Introduction
Have you ever wondered how event organisers manage to suspend heavy lighting rigs, create dramatic backdrops, or build impressive stage structures? The answer lies in the ingenious mechanical design of truss systems.
If you’re planning an event that requires a large stage or heavy equipment, understanding truss systems is crucial. They provide the structural foundation for many event setups— from stages and lighting rigs to exhibition booths.
This informational guide provides a comprehensive overview of truss systems— explaining how they work, the different types available, and why they are essential for any event that requires rigging, lighting, or complex staging.
What is a truss system?
A truss system is a specialised structural framework designed to support heavy loads and evenly distribute weight. Arranged in a triangular configuration and connected at joints called nodes, it’s primarily used to create sturdy setups for stages, lights, and sound equipment.
Truss systems combine strength and versatility, making them indispensable for both indoor and outdoor events. In fact, their modular nature allows for easy customisation and configuration, enabling event planners to design immersive setups that cater to the unique requirements of various occasions.

How do truss systems work?
The genius of truss systems lies in their ability to distribute weight efficiently, significantly enhancing the structural integrity of event staging structures.
Their triangular design ensures any forces are transferred through the diagonals to the chords, ultimately reaching the support structures. In practice, by spreading the weight across multiple points, trusses minimise stress on individual components and reduce the risk of structural failure. This allows them to handle significant loads without compromising their stability.
Truss systems also offer exceptional versatility when it comes to integrating other event equipment. Lighting fixtures, speaker systems, video screens, and even decorative elements can all be rigged onto trusses—providing a central framework for your entire event production.
How effective are trusses?
Typically composed of interconnected triangular frames for efficient load distribution, truss systems are renowned for their:
- Reliability: They are constructed from durable materials like aluminium or steel, ensuring they can withstand significant weight and external forces.
- Strength: The triangular design provides exceptional structural integrity, allowing them to support heavy loads without bending or breaking.
- Scalability: Truss systems can be configured in many shapes and sizes. This will help accommodate the unique needs of your event space and design.
What are the types of trusses?
Different types of trusses exist that are adaptable to disparate staging structures in various settings, for instance:
Stage truss system
As the name suggests, stage truss systems are specifically designed for stage setups and lighting. They are typically heavy-duty trusses built to handle the weight of lighting rigs, speaker systems, and other stage equipment.
What are the different types of stage trusses?
- Box truss: A rectangular truss with four chords and multiple diagonals, offering exceptional strength and stability for supporting heavy loads.
- Triangular truss: A versatile truss with three chords and multiple diagonals, commonly used for suspending lighting fixtures and speaker systems.
- Circular truss: A curved truss that provides a unique aesthetic appeal and can be employed for overhead arches or circular structures.

FAQ
What are the types of trusses commonly used in events?
Three main types of trusses are prevalent in event production. First, box trusses are known for their exceptional strength and ability to handle heavy loads. Second, triangular trusses are versatile and often used for suspending lighting and speakers.
Lastly, circular trusses offer a unique aesthetic and can be used for curved structures or overhead arches. Each type has its specific applications and advantages depending on the event’s needs.
Can trusses be used for small-scale events?
Absolutely. While trusses are often associated with large-scale productions, smaller, lightweight truss systems are readily available and perfectly suitable for smaller events like corporate presentations, private parties, or small-stage performances.
These smaller systems offer the same structural benefits and versatility as their larger counterparts, just on a more manageable scale.
How do I determine the number of trusses needed for my event?
Determining the correct number of trusses requires careful consideration of several factors. For instance, the total weight of the equipment being hung (including lighting, sound, and décor), the span between support points, the desired configuration, and the load-bearing capacity of the chosen truss type.
It’s crucial to consult with a qualified rigging professional or truss supplier who can perform load calculations and ensure a safe and stable setup. Overestimating is always safer than underestimating.
Which is better for events, wood or steel trusses?
For event applications, steel or, more commonly, aluminium trusses are significantly better than wood. Steel and aluminium offer superior strength-to-weight ratios, greater durability, and resistance to environmental factors like temperature and moisture changes.
Wood trusses are generally not designed for the dynamic loading and repeated setup/teardown common in event production.
What is the strongest truss shape for events?
While the triangular design inherent in all trusses provides excellent strength, box trusses are generally considered the strongest for event applications, especially when dealing with heavy loads over longer spans. The four-sided structure of a box truss provides increased rigidity and resistance to bending or twisting.
How do truss systems enhance safety in events?
Truss systems significantly enhance safety by providing a stable and secure framework for suspending equipment overhead. This minimises the risk of equipment falling, which could cause serious injury or damage.
Proper installation and load calculations are essential to ensure the truss system can safely support the intended weight. Regular inspections are also crucial for identifying any potential issues.
Can truss systems be rented?
Yes, truss system rentals are widely available from event production companies such as Doremi. Renting is a cost-effective option for events that don’t require permanent truss installations, and rental companies can also provide valuable expertise and assistance with system design and setup.
How do I choose the right truss system for my event?
Choosing the right truss system involves considering several key factors:
- Load capacity: The total weight of the equipment to be supported.
- Span requirements: The distance between support points.
- Venue limitations: Ceiling height, floor space, and rigging points.
- Budget: Rental versus purchase costs.
- Aesthetic requirements: The desired visual appearance of the truss structure.
Consulting with a professional rigging company or truss supplier is highly recommended to ensure you select the appropriate system for your specific needs.
Conclusion
Composed of interconnected triangular frames for efficient load distribution, truss systems are highly effective. Unlike solid beams that may bend or shear under pressure, trusses operate primarily under axial forces—either tension or compression. This ensures that all parts of the structure contribute equally to load-bearing.
A well-designed truss system transforms your event into a professional and memorable experience. Trusses provide the strength, flexibility, and safety required for a flawless setup—whether for a small exhibition or a large-scale outdoor concert.
As a sturdy flexible framework for hanging lighting fixtures, a truss is a worthwhile investment that ensures optimal lighting coverage. Investment in the right truss system is, therefore, mission-critical to the success of a large-scale event.
