80x25x14m Large Span Aluminum Roof Truss System for Mega Events & Temporary Structures

  • Dragonstage

Product Description

This is a large-span aluminum roof truss system measuring 80m long × 25m wide × 14m high, designed for mega events, stadium-scale structures, and temporary covered spaces, providing high load capacity, modular scalability, and structural safety.

This large-span aluminum roof truss system is engineered for mega-scale event infrastructure, offering a structural solution for concerts, exhibitions, sports events, and temporary architectural coverage.

With an overall dimension of 80 meters length, 25 meters width, and 14 meters height, this system creates a fully covered space capable of supporting lighting rigs, LED screens, audio systems, and roofing materials while maintaining structural stability under complex load conditions.

Unlike small or medium truss systems, this structure belongs to the category of advanced roof truss systems, where load distribution, wind resistance, and modular expansion are critical. You can explore foundational systems in roof truss systems and broader truss systems.

From an engineering perspective, such a large-span structure must strictly follow principles outlined in load analysis for modular stage systems and safety standards and engineering constraints. These ensure the system can safely handle:

  • Distributed roof loads

  • Dynamic loads from lighting and suspended equipment

  • Environmental forces such as wind and rain

The system is built using modular truss components following modular system logic, allowing scalable configuration and efficient transportation despite its large size. Installation processes can be understood through installation methodology.

This type of structure is widely used in:

  • Stadium concerts and large music festivals

  • Exhibition halls and temporary pavilions

  • Sports event infrastructure

  • Large-scale brand events and ceremonies

Explore applications in concert & event solutions and architectural temporary structures.

Material selection is critical for such large systems. High-strength aluminum alloy ensures both load capacity and weight efficiency, as explained in certified aluminum materials and aluminum structural comparison.
