21x20x11m Professional Concert Roof Stage System with Speaker & LED Wings
50 Reviews
Professional 21m × 20m concert roof stage system featuring an 11m aluminum roof structure, six ground support towers, two 2m speaker wings, and two 6m LED screen wings. Designed for festivals, concerts, touring productions, and large outdoor events.
This 21m × 20m concert roof stage system is engineered for professional live entertainment, combining a heavy-duty aluminum roof structure, modular stage platform, independent speaker towers, and dedicated LED screen wings into one integrated event production solution.
Unlike conventional roof truss systems that only provide lighting support, this configuration is specifically designed for large concerts and festivals where multiple production systems—including lighting, audio, and video—must operate simultaneously without compromising structural safety or audience sightlines.
The main roof structure measures 21 meters wide by 20 meters deep and reaches an overall height of 11 meters, creating a spacious covered performance area suitable for international touring productions and high-capacity outdoor venues.
To improve production flexibility, the system incorporates four independent wings:
Two 2-meter-wide speaker wings for left and right line array systems
Two 6-meter-wide LED screen wings for large-format video walls or sponsor displays
Separating the speaker arrays and LED screens from the main roof improves load distribution, simplifies rigging, and allows each production system to be optimized independently.
The complete structure integrates seamlessly with:
making it suitable for both permanent rental inventories and large touring projects.

Benefits include:
Better structural load distribution
Improved line array positioning
Larger LED display capacity
Easier equipment maintenance
Increased production flexibility
