Product Description

Long-Span Steel Structure Solutions

Long-span steel structures are engineered for buildings that require extensive roof coverage, large clear spans, and minimal internal columns. Depending on the building layout, load conditions, and architectural requirements, suitable structural systems may include space frames, steel trusses, cable-supported structures, and long-span portal frames. Each solution requires careful consideration of structural stability, load transfer, material efficiency, and construction feasibility to meet the specific demands of the project.

Bafang Steel Structure provides coordinated fabrication and export support for long-span steel structure projects, integrating structural detailing, manufacturing preparation, component processing, and shipment planning. Our workflow incorporates BIM-assisted 3D modeling, precision steel fabrication, CNC pipe intersection cutting, component marking, and export packaging to support dimensional coordination, component traceability, and efficient site assembly. We also prepare assembly drawings, installation documentation, and lifting plans according to project requirements. For overseas projects, remote technical assistance helps construction teams clarify assembly procedures, coordinate steel member installation, and address technical questions during on-site erection.
