21x20x11m Professional Concert Roof Stage System with Speaker & LED Wings

  • Dragon Stage

Product Description

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.

Why Choose This Concert Roof Stage System?

Dedicated Speaker & LED Wings

Unlike traditional stage structures that suspend all equipment from the main roof, this system provides independent support structures for audio and video equipment.

Benefits include:

  • Better structural load distribution

  • Improved line array positioning

  • Larger LED display capacity

  • Easier equipment maintenance

  • Increased production flexibility

This configuration is widely adopted by professional touring companies and festival organizers.

Six-Tower Ground Support Structure

The roof is supported by six heavy-duty lifting towers, significantly increasing structural stability across the 21m × 20m span.

Compared with conventional four-tower systems, the additional support points help:

  • Reduce beam deflection

  • Increase suspended equipment capacity

  • Improve wind resistance

  • Enhance overall structural redundancy

This makes the system suitable for demanding outdoor applications.

Optimized for Touring Productions

The modular aluminum construction allows:

  • Rapid assembly and dismantling

  • Efficient transportation

  • Flexible future expansion

  • Easy replacement of individual components

The design is particularly suitable for rental companies and touring productions operating across multiple venues.
