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.

Supply Capacity
Design Capability
Design capability is the core prerequisite for supply capacity and serves as the endorsement of technical feasibility.
Maximum Design Span: 200 meters (verified through wind tunnel testing)
Seismic Resistance: Meets seismic design level of 8 (GB50011)
Manufacturing Capability
Manufacturing capacity is the solid foundation of our supply capabilities.
