Space Frame / Roof Truss
Large-Span Structure
Lightweight bolt-ball / welded space frame systems for stadiums, airports, exhibition halls, and industrial sheds. Span up to 120m without intermediate columns. PE/PVDF coating, 15-year warranty.
Product Overview
Our space frame systems use a three-dimensional truss network of tubular steel members connected by high-strength bolt-ball joints — creating an incredibly light yet stiff structure capable of spanning 120m+ without internal support columns.
Each node is precision-machined and hot-dip galvanized, while members are cut to millimeter accuracy using CNC tube-cutting lines. The system assembles entirely on-site using simple bolted connections — no site welding required. Ideal for stadiums, airport terminals, exhibition halls, and industrial buildings requiring column-free interiors.
For complex geometries, our engineering team provides 3D BIM models (Tekla / Revit) showing every node, member, and connection. The entire roof structure is pre-assembled in factory for trial fitting before packing. Our 15-year structural warranty covers material defects and fabrication quality — backed by CE and ISO 9001 certification.
