Professional 14x12x12m Aluminum Arc Roof Stage Truss System with 12m Height and 2m PA Wings

1. Introduction

For large-scale outdoor festivals and world-class concert tours, the stage structure must be both a technical powerhouse and a visual landmark. The 14x12x12m Professional Aluminum Arc Roof Stage Truss System by DragonStage is engineered for elite production requirements, offering a 168-square-meter covered performance area. With a commanding 12-meter vertical clearance and a sleek aerodynamic arc design, this system provides the overhead volume necessary for massive lighting rigs and tiered LED displays. The inclusion of specialized 2-meter PA wings ensures that professional line array audio systems are suspended outside the main performance space, optimizing sound coverage and sightlines for the audience.

2. Challenges & Solutions

One of the primary challenges for 12-meter high structures is managing lateral wind loads and the "sail effect" of the roof canopy. DragonStage solves this with the Arc Roof geometry; the curved profile is aerodynamically superior, allowing wind to pass over the structure with significantly less lift than traditional flat designs. Another common pain point for 14-meter spans is structural deflection; our solution utilizes reinforced 6082-T6 aluminum box truss profiles that maintain a perfectly rigid line even under heavy technical loads. To prevent water accumulation during sudden storms, the arc design facilitates immediate water runoff, protecting expensive lighting and audio investments from moisture damage.

3. Key Features & Benefits

The 14x12x12m system is manufactured from aerospace-grade 6082-T6 aluminum alloy. This material is the global benchmark for professional trussing, offering an exceptional strength-to-weight ratio and natural resistance to environmental corrosion (Source:https://www.dragontruss.com/Aluminum-Truss-System-pd413987768.html).

The system utilizes a heavy-duty tower lift design with precision-engineered sleeve blocks. This allows the entire 14x12m roof grid to be rigged with lighting and cabling at waist height before being safely hoisted to its 12-meter apex. According to international safety standards for temporary event structures, the use of a synchronized ground-support tower system is the safest way to manage massive overhead loads while minimizing risks to the crew (Source:https://www.plasa.org).

To ensure a complete venue solution, this arc roof is designed for perfect compatibility with our modular aluminum stage platforms. These decks feature 18mm anti-slip surfaces and high load-bearing capacities, providing a stable foundation that matches the professional grade of the overhead rig (Source:https://www.dragontruss.com/Aluminum-Stage-Platform-pd463987768.html).

4. FAQ Section

Q: What is the benefit of an Arc Roof over a standard Pitched Roof?A: The arc design offers superior wind resistance and a more modern, "tour-grade" aesthetic, while providing excellent water drainage for large spans.

Q: How much weight can the 2m PA wings support?A: Each wing is specifically reinforced for professional audio loads. Please contact our engineering team with your speaker weights for a verified load-calculation report.

Q: Is the PVC canopy fire-retardant?A: Absolutely. Our canopies are made from 850g/m² PVC that is waterproof, UV-resistant, and meets B1/M2 fire-retardant safety standards.

Q: Can this 12-meter high structure be raised manually?A: Due to the scale and weight of the 14x12m grid, we strongly recommend using synchronized electric chain hoists for a safe and level lift.
