CS289 Spigot Box Truss Overview

The CS289 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 289mm square profile, 50mm diameter aluminum round tubes and 3mm wall thickness, CS289 provides a strong and lightweight solution for applications requiring higher structural stability compared with ladder truss systems.

The integrated spigot pin connection system enables quick installation, efficient transportation and flexible combination of different truss lengths.

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 stability for lighting and roof structures;

  • Multi-directional load distribution.

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 under proper maintenance.

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.

Connection System

The CS289 adopts a spigot pin connection system.

This modular connection method provides:

Efficient Installation

Truss sections can be quickly connected without complex bolt assembly.

Flexible Configuration

Different lengths can be combined to meet various event layouts.

Easy Transportation

Modular sections simplify packing, shipping and storage.

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.
