How to Choose Lighting Truss (Complete Guide for Events, Stage & LED Systems)

If you are new to lighting truss systems, start with this overview:

Answer Section

Choosing the right lighting truss depends on load capacity, truss type, event size, and installation environment. For most events, a 290mm truss is suitable for small setups, while 400mm or larger truss systems are recommended for medium to large stages, especially when supporting LED screens or heavy lighting equipment.

What Factors Determine the Right Lighting Truss?

Selecting a lighting truss is not just about size. It is a combination of structural safety, application needs, and system design. The most important that you should consult your engineer for design first.

The key factors include:

• Load capacity (equipment weight)

• Truss type (box, triangle, etc.)

• Event scale and structure

• Installation method (ground support or hanging)

• Environment (indoor or outdoor)

Step 1: Determine Load Capacity (Most Critical)

The first and most important step is calculating the total load. if you do not know, you can discuss with us.

You must consider:

• Lighting fixtures

• LED screen weight

• Audio systems

• Cables and accessories

• Dynamic loads (movement, wind)

Step 2: Choose the Right Truss Size

Typical recommendations:

• Small events → 290mm truss

• Medium events → 400mm truss

• Large events → 520mm+ truss

Step 3: Select the Correct Truss Type

Different truss types are used for different applications:

• Box truss → heavy load, large events

• Triangle truss → lightweight setups

• Circular truss → design and visual structures

• Ladder truss → simple lighting rigs

Step 4: Consider Installation Method

There are two main systems:

Ground Support System

• Safer for outdoor use

• No ceiling dependency

Hanging Truss System

• Cleaner visual effect

• Requires rigging points

Step 5: Match the Event Scenario

Different applications require different truss systems:

Outdoor Events

• Require wind resistance

• Need ground support or roof system

Step 6: Material & Quality Check

A reliable truss system should use:

• 6061-T6 or 6082-T6 aluminum

• High-quality welding

• Corrosion-resistant surface

FAQ

What is the best lighting truss size?

For most events, 400mm truss provides a good balance of strength and flexibility.

Can I use 290mm truss for large events?

It is not recommended for heavy loads or large spans.

Is aluminum truss strong enough?

Yes, high-grade aluminum truss offers excellent strength and lightweight performance.

Conclusion

Choosing the right lighting truss is a combination of engineering understanding and practical experience. By considering load, type, size, and application, you can ensure both safety and efficiency for your event setup.
