Professional 10x8x8m Arched Roof Bolt Truss System with 4m Audio Wings⁴

1. Introduction

Modern festival production requires a combination of aesthetic elegance and high-load performance. The DragonStage 10x8x8m 400mm Bolt Truss Arched Roof System is engineered to provide a commanding presence for medium-to-large scale outdoor concerts. Featuring a 10-meter front span and integrated 4-meter side wings, this system offers a total rigging width of 18 meters, providing ample space for both grand lighting designs and expansive sound projection. For event contractors, this triangle/arched roof architecture provides a classic "big stage" look while maintaining the structural rigidity necessary for high-fidelity touring productions.

2. Industry Challenges & Professional Solutions

One of the most significant challenges in outdoor rigging is maintaining structural balance when hanging heavy audio gear outside the main pillars. Traditional systems often require complex guy-wiring to offset the leverage of line arrays. Furthermore, water accumulation on large roof canopies remains a primary safety hazard during inclement weather.

DragonStage solves these issues through a specialized heavy-duty tower and wing system. By utilizing 400x400mm bolt trussing for both the main frame and the wings, the system achieves a higher moment of inertia, resisting the torque of heavy speaker clusters. The arched triangle roof design ensures that rainwater is naturally shed away from the stage center, protecting million-dollar lighting and sound inventories. The inclusion of six 2-ton manual hoists (four for the main roof and two for the wings) allows for a synchronized "ground-support" lift, ensuring crew safety by minimizing work performed at heights (Source:https://www.dragontruss.com/Aluminum-Truss-pl3962133.html).

3. Key Features & Operational Benefits

The 10x8x8m arched roof truss is a high-performance workspace designed for technical directors who require versatility.

Robust 400mm Bolt Truss Framework

The skeleton of this system is built from premium 400x400mm square bolt truss.⁵ This profile is widely recognized in the industry for its exceptional load-bearing capacity over clear spans. The 50x3.0mm main tubes provide the structural integrity needed to support not only the roof canopy but also the dynamic loads of moving head lights and LED backdrops. This modularity ensures that the structure remains a reliable long-term asset for touring professionals (Source:https://www.dragontruss.com/Stage-Truss-pl3452133.html).

Integrated 4m Sound Projection Wings

The standout feature of this system is the dual 4m wings.⁶ These wings are not mere appendages; they are structurally integrated into the pillar system with their own dedicated towers and sleeve blocks. This allows audio engineers to hang professional line array clusters at a height of 8 meters, clearing the stage of obstructions and providing superior acoustic coverage for the audience. This configuration is essential for maintaining professional sightlines and high-decibel audio quality (Source:https://www.dragontruss.com/Speaker-Truss-pl3352133.html).

Weather-Ready Arched Canopy Design

Safety in outdoor environments is paramount. The triangle/arched roof provides a steep gradient for effective drainage. Combined with a high-tension, flame-retardant PVC canopy, the system is designed to withstand standard outdoor wind and rain conditions. Every weld and bolt hole adheres to international rigging standards, and the system is fully supported by DragonStage’s TUV-verified manufacturing processes, ensuring compliance with global safety regulations (Source:https://www.dragontruss.com/TUV-Report-dc249965.html).
