Custom 6m Diameter Circular Aluminum Lighting Truss Ring with Center Support Beam

Dragon Stage provides custom-designed circular aluminum truss structures for professional event lighting, exhibitions, weddings, concerts and architectural temporary installations.

This project was customized for a Portugal customer, featuring a 6-meter external diameter circular lighting truss ring with an approximate 5.42-meter internal diameter.

Unlike standard straight truss systems, circular truss structures require precise curved fabrication, accurate connection design and careful dimensional control to ensure the final ring maintains the correct geometry after assembly.

Engineering Design of Circular Lighting Truss

Custom Curved Truss Structure

Unlike conventional straight aluminum truss systems, circular truss requires customized curved sections.

The manufacturing process requires:

• Precise radius calculation

• Curved aluminum tube fabrication

• Connection alignment

• Trial assembly verification

The final structure must maintain a consistent circular shape while supporting lighting equipment.

Center Support Beam Design

One important feature of this design is the additional center straight beam.

The center beam helps to:

• Improve overall rigidity

• Reduce deformation of the circular structure

• Provide additional hanging points

• Improve transportation and installation convenience

For larger circular structures, additional reinforcement elements are often considered to balance:

• Structural stability

• Visual appearance

• Equipment loading requirements

Connection Design: Bolt and Spigot Combination

For this custom circular lighting truss, two connection methods are combined:

Bolt Connection

Bolt connections are used where higher dimensional accuracy is required.

Advantages:

• Strong connection

• Reliable alignment

• Suitable for custom structures

Spigot Connection

Spigot connections provide:

• Faster assembly

• Easy installation

• Better modularity

This combination allows the structure to maintain both:

• Structural reliability

• Installation efficiency

FAQ

Can the diameter of the circular lighting truss be customized?

Yes. Circular aluminum truss systems can be manufactured according to different diameters, loading requirements and installation conditions. How to Design a Circular Lighting Truss Structure for Events?

Is a circular truss stronger than a normal straight truss?

Not necessarily. The structural performance depends on:

• Diameter

• Truss size

• Connection method

• Load requirements

• Reinforcement design

Each project should be evaluated according to actual application.

Can lighting equipment be installed on the ring?

Yes. The circular structure is designed specifically for mounting professional lighting equipment.

What is the advantage of adding a center beam?

A center beam improves structural rigidity and provides additional support points, especially for larger diameter circular structures.

Can the circular truss be reused?

Yes. With modular connection design, the structure can be dismantled, transported and reused for different events.
