대형 스팬 공간 그리드 지붕 철골 구조
대형 스팬 공간 그리드 지붕 철골 구조
The spatial grid steel structure constitutes a spatially integrated skeletal system in which loads are distributed collectively. Composed of an orderly assembly of structural members, it is simultaneously lightweight and robust, enabling the construction of large-span, column-free spaces. Most of its components are prefabricated in a factory, facilitating convenient and rapid on-site installation and ensuring high construction efficiency; this design successfully harmonizes lightweight characteristics with high structural strength. The structure exhibits exceptional overall integrity, resists deformation over long-term use, and demonstrates outstanding and stable comprehensive performance. 3D truss system (triangular/pyramidal units) for ultra-large spans. Hollow steel sections (Q355B/ASTM A572) with bolted spherical nodes. Lightweight, high rigidity. Span 30–150m+. Hot-dip galvanized. 50+ year life. AISC/IBC compliant.

Core Features & Advantages
Large-span spatial grid roofs offer an open, airy space and a high degree of design flexibility, making them suitable for a wide range of applications. With a rational structural design and scientifically engineered load-bearing system, they provide outstanding resistance to wind, snow, and seismic forces, ensuring greater safety. Factory-manufactured components offer high precision and allow for rapid installation, significantly shortening construction schedules and reducing overall construction costs.
♦ 150m+ clear span;
♦ 30% lighter, less steel;
♦ Fast assembly;
♦ Zero maintenance, 50+ years;
♦ Any shape;
♦ Weather resistant.
Applications
Large-span spatial grid roofs offer expansive, column-free interiors. They are suitable for public cultural and sports facilities—such as stadiums, exhibition centers, and cultural and recreational hubs—and also meet the spatial demands of major transportation venues, including airport terminals and transit hubs. Furthermore, they are widely utilized in commercial and industrial structures—such as large-scale logistics warehouses, industrial plants, and aircraft hangars—thereby fully satisfying the functional and operational requirements of a diverse range of large-span buildings.
