When designing a truss structure, the relationship between span distance and load capacity is one of the most important engineering factors.

As the span increases, the truss requires stronger materials, larger profiles, and additional reinforcement to maintain safety and stability.

1. What Is Span in Truss Systems?

The span refers to the unsupported distance between two support points.

Examples:

• Stage roof width
• Exhibition booth opening
• Lighting truss bridge
• LED screen hanging structure

Longer spans create:

• Higher bending force
• Increased deflection
• Greater structural stress

2. Typical Span & Load Capacity Reference

The following data is for general reference only. Actual load capacity depends on truss type, material, connection system, and installation conditions.

3. Small Span Truss Solutions (2m–6m)

Best for:

• Exhibition booths
• Retail displays
• Small lighting rigs
• Background frames

Advantages:

• Lightweight
• Fast installation
• Economical transportatio

4. Medium Span Truss Solutions (6m–12m)

Best for:

• Product launches
• Wedding stages
• Corporate events
• Medium LED screen support

Advantages:

• Strong stability
• Flexible modular design
• Suitable for indoor & outdoor use

5. Large Span Truss Solutions (12m–24m+)

Best for:

• Concert stages
• Festival roof systems
• Outdoor performances
• Large LED walls

Advantages:

• High load-bearing capacity
• Long-distance coverage
• Professional engineering support required

6. Key Factors Affecting Load Capacity

Truss Profile Size

Larger profiles provide:

• Higher strength
• Better bending resistance
• Greater span capability

Material Type

Common materials:

• 6061-T6 Aluminum
• 6082-T6 Aluminum

Higher-grade aluminum improves:

• Tensile strength
• Durability
• Corrosion resistance

Connection Method

Professional spigot or bolt connections improve:

• Structural stability
• Safety performance
• Assembly efficiency

Wind & Outdoor Conditions

Outdoor structures must consider:

• Wind load
• Rain conditions
• Uneven ground support

Large outdoor stages often require:

• Ground support towers
• Ballast systems
• Roof reinforcement
