Our grid steel structures ensure superior strength, durability, and seismic performance, creating iconic stadiums with efficient large-span coverage.
Detailed
Quick Details
LONG-SPAN SPACE FRAME ROOF SYSTEM
The China Stadium Roof Steel Structure is a long-span space frame system for gymnasiums and arenas. Built with high-strength steel, it offers durability, seismic resistance, and fast installation, making it ideal for modern sports facilities. We deliver projects for main arenas of multi-purpose sports stadiums, athletics halls, speed skating arenas, and large-scale performance venues.

TYPE of 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.
