Jinhongtong Group presents the JHT-PFB-EX45, a Large clear span prefabricated steel exhibition hall with column-free interior for North America projects. Manufactured under strict ISO 9001 quality control with CE-certified processes, this prefabricated steel building combines structural reliability, rapid construction and long service life, making it a trusted choice for North America exhibition buyers worldwide.

• Column Free Interior: JHT-PFB-EX45 achieves 30m to 60m clear spans, giving North America exhibition exhibition halls uninterrupted floor space.
• High Clearance Volume: Eave heights to 15m accommodate large exhibits, banners and temporary structures.
• Truss Roof System: Welded H-section trusses provide long-span capability with efficient steel usage.
• Crane Ready: Optional 20t overhead crane capacity supports rigging and heavy exhibit installation.
• ASCE 7 Compliant: Wind and snow loads are calculated to ASCE 7, meeting North American engineering requirements.
• Flexible Interior Layout: Movable partition walls and service grids allow the hall to host different event formats.

Typical applications include exhibition halls, convention centers, aircraft hangars, sports arenas, distribution centers and manufacturing plants requiring unobstructed floor space.

For North American clients, the structure is engineered to ASCE 7 wind and snow provisions, and the truss system can be adapted to accommodate mezzanines, cranes and suspended utilities.

Jinhongtong operates 170 sets of advanced fabrication equipment, including large hydraulic press brakes, CNC drilling machines, large-scale shot blasting units and ultrasonic flaw detectors. Processing follows AISC 360, Eurocode 3 and EN 1090 standards, with strict raw material inspection, precision CNC cutting, professional submerged arc welding, and full visual and UT/MT non-destructive testing before delivery. This disciplined process ensures every member arrives on site with exact dimensions and flawless coating.

Truss members are trial-fitted at the factory and marked for field assembly. Components are flat-packed with engineered packing schemes to protect long members during ocean transit.

The delivery includes ASCE 7 load calculation reports, erection drawings and a rigging guide for large-span assembly. A 10-year structural warranty applies.
