Product Description
Bafang Steel Structure delivers customized long-span steel structure solutions for buildings that require wide roof coverage, open interior layouts, and adaptable structural configurations. Depending on project dimensions, loading conditions, and architectural requirements, the structural design may incorporate space frames, steel trusses, cable-supported systems, or long-span portal frames.
Our project workflow connects structural detailing with factory fabrication and export preparation. BIM-based 3D modeling supports coordination of member geometry and connection details, while CNC cutting and precision processing help translate approved drawings into fabricated steel components. Each member can be marked and packaged according to project documentation and transportation requirements to facilitate identification and on-site assembly.
For overseas construction projects, Bafang Steel Structure can provide assembly drawings, installation documentation, lifting plans, and remote technical assistance according to the agreed scope of work. From structural configuration to shipment preparation, solutions are developed around project-specific technical requirements, construction conditions, and delivery arrangements.

Long-span steel systems reduce the need for intermediate columns, providing more usable interior space for production lines, storage operations, spectator seating, and other building functions.
Structural configurations are selected according to span, loading conditions, stability requirements, and material efficiency. Engineering calculations help establish a suitable balance between structural performance and steel consumption.
Space frames, steel trusses, cable-supported systems, and long-span portal frames offer different solutions for varied roof geometries, building layouts, and architectural concepts.
BIM-assisted detailing, CNC cutting, precision member processing, and component marking help coordinate manufacturing with approved drawings and facilitate component identification during transportation and assembly.
Steel members are identified and packaged according to project-specific transportation and assembly requirements. Assembly drawings, lifting plans, and remote technical guidance can support overseas teams during steel structure erection.

- Industrial Workshops: Large production areas with flexible equipment layouts and fewer internal obstructions.
- Warehouses and Logistics Facilities: Expansive roof coverage for storage, material handling, and logistics operations.
- Sports Arenas and Stadiums: Wide-span roof systems designed around spectator areas and venue layouts.
- Exhibition and Convention Centers: Open interiors suitable for exhibitions, events, and temporary installations.
- Large Public Buildings: Structural solutions for terminals, halls, and other buildings with demanding spatial requirements.

Three-dimensional modeling and structural detailing help coordinate member geometry, connection locations, and fabrication information before manufacturing. The scope of modeling and drawing deliverables is agreed upon according to project requirements.
Steel members are processed according to approved fabrication drawings. CNC pipe intersection cutting can be used for applicable tubular members, while other cutting and machining methods are selected according to component geometry and connection design.
Component identification supports the matching of fabricated members with drawings, packing lists, and assembly sequences. Consistent marking helps overseas teams identify components during unloading and erection.
Packaging plans take account of component dimensions, weights, transportation conditions, container limitations, and the planned installation sequence. Where appropriate, members can be grouped and packed to support efficient unloading and on-site handling.
Bafang Steel Structure can provide assembly drawings, installation documentation, and project-specific lifting plans. Remote technical assistance helps overseas construction teams clarify component identification, assembly sequences, and technical details during installation. Site supervision and other on-site services should be confirmed separately according to project scope.
Quality inspections should be conducted at appropriate stages of fabrication to verify compliance with approved drawings, material specifications, and project requirements.
- Material Verification: Check steel grades, material certificates, and traceability records.
- Dimensional Inspection: Verify member lengths, connection positions, and fabrication dimensions against approved drawings.
- Welding Inspection: Conduct visual inspections and specified nondestructive testing in accordance with applicable project requirements.
- Surface Treatment Inspection: Check surface preparation, protective coating application, and specified coating thickness.
- Final Inspection: Verify component markings, quantities, packing lists, and export packaging before shipment.
Inspection methods, acceptance criteria, and documentation should follow the applicable project specifications and governing standards.
