Product Description
Bafang Steel Structure provides integrated steel building solutions, combining custom engineering, precision fabrication, export packaging, and overseas installation support. We work closely with clients to ensure that every component is manufactured according to project drawings and technical specifications, helping simplify on-site assembly and improve construction efficiency.
Our steel structure solutions are suitable for office buildings, commercial developments, mixed-use buildings, and new construction or renovation projects. Depending on project requirements, we can manufacture complete structural framing systems, including primary steel members, connection components, and optional roof and wall systems, delivering coordinated solutions tailored to each project's needs.

Each steel structure building can be customized according to:
- Building dimensions and floor layout
- Structural loading requirements
- Local environmental and seismic conditions
- Roof and wall requirements
- Transportation and container loading limitations
- Local installation methods
- Project schedule and construction resources
This project-oriented approach enables the steel structure package to be prepared for more efficient transportation and assembly at the destination.
- Engineering & Detailing — Project drawings are reviewed and structural components are detailed for fabrication.
- Factory Fabrication — Steel members are cut, assembled, welded, blasted, coated, and inspected under controlled factory conditions.
- Export Preparation — Components are marked, packed, and organized according to transportation and installation requirements.
- Overseas Support — Technical personnel can provide installation guidance and coordinate with local construction teams when required.
- Shorter site construction time through factory-prefabricated components
- Reduced on-site fabrication and improved construction organization
- Large-span capability for flexible interior layouts
- High strength-to-weight ratio compared with conventional heavy structural systems
- Flexible architectural configurations for different building applications
- Recyclable steel materials supporting sustainable construction
- Adaptable structural design for different regional conditions
Project Cooperation
Bafang supports several international cooperation models, including CKD component export, complete steel structure supply, fabrication according to customer drawings, installation technical guidance, local contractor cooperation, and selected EPC services.
This enables overseas customers to combine our manufacturing capabilities with their own local engineering, construction, and installation resources.
Columns, beams and bracing are cut, drilled and welded in the factory, so site work is limited to bolting and alignment.
The high-strength frame is engineered for multi-storey projects, with column sections and bracing sized by structural calculation.
Q235B or Q355B steel, CE EN 1090 fabrication, ISO 9001 quality system and AISC-aligned inspection procedures.
Shot blasting with primer and topcoat as standard, and hot-dip galvanizing where a longer maintenance interval is required.
Components are marked, bundled by assembly sequence and packed to container limits, with a loading plan issued before dispatch.
Erection drawings, anchor bolt layout, material certificates, inspection reports, packing list and container loading plan.
