Circular aluminum trusses have become increasingly popular in modern event structures because they provide unique visual effects and flexible lighting possibilities.
They are widely used in:
Concert stages
Wedding events
Exhibition displays
Corporate events
Television productions
Nightclubs
Architectural installations
Compared with traditional straight truss systems, circular trusses can create:
360-degree lighting coverage
A central visual focus
Balanced stage aesthetics
Flexible fixture arrangements
However, many customers have a common misunderstanding:
"Can a standard straight truss simply be connected or bent into a circle?"
The answer is no—not for a professional event structure.
A circular aluminum truss is not customized simply because it has a curved shape.
The real reason for customization is that every event has different requirements, including:
Stage design requirements
Lighting layout requirements
Load-bearing requirements
Installation environment
Safety considerations
Therefore, professional circular aluminum trusses are created through a complete process:
Customer Requirements → Engineering Design → Structural Solution → Custom Fabrication → Safe Event Application
Before understanding the manufacturing process, it is recommended to first understand the design principles discussed in How to Design a Circular Lighting Truss Structure for Events.
A professional custom truss project does not begin in the factory workshop.
It begins with communication between the customer and the manufacturer.
Before production, the manufacturer needs to understand:
What type of event will use the structure?
What equipment will be installed?
What visual effect is required?
Where will the structure be installed?
How will the structure be supported?
A circular truss designed for a wedding decoration is completely different from a circular lighting ring supporting professional moving lights.
Therefore, the first step of customization is not deciding how to manufacture the product.
It is understanding:
What problem does the structure need to solve?
Different event applications create different structural requirements.
For decorative applications, the main requirements may include:
Visual appearance
Lightweight structure
Easy installation
Cost efficiency
Examples:
Wedding rings
Exhibition decorations
Brand displays
For professional lighting applications, the structure must consider:
Moving head lights
Beam lights
Wash lights
LED fixtures
Cable management
The design must ensure that the truss can safely support the required equipment while maintaining the desired visual effect.
More information about lighting structures can be found in Lighting Truss Systems.
For suspended structures, additional factors must be considered:
Suspension points
Motor lifting system
Load distribution
Rigging method
A suspended circular truss is not only a lighting structure but also a temporary load-bearing system.
A circular truss may look identical from the outside, but its internal design can be completely different depending on the required load.
For example:
A 6m diameter circular truss used for decoration may only support lightweight elements.
However, the same diameter structure used for professional stage lighting may need to support:
Multiple moving heads
Heavy fixtures
Cable weight
Additional accessories
The structural design must consider:
Truss size
Tube thickness
Aluminum specification
Connection method
Suspension method
Load distribution
Therefore:
The same diameter does not mean the same structure.
The manufacturer must understand the actual working condition before selecting the correct truss configuration.
For more information about structural selection, see:
Not every customization is caused by structural requirements.
Many projects require custom fabrication because the stage designer has a specific visual concept.
Examples include:
A specific diameter above the stage
A special lighting arrangement
A unique center opening
A combination of circular and linear structures
Additional support members
The circular truss becomes part of the overall stage design.
For example, a circular lighting ring may require a center support beam because the project needs:
Additional structural stiffness
Special equipment positioning
Better load distribution
A specific visual effect
A practical example is the 6m Diameter Custom Circular Aluminum Lighting Truss Ring with Center Support Beam.
This type of structure demonstrates how a custom truss is developed according to both performance and stage requirements.
After understanding the customer requirements, the manufacturer converts the concept into an engineering solution.
The design process usually includes:
Circular truss design requires careful confirmation of:
Inner diameter
Outer diameter
Overall installation space
This is especially important for indoor venues where available space is limited.
A 6m circular truss does not always occupy only 6m of space.
The final external dimension depends on:
Truss cross-section size
Connection method
Structural configuration
This is why professional manufacturers confirm dimension definitions before production.
The required load determines the truss size.
Common choices may include:
290mm truss
390mm truss
Larger heavy-duty truss systems
A larger truss is not automatically better.
The correct selection balances:
Load requirements
Transportation
Installation efficiency
Project budget

Once the design requirements are confirmed, manufacturing begins.
Unlike straight trusses, circular trusses require special consideration because the geometry is different.
A circular truss requires:
Correct radius
Accurate curved sections
Precise connection positions
Consistent overall geometry
The goal is not only to create a circle visually.
The structure must also maintain:
Connection accuracy
Structural integrity
Installation reliability
A professionally manufactured circular truss should assemble correctly without forcing components into position.
The choice between spigot and bolt connection is not only a structural decision.
It is also an installation strategy.
Spigot systems are widely used for temporary event structures because they provide:
Fast assembly
Efficient installation
Easy alignment
Reduced setup time
They are especially suitable for:
Outdoor events
Touring productions
Rental applications
Temporary structures
Outdoor events often have strict installation schedules, making fast assembly an important advantage.
Bolt connection systems are often suitable for environments where installation space is limited.
Typical applications include:
Indoor venues
Exhibition halls
Studios
Fixed installation areas
Advantages include:
Precise connection
Compact installation requirements
Better suitability for restricted working spaces
Therefore, the selection between spigot and bolt systems depends on:
Installation environment
Assembly frequency
Available working space
Transportation requirements

Understanding Spigot, Bolt and Plate End Connections in Truss Systems
A typical custom circular truss manufacturing process includes:
The manufacturer confirms:
Application
Dimensions
Loads
Installation method
Accessories
The requirements are converted into:
Structural drawings
Manufacturing drawings
Component specifications
The curved components are produced according to the required geometry.
Accuracy is important because small errors can affect:
Assembly
Connection alignment
Final appearance
Professional welding ensures:
Structural reliability
Consistent quality
Long-term durability
For aluminum structure quality considerations, see:
Welding Quality Guide: Structural Safety, Strength and Inspection for Aluminum Systems
Before shipment, the manufacturer should confirm:
Dimensions
Connection accuracy
Surface quality
Assembly condition
A customer may say:
"I need a 6m circular truss."
However, additional information is required:
Inner diameter or outer diameter?
What equipment will be installed?
Indoor or outdoor?
Ground-supported or suspended?
A visually attractive structure still needs to satisfy:
Load requirements
Stability requirements
Installation requirements
A structure designed for outdoor touring may not be suitable for an indoor venue with limited space.
Different manufacturers may use different:
Materials
Tube thickness
Connection systems
Manufacturing standards
A circular shape alone does not define structural performance.
A custom circular truss project usually begins with a specific requirement rather than an existing product.
For example:
A customer may require:
A circular lighting structure
Specific diameter
Professional lighting support
Stable installation
The manufacturer then evaluates:
Required loads
Structural configuration
Support method
Manufacturing feasibility
The final solution may include additional structural elements, such as a center support beam, to satisfy the project's performance requirements.
The 6m Diameter Custom Circular Aluminum Lighting Truss Ring with Center Support Beam is an example of how a circular truss can be customized according to real event requirements.
Because every event has different requirements for appearance, load capacity, dimensions, and installation conditions. Custom fabrication allows the structure to meet both performance and safety requirements.
Professional circular trusses are usually not made by simply connecting straight sections. The curved geometry requires specific design and fabrication.
Usually:
Diameter requirements
Inner or outer dimension
Application
Lighting equipment load
Installation method
Indoor or outdoor environment
No. Diameter is only one factor. Load requirements, truss size, connection system, and installation conditions are equally important.
Neither is universally better. Spigot systems are often preferred for fast outdoor event installation, while bolt systems can be more suitable for indoor environments with limited installation space.
Yes, if the structure is properly designed according to the equipment load and installation requirements.

Circular aluminum truss customization is not simply a manufacturing process.
It is an engineering process that starts with understanding the customer's event requirements.
A professional manufacturer does not begin by asking:
"How do we make a circular truss?"
The first question should be:
"What does this structure need to achieve?"
From stage effects to equipment loads, from installation conditions to safety requirements, every factor influences the final design.
The purpose of custom fabrication is to create a circular truss system that is:
Visually effective
Structurally reliable
Safe to install
Suitable for the intended application
That is why professional circular aluminum trusses require custom fabrication.
