Aluminum Structure for Outdoor Concert: Buying Guide and Technical Specifications
Introduction
Organizing an outdoor concert requires a reliable aluminum structure for outdoor concerts that complies with safety standards and is suited to outdoor conditions. Whether you are an organizer, equipment rental company or technical manager, the choice of structure determines the safety of the audience, artists and staff. This technical guide reviews materials, spans, load capacities and available models, with data verified by TÜV Rheinland and ISO 9001:2015 certified manufacturing.
Materials and finishes
Aluminum structures for outdoor concerts are generally made from 6082/6061-T6 alloy, recognized for its excellent strength-to-weight ratio and corrosion resistance. The main, secondary and diagonal tubes ensure the rigidity of the assembly. For example, trusses in the 29 series use main tubes of 50x3 mm, secondary tubes of 25x2 mm or 30x2 mm depending on the model, and diagonals of 20x2 mm. These characteristics guarantee a lightweight yet robust structure that is easy to assemble and disassemble.
For tents, the main structure is also made from F27 alloy (6061/T6). The covers are white PVC-coated polyester, weather-resistant, UV-resistant and B1 fire-retardant. The roof is opaque (weight ≥ 850 g/m² for the WR-PF05, ≥ 800 g/m² for the WR-PF09) and the side walls are translucent (≥ 650 g/m²). These materials provide effective protection against the elements while letting natural light through.
Stage components and accessories
To complete the structure, specific accessories are available:
- Stage stairs and trolleys: easy to handle and store, they facilitate access to the stage. See the Stage Stairs And Stage Trolleys page.
- Dance floor: made of aluminum panels with a non-slip surface and 45° edges for safety. Dimensions are 9150 mm x 100 mm x 22 mm for straight edges and 1015 mm x 100 mm x 22 mm for beveled edges. The aluminum profiles are anodized for better durability. See Dance Floor.
Truss: spans and load capacities

How to choose your outdoor concert structure?
- Define the needs: number of spectators, stage size, equipment to be suspended (sound, lighting, screens).
- Calculate the loads: use the load tables to determine the appropriate truss. Take into account permanent loads (structure, cover) and operational loads (personnel, equipment).
- Choose the span: for long spans, prefer the WRS-29 or WRS-30 square trusses, which are stronger. For small structures, ladder or triangle trusses may be sufficient.
- Plan for protection: a tent suited to the stage size and local climatic conditions.
- Check certifications: structures must be tested by an independent body (TÜV Rheinland) and manufactured according to an ISO 9001:2015 certified quality system.
Buying advice
- Material quality: prefer 6082/6061-T6 alloy for its strength and durability.
- Compliance: require TÜV Rheinland test reports for permissible loads.
- Accessories: consider stairs, trolleys and dance floors to complete the installation.
- Delivery: ensure the manufacturer ships internationally and provides complete technical documentation.
- Technical support: a manufacturer able to advise you on sizing is a guarantee of seriousness.
FAQ
Q1: What is the difference between a ladder truss and a square truss? A: The ladder truss (WRF-29) is lighter and suited to small spans and moderate loads. The square truss (WRS-29/WRS-30) offers better strength and is recommended for long spans and heavy loads.
Q2: Are the tents suitable for all climates? A: The PVC-coated polyester covers are weather-resistant and UV-resistant, and B1 fire-retardant. They are suitable for outdoor use, but it is advisable to check local safety standards.
Q3: How to determine the maximum load of a structure? A: Refer to the load tables provided for each model. These values are tested by TÜV Rheinland and take into account the span and the type of load (distributed or point).
Q4: Do you offer accessories to complete the structure? A: Yes, we offer stage stairs and trolleys, as well as aluminum dance floors with a non-slip surface. Consult the product pages for more details.
