Spatial Grid Steel Structures of Airport Terminal
The prefabricated steel structure building—designed as a space-frame workshop and warehouse—features major components that are entirely pre-manufactured at the factory before being transported to the construction site for assembly and installation. Compliant with relevant standards such as AISC, EN1090, CWB, and JIS, it ensures the regulatory compliance and reliability of the product throughout both the manufacturing and construction phases, serving as a fully prefabricated steel structure facility that seamlessly integrates the functions of workshop production and warehouse storage. Prefab steel building engineered to global standards (AISC, EN1090, CWB, JIS). Main frames: Q355B / ASTM A572 / S355JR H-sections. C/Z purlins, insulated or single-skin cladding. CNC precision, bolted assembly. Clear span up to 60m+. Hot-dip galvanized. 50+ year life. SGS/BV inspection available.
Construction of Modern Spatial Grid Steel Structure Warehouses
Core Features & Advantages
The construction of modern grid-style steel-frame warehouses has been certified to multiple international standards (such as AISC and EN 1090), ensuring reliable quality. By eliminating the reliance on internal support columns typical of traditional buildings, these structures achieve an open, unobstructed spatial layout. Their core components are prefabricated to standardized specifications in a factory and rapidly assembled on-site using bolts, significantly improving construction efficiency. Combined with a modular design philosophy, this approach not only meets current operational needs but also provides ample flexibility for future functional expansions or layout adjustments.
♦ Multi-standard certified (AISC, EN1090, CWB, JIS);
♦ 60m+ clear span;
♦ 50% faster build;
♦ Zero maintenance, 50+ years;
♦ Crane ready.
Applications
Space-frame grid steel structures are suitable for a wide range of applications. Whether in the open spaces of sports venues and convention centers, the heavy-duty operations of industrial warehouses, or the complex environments of airports and energy facilities, these structures serve as the core support for large-span construction projects thanks to their high load-bearing capacity and rapid construction.
♦ Manufacturing plants;
♦ Shopping malls;
♦ Agricultural buildings;
♦ Aircraft hangars;
♦ Sports halls;
