Spigot Truss Price Per Meter: A Buyer's Guide to Cost Factors and Specifications

When sourcing aluminum truss for events, exhibitions, or permanent installations, one of the first questions buyers ask is: What is the spigot truss price per meter? While pricing varies by supplier, understanding the technical factors that influence cost helps you make an informed decision. This guide breaks down the key specifications, load capacities, and practical considerations that determine the value of a spigot truss system.

What Is a Spigot Truss?

A spigot truss (also called a pin truss or cone truss) uses conical connectors that slide into the ends of each truss section, secured by a locking pin. This design allows for quick assembly and disassembly, making it popular for touring, staging, and temporary structures. The price per meter typically reflects the truss's cross-section, tube sizes, material grade, and the precision of its welding and machining.

Key Specifications That Affect Spigot Truss Price Per Meter

1. Material Grade and Tube Dimensions

All trusses in our lineup use 6082/6061-T6 aluminum alloy, which offers a good balance of strength, weight, and corrosion resistance. The main tubes, sub tubes, and brace tubes vary in diameter and wall thickness, directly impacting load capacity and cost. For example:

• WRF-29 Ladder Truss uses main tube 50x3mm, sub tube 25x2mm, and brace tube 20x2mm.
• WRT-29 Triangle Truss uses main tube 50x3mm, sub tube 30x2mm, and brace tube 20x2mm.
• WRS-40 Square Truss uses main tube 50x3mm, sub tube 30x2mm, and brace tube 25x2mm.

Thicker walls and larger diameters increase material usage, thus raising the cost per meter. However, they also provide higher load ratings, which may be necessary for larger spans or heavier equipment.

2. Truss Profile and Cross-Section

Spigot trusses come in various profiles—ladder, triangle, square, and rectangular. Each offers different load characteristics and price points:

• Ladder truss (WRF-29) is lightweight and often used for lighting or audio suspension where loads are moderate.
• Triangle truss (WRT-29) is a common choice for roof structures and ground support systems.
• Square truss (WRS-29, WRS-30, WRS-40, WRS-4060, WRS-52, WRS-5060) provides higher torsional rigidity and is suitable for heavy loads and long spans.

The larger the cross-section (e.g., 520x520mm for WRS-52), the more aluminum is used, directly increasing the price per meter.

3. Load Capacity and Span

Load capacity is a critical factor in truss selection and often correlates with price. TÜV-tested load tables provide distributed and point loads for each span. For instance:

• WRF-29 Ladder Truss at a 3m span supports 168 kg/m distributed and 115 kg point load.
• WRT-29 Triangle Truss at a 6m span supports 109 kg/m distributed and 327 kg point load.
• WRS-29 Square Truss at a 6m span supports 317 kg/m distributed and 948 kg point load.

Higher load ratings typically require more material or a larger profile, increasing the cost per meter. Always match the truss's load capacity to your actual requirements—over-specifying can inflate costs unnecessarily.

4. Available Lengths and Customization

Standard lengths range from 50 cm to 400 cm, depending on the model. For example, WRF-29 offers lengths from 50 cm to 300 cm, while WRT-29, WRS-29, WRS-30, WRS-40, WRS-4060, WRS-52, and WRS-5060 offer up to 400 cm. Custom lengths may be available but can affect pricing due to additional fabrication and machining.

Comparing Popular Spigot Truss Models

Here’s a quick comparison of the models we offer, with links to their detailed pages:

Model	Profile	Main Tube (mm)	Sub Tube (mm)	Brace Tube (mm)	Max Length (cm)
WRF-29	Ladder	50x3	25x2	20x2	300
WRT-29	Triangle	50x3	30x2	20x2	400
WRS-29	Square	50x3	25x2	20x2	400
WRS-30	Square	50x3	25x2	20x2	400
WRS-40	Square	50x3	30x2	25x2	400
WRS-4060	Square	50x3	50x2	30x2	400
WRS-52	Square	50x3	50x2	25x2	400
WRS-5060	Square	50x3	50x2	30x2	400

Note: WRS-29 and WRS-30 have identical load tables, but they may differ in other specifications (e.g., welding details or finish). Always verify with the manufacturer.

How to Estimate Spigot Truss Price Per Meter

While we cannot provide specific pricing, you can estimate cost by considering:

1. Material weight: Heavier trusses (larger tubes, thicker walls) cost more per meter.
2. Profile complexity: Ladder trusses are generally simpler and cheaper than square trusses.
3. Load requirements: Higher load capacity often means more material.
4. Surface finish: Anodized or powder-coated finishes add cost but improve durability.
5. Quantity and packaging: Bulk orders may reduce per-unit cost, but this varies by supplier.

Sourcing Tips for Spigot Truss

• Verify certifications: Look for TÜV-tested load data and ISO 9001:2015 quality management certification.
• Check material grades: 6082/6061-T6 is a common, reliable choice.
• Consider the full system: Connectors, clamps, and bases also affect total project cost.
• Request load tables: Always get official load tables for the exact model and span you plan to use.

FAQ

1. What is the typical price range for spigot truss per meter?

Pricing varies widely based on specifications, quantity, and supplier. Factors like tube size, profile, and material grade significantly influence the cost. Contact manufacturers directly for quotes based on your specific requirements.

2. How do I choose between ladder, triangle, and square truss?

Consider your load needs and span. Ladder trusses are lightweight and suitable for moderate loads. Triangle trusses offer good strength for roof structures. Square trusses provide higher rigidity and are ideal for heavy loads and long spans. Refer to the load tables for each model.

3. Can I get custom lengths?

Many manufacturers offer custom lengths, but this may affect price and lead time. Standard lengths are typically more cost-effective. Check with the supplier for availability.

4. What does TÜV-tested mean?

TÜV is a German certification body that tests products for safety and performance. TÜV-tested load tables indicate that the truss's load capacities have been independently verified, providing confidence in its structural integrity.
