Wind & Earthquake Resistant Clear Span Steel Construction Building For Commercial Public Venues

Wind & Earthquake Resistant Clear Span Steel Construction Building For Commercial Public Venues

Our clear span prefab steel frame building adopts portal rigid frame, steel truss and space frame system, realizing large open space without intermediate support columns. The maximum unsupported clear span can reach 80 meters, completely breaking the space limit of traditional concrete buildings. All steel components are fully prefabricated in factory and connected by high-strength bolts on construction site, which greatly shortens construction cycle and reduces labor input.

Production & Construction Flow

Customized structural design
Engineers calculate wind load, snow load, seismic load and ground bearing capacity according to your project location, select portal frame, truss or space frame structure matching your span demand, and output complete calculation reports and construction drawings.
Factory precision processing
Cutting, welding, polishing and anti-corrosion treatment are finished in automated workshop. Each component is marked with unique serial number to ensure quick classification and assembly on site, with processing error controlled within 2mm.
On-site rapid assembly
Workers splice steel frames with high-strength bolts, no complicated welding operation. A 3000 square meters standard clear span hall can complete main frame assembly within one month.
Enclosure and auxiliary installation
Install thermal insulation roof and wall panels, drainage system, ventilation, lightning protection, doors and windows. We can also match fire protection, lighting and lifting equipment according to customer needs.

Application Scenarios

Sports venues: indoor stadium, badminton hall, gymnasium, grandstand canopy
Industrial buildings: large logistics warehouse, aircraft hangar, factory workshop, bulk material storage shed
Public venues: exhibition center, convention hall, station waiting hall, theater

FAQ

Q1: What’s the maximum clear span you can produce without middle columns?

A: Our maximum unsupported clear span reaches 80 meters. For spans over 50 meters, we will adopt space truss structure to strengthen lateral stability and wind resistance.

Q2: Is the steel frame suitable for coastal areas with salt fog?

A: Yes. We provide C5-M heavy marine anti-corrosion coating system for coastal projects, and hot-dip galvanized auxiliary purlins to extend anti-rust service life over 60 years.

Q3: How much faster is prefab clear span steel building than concrete structure?

A: The overall construction period can save 35% - 45%. Traditional concrete large-span buildings need long curing time, while steel parts only need simple bolt assembly.

Q4: Can I customize curved and arched roof shapes?

A: Fully customizable. We support arched roofs, hyperbolic special-shaped steel structures, and you can freely choose panel colors and exterior decoration styles.

Q5: Can you provide documents for local government construction approval?

A: We supply complete CE certificates, structural calculation reports, fire test documents and full drawing sets, which can be directly submitted to local construction departments for review.

Q6: What payment terms do you accept for overseas projects?

A: We accept T/T and sight L/C. Normal term: 30% deposit before production, 70% balance against bill of lading copy. Large government projects can negotiate flexible installments.

Q7: How about sound and heat insulation performance?

A: We use high-density rock wool sandwich panels, sound insulation value up to 45dB, meeting EU energy-saving standards, suitable for exhibition halls and stadiums with high environmental requirements.
