CSG290 Spigot Box Truss Overview

The CSG290 aluminum spigot box truss is a modular structural truss component designed for professional event structures, lighting systems, outdoor canopy frameworks and temporary roof structures.

With a 290mm square profile, 50mm diameter aluminum round tubes and 2mm wall thickness, CSG290 provides a lightweight and flexible structural solution for applications requiring efficient transportation, quick installation and reliable performance.

The integrated spigot pin connection system enables fast assembly, convenient dismantling and flexible combination of different truss lengths according to project requirements.

Compared with ladder truss structures, the box truss configuration provides improved torsional resistance, higher overall rigidity and multi-directional stability, making it suitable for professional lighting structures, temporary outdoor structures and event applications.

Main Features

1. Stable Box Truss Structure

Compared with single-row ladder truss systems, the box truss design provides:

  • Higher torsional resistance;

  • Better overall rigidity;

  • Improved structural stability;

  • Multi-directional load distribution;

  • Better performance for lighting and temporary structures.

2. Lightweight Aluminum Construction

The aluminum alloy structure provides:

  • High strength-to-weight ratio;

  • Easy transportation and handling;

  • Corrosion resistance for outdoor applications;

  • Long service life with proper maintenance;

  • Reduced installation workload.

3. Fast Spigot Connection

The pin connection system allows:

  • Rapid assembly and dismantling;

  • Modular extension of truss systems;

  • Reduced installation time;

  • Convenient storage and transportation;

  • Flexible configuration for different event layouts.

Engineering Considerations

For outdoor structures, the final system design should consider:

  • Total span length;

  • Applied loads;

  • Lighting equipment weight;

  • Roof covering weight;

  • Wind conditions;

  • Support positions;

  • Ground conditions.

For large-scale outdoor structures, engineering verification should be completed according to project requirements.
