Large Span Prefab Steel Structure Building with 120 km/h Wind Resistance, Magnitude 8 Seismic Resistance, and Fast Bolt Assembly for Industrial Use

Our large span prefab steel structure buildings are engineered specifically for industrial workshops and warehouses. Steel offers exceptional strength while remaining lightweight, with uniform material properties, stable mechanical performance, and excellent plasticity and toughness.

These structures are fully customizable, prefabricated in our factory and assembled on-site, enabling rapid construction, large clear spans, easy modification and clean dismantling. Manufactured by Sichuan Shunyao Supply Chain Management Co., Ltd. in Chengdu, China, utilizing Q235B and Q355B structural steel with precision fabrication processes.

• Large Clear Span Design: Portal frame design achieves clear spans up to 30 meters without intermediate columns, providing 100% usable internal space for production lines, machinery layout and forklift movement.
• Engineered for Extreme Conditions: Wind resistance up to 120 km/h (Hurricane Grade 12), seismic resistance up to Magnitude 8, and customizable snow load from 0.5 to 2.0 KN/m².
• Fast Bolt Assembly: All components pre-cut, drilled and welded in our factory, assembled with 10.9S high-strength bolts. A 2,000㎡ building can be erected in 20-30 days with a small crew.
• Eco-Friendly & Recyclable: Class A fireproof rockwool sandwich panels provide thermal and sound insulation. Main steel frame is 100% recyclable with minimal on-site environmental impact.
