot trusses because they are quick and easy to install. Installers often prefer this connection system when time is critical, such as during a rushed exhibition, a trade show, or a temporary stage setup. The spigot truss connection allows for rapid assembly and disassembly, enabling large stage truss frames to be built or dismantled in a fraction of the time compared to bolts. This efficiency not only saves labor, but also reduces logistical challenges, especially when equipment must be transported to multiple venues within a short time. 

The Strength of Bolt Trusses

Bolt trusses, on the other hand, meet a completely different set of requirements. Large concerts, outdoor music festivals, and long-term stage constructions often require truss systems that can withstand heavy loads and unpredictable conditions. The bolt truss system creates a rigid frame that maintains its structural integrity under stress. It is exceptionally strong and durable, which is why professionals in the stage truss industry rely on it for projects involving heavy LED screens or exposure to harsh outdoor environments. Although installation takes more time, experienced event coordinators know that the extra effort results in maximum safety and long-term reliability. For heavy-duty or permanent aluminum stage truss setups, the bolt option provides unmatched stability.

Choosing Based on Event Requirements

In the end, the decision between spigot truss and bolt truss depends entirely on the event requirements. Short-term projects with frequent mobility benefit from the speed and convenience of spigot trusses, while long-term installations with demanding load capacities require the security of bolt connections. Asking practical questions—such as how many kilograms the truss must support, how long the structure needs to remain in place, and whether it will be used indoors or outdoors—helps determine the most suitable solution.

Selecting the Best Truss System for Reliable Events

Investing in an aluminum truss system means investing in safety, reliability, and efficiency. Choosing the wrong type of stage truss can lead to unnecessary costs or even safety risks. By understanding the distinct advantages of both spigot truss connections and bolt truss connections, event planners and stage designers can make informed decisions that ensure compliance with safety standards while also enhancing the success of their events. The right stage truss system provides peace of mind, delivering a structure that is stable, professional, and ready for performance.
