The choice between a 30x30cm truss and a 40x40cm truss may seem trivial, but in reality, this detail can make a significant difference in the safety and efficiency of your events. According to the ANSI E1.2-2012 standard, the safety factor for rigging must be at least 5:1, which is a critical point when considering the load capacities of different trusses.

Technical differences between 30x30 and 40x40 trusses
According to the TIA-222-H standard, which requires load calculations for outdoor structures, a 30x30cm truss is generally suitable for light to medium applications, while a 40x40cm truss can support significantly higher loads, which is essential for more complex and heavy setups. Both are made of aluminum 6082-T6, known for its high strength and lightness, but the size difference directly affects the load capacity and design flexibility.
| Specification | 30x30cm Truss | 40x40cm Truss |
|---|---|---|
| Material | Aluminum 6082-T6 | Aluminum 6082-T6 |
| Certification | TÜV Rheinland | TÜV Rheinland |
| Maximum Load | 500 kg | 750 kg |
| Typical Applications | Small events, exhibitions | Concerts, large structures |
When to use each one
In our experience with over 200 annual events, the most common mistake is underestimating load needs. If you are planning an event that requires a simple structure for lights or banners, a 30x30cm truss is more than sufficient. However, for larger events involving heavy LED screens or complex sound systems, the 40x40cm truss is the safe option.
Recommendations by use case
A 40x40cm truss set may seem like a larger investment at first, but its ability to support heavier setups eliminates the need for additional reinforcements, which in the long run reduces installation costs and setup time. For a more flexible truss setup, the Adjustable Angular FS-A F34, available from $269, allows for custom angles, optimizing space and design.

Buyer decision matrix
| Your situation | Recommendation | Why |
|---|---|---|
| Small event, light load | 30x30cm Truss | Enough for lights and banners, easy to install |
| Outdoor concert, heavy load | 40x40cm Truss | Supports large LED screens and sound systems |
| Mixed event, variable setups | Adjustable Angular FS-A F34 | Allows flexibility in design and angles |
| Exhibition with complex structures | 40x40cm Truss | Greater load capacity and stability |
Choosing the right truss can be the difference between a successful event and one filled with problems. Don’t let a wrong choice compromise the safety and quality of your production.
