Drawing Information

CS389 Spigot Box Truss Overview

The CS389 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 389mm square profile, 50mm diameter aluminum round tubes and 3mm wall thickness, CS389 provides a strong and stable structural solution for applications requiring higher load capacity, improved rigidity and reliable performance in professional event structures.

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

Compared with smaller box truss systems, the CS389 provides increased structural depth, improved torsional resistance and enhanced stability, making it suitable for larger lighting structures, outdoor roof systems and professional event applications.

Main Features

1. Strong 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 outdoor roof and lighting 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.
