Choosing a high-quality aluminum stage lighting truss is critical—not just for performance, but for safety, load reliability, and long-term durability. Here’s a clear, professional guide you can use (especially useful if you’re sourcing or selling trusses like TOURGO ).

1. Check the Aluminum Material (Core Quality)

The material determines strength, lifespan, and safety.

What to look for:

• ✅ 6061-T6 or 6082-T6 aluminum alloy (industry standard)
• ✅ High tensile strength + fatigue resistance
• ✅ Good corrosion resistance (for outdoor use)

 Example: 6061-T6 offers excellent strength and weldability, making it ideal for professional truss systems

Avoid:

• Unknown or recycled aluminum
• “Cheap alloy” without certification

2. Evaluate Load Capacity & Structural Design

A truss is a load-bearing structure, so this is NON-negotiable.

Key specs:

• UDL (Uniform Distributed Load) ≥ 500 kg/m² (professional level)
• Check:
  • Static load (fixed lights)
  • Dynamic load (moving heads, speakers)

 Always verify manufacturer load tables and safety factor (≥ 2:1 recommended)

3. Inspect Welding & Craftsmanship

Quality truss = precision manufacturing.

High-quality signs:

• ✔ Smooth fish-scale welding pattern
• ✔ No cracks, bubbles, or uneven joints
• ✔ Accurate alignment (no misaligned holes)

Poor welding = weak points & safety risks

4. Connection System & Compatibility

The connection determines installation speed + rigidity.

Common types:

• Spigot (pin) system → fast, common in touring
• Bolt/plate system → stronger, more rigid

 Multi-pin systems improve alignment and stability during setup

5. Dimensions & Tube Thickness

Typical professional specs:

• Size: 200mm–300mm box truss
• Main tube:
  • Diameter: 25–50mm
  • Thickness: 2–3mm

 Bigger = stronger span, but heavier & costlier
