Custom Engineering Steel Space Frame Structure Wide Span Roof System For Coal Storage

Long-span steel structures provide practical solutions for buildings that require extensive roof coverage, large unobstructed areas, and adaptable architectural layouts. Depending on the building's function and engineering requirements, structural systems can incorporate space frames, steel trusses, cable-supported structures, or long-span portal frames. Each configuration is selected according to the required span, loading conditions, roof geometry, and construction constraints.

Bafang Steel Structure integrates steel structure detailing, component manufacturing, and export preparation to support international construction projects. BIM-based 3D modeling helps coordinate structural members and connection details, while CNC cutting and precision fabrication prepare components in accordance with approved drawings. Component marking and organized packaging facilitate identification, shipment handling, and subsequent assembly at the project site.

To support overseas execution, we can prepare assembly documentation and lifting plans based on project requirements. Remote technical assistance is also available within the agreed service scope to help construction teams understand component arrangements, assembly sequences, and installation details.

From industrial roof systems to large public venues, our solutions are developed around the technical specifications, fabrication needs, and delivery arrangements of each project.

• Wide Roof Coverage: Create spacious interiors with fewer intermediate columns.
• Versatile Structural Options: Accommodate different building shapes, roof configurations, and functional requirements.
• Factory-Based Manufacturing: Process and identify steel members according to approved fabrication drawings.
• Planned Export Delivery: Organize component marking and packaging to suit transportation and site assembly needs.
• Project-Oriented Support: Provide technical documentation and remote installation guidance according to the agreed scope.

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.

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.
