Spigot Truss 300x300 mm Specifications: A Buyer's Guide
When planning a stage, exhibition stand, or event structure, understanding the precise specifications of a spigot truss 300x300 mm is essential. This guide explains the key technical details, load capacities, and model options available from our factory, helping you make an informed purchasing decision.
What is a 300x300 mm Spigot Truss?
A spigot truss is a type of aluminum truss that connects sections using a spigot (a male connector) and a coupler, allowing for quick assembly and disassembly. The "300x300 mm" refers to the cross-section dimensions: 300 mm wide and 300 mm high. These trusses are widely used in event staging, lighting rigs, and exhibition structures due to their strength-to-weight ratio and ease of handling.
Materials and Construction
All our 300x300 mm spigot trusses are manufactured from high-strength aluminum alloys 6082 or 6061-T6. The main tubes are 50x3 mm, providing the primary load-bearing structure. Sub tubes vary by model: 25x2 mm for ladder and square trusses, 30x2 mm for triangle and some square models, and 50x2 mm for larger square trusses. Brace tubes are typically 20x2 mm or 25x2 mm, depending on the model. These specifications ensure a robust yet lightweight structure suitable for professional applications.

Load Capacities: What the Numbers Mean
Load tables are crucial for safe design. We provide two types of loads:
- Distributed load (kg/m): The maximum uniform load per meter across the span.
- Point load (kg): The maximum concentrated load at a single point (typically the center).
For example, the WRS-29 square truss has a distributed load of 1942 kg/m and a point load of 1942 kg at a 1-meter span. At a 6-meter span, these values drop to 317 kg/m and 948 kg, respectively. Always consult the full load table for your specific span.
Here are the load tables for our 300x300 mm models (span in meters, loads in kg):

FAQ
Q: What is the difference between distributed load and point load? A: Distributed load is the maximum load per meter uniformly applied over the span. Point load is the maximum concentrated load at a single point, usually the center. Both are critical for safe design.
Q: Can I use a 300x300 mm truss for a 6-meter span? A: Yes, but the load capacity will be lower than at shorter spans. For example, the WRS-29 has a distributed load of 317 kg/m and a point load of 948 kg at 6 meters. Always check the load table.
Q: Are these trusses suitable for outdoor use? A: Aluminum is corrosion-resistant, but for outdoor use, you should consider additional protective coatings and proper maintenance. Consult with our engineers for specific recommendations.
Q: Do you offer custom lengths? A: We provide standard lengths as listed, but custom lengths may be possible. Please contact us with your requirements.
