Understanding Spigot, Bolt and Plate-End Connections in Truss Systems
Modern truss systems are not only defined by truss size or material. The connection system is one of the most important parts of structural performance.
Different truss connections directly affect:
Structural stability
Installation speed
Transportation efficiency
Load transfer performance
Rigging safety
Reusability
Appearance of the finished system
In stage, event, exhibition, and entertainment engineering, the three most common connection systems are:
Spigot Connections
Bolt Connections
Plate-End Connections
Each connection type has different advantages depending on the project requirements.
Why Truss Connections Matter
In truss engineering, the connection area is often the most critical part of the structure.
Even if the truss members themselves are strong, poor connection design may cause:
Local structural failure
Excessive deformation
Joint instability
Connection cracking
Load transfer problems
The connection system determines how forces move between truss members and how efficiently the entire structure behaves under load.
Spigot systems are designed for rapid assembly and dismantling.
This is critical for:
Touring concerts
Temporary event structures
Rental companies
Exhibition systems
Smooth Structural Appearance
Because the connection area is compact and integrated, the finished truss line appears cleaner.
This is important for:
Stage aesthetics
LED systems
Architectural event structures
High Reusability
Spigot systems are ideal for repeated installation cycles.
What Is a Bolt Connection?
Bolt truss systems use:
Bolts
Nuts
Washers
Connection plates
to create rigid structural joints.
Bolt trusses are widely used in:
Heavy-duty stage systems
Large-span roof systems
Ninja warrior structures
Custom engineering systems
Unlike spigot systems, bolt truss connections often create a smoother continuous outer surface after tightening.
This is one reason why bolt trusses are preferred for ninja obstacle systems and climbing structures where users may touch or move along the truss surface.
