Product Description
Our long-span steel structures are engineered to create large, open interior spaces with fewer or no intermediate columns, depending on the project design. Available structural systems include space frames, steel trusses, cable-supported trusses, and long-span portal frames, offering flexible solutions for industrial buildings, sports facilities, warehouses, and other large-scale construction projects.
We provide integrated steel structure services, from BIM-based 3D detailing and structural component fabrication to export preparation and overseas installation guidance. Steel members can be CNC-cut, processed with precision-intersecting line cutting, identified by component number, and packed according to the shipping and assembly requirements of each project.
With project-specific engineering and fabrication planning, our long-span steel structure systems can be adapted to different building layouts, loading conditions, architectural requirements, and applicable design standards.
Our project workflow can include preliminary structural scheme coordination, BIM-based 3D detailing, fabrication drawings, steel component manufacturing, quality inspection, export packaging, and overseas installation guidance.
Structural member sizes, connection details, roof loads, wind loads, seismic requirements, and foundation interfaces should be determined according to the specific project conditions and applicable design codes.
The available specifications below serve as preliminary reference information. Final configurations are confirmed through project-specific engineering.

- Flexible Structural Configurations: Space frames, trusses, cable-supported trusses, and portal frames can be selected according to span, loading, and architectural requirements.
- Precision Steel Fabrication: CNC cutting, intersecting-line processing, component marking, and controlled fabrication support accurate assembly.
- Export-Ready Components: Component dimensions and packaging can be coordinated with container loading, transportation, and overseas erection requirements.
- Overseas Technical Support: Assembly plans, lifting procedures, and remote technical guidance can be provided to support site installation.
Quality control is an important part of long-span steel structure fabrication. Inspection requirements should be defined by the approved drawings, project specifications, material standards, and applicable codes.
Our project quality control scope can include the following activities, subject to the agreed manufacturing and inspection requirements.
Steel grades, material identification, and available material certificates are checked against the approved material specifications and procurement requirements.
Cut steel members and processed components are checked against the relevant fabrication drawings and specified dimensional tolerances.
Welding procedures, welder qualifications, visual inspection, and other required checks are managed according to the applicable project requirements. Nondestructive testing is performed on specified welds using the required methods and acceptance criteria.
Bolted connection components, connection interfaces, and critical dimensions are checked according to the fabrication drawings and inspection plan.
Surface preparation, coating application, and coating inspection are carried out according to the specified corrosion protection system and project requirements.
Completed components are checked against the relevant inspection records, component identification, packing lists, and agreed shipment requirements before dispatch.
Inspection methods, sampling rates, acceptance criteria, and quality documentation are confirmed for each project. Inspection reports and material records are supplied according to the agreed documentation scope.
Our manufacturing scope can cover steel member processing, connection fabrication, component identification, and preparation for overseas delivery. Production arrangements are established according to the approved fabrication drawings, component dimensions, material requirements, and project schedule.
Space frames, steel trusses, cable-supported trusses and long-span portal frames, covering spans of 60–180 m for suitable configurations.
Q355B or Q355NL structural steel, fabricated under CE EN 1090 (ISO 9001 / AISC certified). Design codes are confirmed for the destination country.
Seismic-resistant detailing with bolted and welded joints, engineered to the project's seismic zone and local design code.
