Application Scenarios of Space Frame / Steel Grid Structures
1 Sports & Stadium Facilities
Multi-purpose arenas (basketball halls, swimming pools): enclosed spherical shells providing large column-free spaces.
2 Exhibition, Convention & Cultural Buildings
Exhibition centers / convention halls: large-span, unobstructed exhibition areas.
Science museums & planetariums: spherical or curved shapes that suit thematic architectural concepts.
Theaters & concert halls: integrated with acoustic engineering to optimize sound performance.
3 Transportation Hubs
Airport terminals (e.g., Beijing Daxing Airport): large-span domes create openness and enhance daylighting.
High-speed railway stations & bus terminals: suitable for high-traffic public spaces.
4 Industrial & Commercial Buildings
Warehouses, logistics centers: lightweight, high-strength space frames for fast construction.
Shopping malls & atriums: visually striking roof structures with modern architectural aesthetics.
5 Special Applications
Coal sheds & bulk storage domes
Toll station canopies
Gas station canopies (anti-corrosion, drainage, wind-resistant design)
Football stadiums / domed fields: ideal for cold or rainy climates, enabling all-weather events.
Ice & snow sports centers: double-layer space frames with insulation for ice rinks and hockey arenas.
Common Space Frame Structural Types
| Type | Characteristics | Typical Applications |
| Single-layer spherical shell | Lightweight, economical | Small to medium stadiums, exhibition halls |
| Double-layer spherical grid | High stiffness, excellent stability | Stadiums, airports, large terminals |
| Partial / hybrid spherical shell | Flexible geometry | Domes, tower crowns, landmark roofs |
| Retractable dome system | Adjustable opening | All-weather sports venues (e.g., Wimbledon Centre Court) |
Engineering Advantages of Space Frame Systems
• Long-Span Capabilities
Effortlessly covers 50–150m or more without internal columns.
• High Structural Stability
Three-dimensional load transmission ensures superior seismic, wind, and snow-load performance.
• Fast, Efficient Construction
Factory prefabrication + on-site assembly significantly shortens construction time.
• Flexible Architectural Forms
Supports flat grids, curved shells, spherical domes, double-layer grids, and custom geometries.
• Low Maintenance, Long Service Life
Typical lifespan ≥ 50 years, with recyclable steel meeting green building standards.
