Large-span Truss Roof System

Summary

Large-span Truss Roof System (For Stadiums and Arenas)

LARGE-SPAN TRUSS ROOF SYSTEM

 (FOR STADIUMS AND ARENAS)

A roof structure system specifically designed for large buildings such as stadiums and sports arenas. Its key feature is the ability to cover vast areas with a large span.

SPACE GRID STRUCTURE

Bolted Ball Joint Space Truss
Modular assembly with fast installation speed, ideal for projects with a high degree of standardization and industrialization.
Ball Joint Space Truss
High overall rigidity and structural stability, suitable for large-span or heavy-load projects.

CORE ADVANTAGES OF SPACE GRID STRUCTURES

Ultra-Large Span

The single span can reach over 150 meters, with no intermediate columns.

 
This roof system can cover an enormous area of more than 150 meters in width (or length) in a single span, without the need for any supporting columns in the middle. As a result, spectators' views are completely unobstructed, creating a spacious and open interior environment with maximum freedom of movement within the venue.

Lightweight and High Strength

The steel usage is only about one-third of that in traditional structures, with a self-weight of less than 40 kg/m².

The amount of steel used is approximately one-third of that in traditional large-span structures, significantly reducing material costs and lightening the load on the lower supporting structure.

Fast Construction

Modular prefabrication, with installation speed 50% faster than traditional structures.

All steel pipes and joint balls are prefabricated in the factory according to precise drawings, enabling bulk production. This method is at least 50% faster than the traditional on-site cutting and welding process.

Design Flexibility

Supports flat, curved, and irregular shapes.

Designers can flexibly tailor the structure to meet the architectural aesthetics of the stadium, making it possible to achieve complex and unique shapes.
Application Scenarios
Multi-purpose sports stadiums, Swimming pools / Ice rinks, Training centers and competition venues

 Delivery & Support

Design Phase
BIM Model Provision (Revit/Tekla Format) To avoid construction conflicts and reduce rework costs.

Wind and Snow Load Special Analysis Report Customized simulations based on site-specific climate data.
Construction Phase
Professional Lifting Team (100% Certified Welders)** We ensure full traceability of the entire process, with clear responsibility assigned to each individual. All operators hold the required qualifications for specialized equipment.

3D Scanning Acceptance (Deviation Control within ±3mm)** Laser scanning point clouds are compared with the design model to minimize errors, addressing the traditional ±10mm acceptance deviations that could lead to sealing issues or drainage risks.
