Event aluminium structure rental: technical guide to choosing your truss
Event aluminium structure rental: what the professional buyer must check
In the events industry, aluminium structure rental rests on three pillars: the geometry of the structure, the material of the profile and certified load data. For a supplier buying equipment intended for rental, every decision translates into safety, operating cost and versatility. This guide details the technical points to check before ordering, with the actual models and load values from our catalogue.
1. Understanding truss families
Aluminium structures fall into two main families: spigot truss and tent-type structures. Spigot truss are distinguished by their section: ladder, triangle, square. The choice depends on the span, suspended loads (lighting, sound, screens) and the aesthetics of the build.
- Ladder truss (WRF-29): lightweight, ideal for short spans and decorative or reinforcement applications. Main tube 50x3 mm, sub-tube 25x2 mm, diagonals 20x2 mm, material 6082/6061-T6. Available lengths: WRF-29-050 (50 cm), WRF-29-100 (100 cm), WRF-29-150 (150 cm), WRF-29-200 (200 cm), WRF-29-250 (250 cm), WRF-29-300 (300 cm). WRF-29 Ladder Truss product page
- Triangle truss (WRT-29): more rigid than the ladder, suited to arches and moderate loads. Main tube 50x3 mm, sub-tube 30x2 mm, diagonals 20x2 mm, material 6082/6061-T6. Lengths: WRT-29-050 (50 cm) to WRT-29-400 (400 cm). WRT-29 Triangle Truss product page
- Square truss (WRS-29, WRS-30, WRS-40, WRS-4060): the square section offers superior torsional resistance and allows longer spans. The models differ in tubes and diagonals.

2. Reading load tables
The load capacities below come from our TÜV-tested factory data. They indicate the distributed load (kg/m) and the point load (kg) according to the span. These values assume support conditions compliant with good practice; they do not replace a structural calculation for a specific project.
WRF-29 Ladder Truss
| Span (m) | Distributed load (kg/m) | Point load (kg) |
|---|---|---|
| 1 | 990 | 990 |
| 2 | 340 | 340 |
| 3 | 168 | 115 |
| 4 | 87 | 43 |
| 5 | 51 | 20 |
| 6 | 26 | 10 |
WRT-29 Triangle Truss
| Span (m) | Distributed load (kg/m) | Point load (kg) |
|---|---|---|
| 3 | 371 | 557 |
| 4 | 250 | 500 |
| 5 | 139 | 348 |
| 6 | 109 | 327 |
| 7 | 85 | 298 |
| 8 | 67 | 268 |
WRS-29 Square Truss and WRS-30 Square Truss (same values)

| 4 | 732 | 680 |
| 5 | 465 | 644 |
| 6 | 320 | 612 |
| 7 | 232 | 585 |
| 8 | 176 | 560 |
WRS-4060 Square Truss
| Span (m) | Distributed load (kg/m) | Point load (kg) |
|---|---|---|
| 4 | 805 | 1610 |
| 5 | 560 | 1400 |
| 6 | 403 | 1209 |
| 7 | 301 | 1054 |
| 8 | 247 | 988 |
| 9 | 210 | 945 |
For rental, these tables are essential: they allow a quick response to a request for an arch or technical grid without unnecessary over-engineering.
3. Tent-type structures: the WR-PF05
For outdoor events, the aluminium structure tent offers an alternative to truss. The WR-PF05 Top-curved Structure Tent uses a main profile in F27 aluminium alloy (6061/T6). The roof pitch is 18°. The cover is PVC-coated polyester fabric, white, weather-resistant, UV-resistant and flame-retardant B1. The roof is opaque, with a weight of ≥ 850 g/㎡; the side walls are translucent, with a weight of ≥ 650 g/㎡. WR-PF05 product page

4. Dance floors and finishes
A dance event requires a suitable floor. Our Dance Floor uses aluminium edges. The dimensions are: straight edge 9150 mm x 100 mm x 22 mm; angled edge 1015 mm x 100 mm x 22 mm. The surface is anti-slip, with a 45° safety edge (grooved anti-slip surface, 45° angle cut). The aluminium bars are all anodised. Dance Floor product page
5. Buying advice for rental
- Check certificates: our structures are TÜV Rheinland tested and our factory is ISO 9001:2015 certified. Request the reports for your safety files.
- Prioritise compatibility: spigot ends facilitate quick assembly and disassembly, a key criterion for rental.
- Plan for transport: standard lengths (50 cm to 400 cm) and square sections store and ship efficiently.
- Train the teams: reading load tables prevents overloads and poor configurations.
- Buy direct from the factory: this simplifies traceability of materials and tests.
FAQ
Q: Which truss should I choose for a 6 m span with 300 kg distributed? A: The WRS-29 or WRS-30 supports 317 kg/m at 6 m under distributed load, which covers this need. Always check the exact configuration.
Q: Are the truss compatible with each other? A: The models in the 29 series share the same spigot pitch, but the sections and tubes differ. Contact us for mixed assemblies.
