Bafang Steel Structure is equipped with an intelligent steel fabrication production line covering laser and CNC cutting, automatic submerged arc welding, shot blasting, and anti-corrosion coating.
Steel components undergo strict inspection and non-destructive testing (NDT) according to project requirements. We can also provide component identification and numbering, export packaging, and container loading plan design.
For international projects, customers can receive complete English technical drawings, material reports, quality inspection certificates, and other project documentation.
Our technical team can provide on-site installation guidance overseas and cooperate with local construction teams to support project implementation.
Founded in 1999, Bafang Steel Structure is a professional group company specializing in steel structure research, design, manufacturing, and installation. With extensive experience in large-scale and complex projects, our steel structures have been applied in airports, railway stations, metro stations, bridges, industrial facilities, large-span structures, and offshore photovoltaic projects.
Bafang has pioneered the national application of the space frame sliding construction method, including a 276 m dual-span project, developed a steel structure mobile welding robot, and participated in the formulation of two national standards, including the Technical Requirements for Spherical Nodes in Space Grid Structures.
With an annual production capacity of 200,000 tons of steel structure components and experience serving international markets, Bafang provides reliable manufacturing and engineering support for overseas steel structure projects.
1. How is seismic resistance achieved?
Seismic-resistant detailing with bolted and welded joints, engineered to the project's seismic zone and local design code.
2. How fast can the building be installed?
Prefabrication and bolted connections reduce site work, shortening erection time compared with site-welded structures.
3. What span can this system cover?
Large-span configurations are engineered per project, with truss or portal frame options depending on span and roof loading.
4. Which steel grades are used for the frame?
Q235B or Q355B steel, CE EN 1090 fabrication, ISO 9001 quality system and AISC-aligned inspection.
5. What information do you need to start design?
Project location, building dimensions, required span, roof requirement and design standard are enough to begin the structural proposal.
6. What is included for overseas erection?
Marked components, erection drawings, anchor bolt plans, packing lists and remote technical guidance during assembly.
