This Professional 20m x 20m Stadium-Grade Concert Roof System represents the ultimate in large-scale event engineering. Designed to provide a massive performance footprint and extreme vertical clearance, this structure is the definitive choice for headliner festival stages and international touring productions.
Expansive Main Performance Area: Features a primary stage footprint of 20 meters in width and 20 meters in depth, providing a vast 400-square-meter space for full orchestral setups and complex theatrical scenery.
Massive 12m Vertical Clearance: Standing at a towering 12-meter height, this system offers the necessary overhead space for multi-layered lighting rigs, massive LED video walls, and high-impact pyrotechnic effects.
Advanced 6-Pillar Support: The main body is supported by six heavy-duty aluminum pillars, ensuring maximum structural integrity and distributed load-bearing safety for heavy overhead equipment.
Dual Reinforced Speaker Wings: Includes two specialized 3m wide by 10m deep box-truss frames on either side. These wings are specifically engineered as independent PA towers to securely suspend massive line array sound systems.
Industrial Strength Construction: Fabricated from high-grade 6061-T6 aluminum alloy, offering an industry-leading strength-to-weight ratio and exceptional resistance to environmental stress.
Professional Ground Support: Equipped with reinforced base plates, high-capacity sleeve blocks, and heavy-duty outriggers to ensure rock-solid stability on varied outdoor terrain.
