Product Overview
Space Truss is a three-dimensional triangulated structural system used to distribute roof loads across multiple directions. It is supplied as a project-specific solution rather than a fixed catalogue item. Geometry, member sizes, connections, protection systems and delivery segmentation are confirmed from approved documents.
The engineering and fabrication scope can coordinate perimeter supports, roof panels, skylights, services and erection towers. Early review of drawings, loads, site conditions and transport limits helps define a practical supply package and reduces interface risk.

Key Features
- Project-specific engineering: The space truss is developed around three-dimensional geometry, node forces, support movement and global stability; final member sizes and details follow approved calculations and drawings.
- Coordinated interfaces: Design and detailing account for perimeter supports, roof panels, skylights, services and erection towers, reducing conflicts during fabrication and site assembly.
- Controlled prefabrication: CNC processing, documented fit-up and controlled welding improve dimensional consistency and traceability before shipment.
- Connection detailing: Bolted, welded and bearing interfaces are coordinated with the actual load path, access, tolerances and erection method.
- Inspection planning: Material verification, dimensional checks, weld inspection and specified NDT are tied to the approved quality plan.
- Delivery-ready documentation: Member marks, packing lists, inspection records and erection information are prepared to match the agreed supply scope.

Typical Applications
01 — Large exhibition and sports halls
Suitable where the project requires three-dimensional geometry, node forces, support movement and global stability. Final suitability depends on loads, geometry, site conditions, interfaces and applicable regulations.
02 — Transport terminals
Suitable where the project requires three-dimensional geometry, node forces, support movement and global stability. Final suitability depends on loads, geometry, site conditions, interfaces and applicable regulations.
03 — Industrial and public long-span roofs
Suitable where the project requires three-dimensional geometry, node forces, support movement and global stability. Final suitability depends on loads, geometry, site conditions, interfaces and applicable regulations.
