Product Description

Long-span steel structures provide engineered solutions for buildings that require expansive roof coverage and unobstructed interior layouts. Depending on project requirements, structural options may include spatial grid systems, trussed frameworks, tension-supported beam systems, and long-span portal frames. Each configuration can be developed to balance load-bearing performance, architectural requirements, and the practical demands of construction.

Bafang Steel Structure supports overseas projects through a coordinated process covering structural detailing, component fabrication, and export preparation. Our capabilities include BIM-assisted 3D modeling, precision steel member processing, CNC intersecting-line cutting, component identification, and transport-oriented packaging. To facilitate on-site execution, we also develop assembly documentation and lifting plans, complemented by remote technical support to help overseas construction teams coordinate component assembly and installation.

FAQ
1. What types of long-span steel structures can you manufacture?

We manufacture space frames, steel trusses, string-supported beam structures, and long-span portal frames. Structural selection is based on span requirements, loading conditions, architectural design, and project constraints.

2. Are steel structures with spans of 60–180 meters available?

Long spans within this range may be feasible depending on the structural system and project conditions. Final specifications are determined through engineering analysis and project-specific design.

3. What steel grades and design codes do you support?

Q355B and Q355NL steel grades are available subject to project specifications. Design codes, material requirements, and inspection standards can be coordinated according to the applicable regulations in the destination market.

4. Do you offer export packaging and overseas installation assistance?

Yes. Our services can include component marking, export packaging, packing lists, assembly drawings, erection planning, and remote technical support, depending on the agreed project scope.

5. What details are required to request a quotation?

Please share the project location, building dimensions, required span, available drawings, roofing specifications, applicable design standards, and delivery destination. These details help us evaluate the project and prepare a more accurate quotation.
