Prefab Multi Storey Steel Frame Construction for Warehouses

This three-floor steel frame structure building is designed for garment factory applications. The structural members consist of steel beams, columns, and trusses made from high-quality steel plates. The steel structure offers superior rigidity, seismic performance, fast construction speed, light weight, and high load-bearing capacity, making it ideal for large-span and high-rise buildings that would traditionally use reinforced concrete structures. Components are connected using welds, bolts, or rivets.

Qingdao Ruly Steel Engineering Co., Ltd specializes in steel structure fabrication and construction for both light and heavy steel projects, offering comprehensive services including design, fabrication of all structural components and insulation panels, and on-site installation.

Our fabrication facility spans 35,000㎡ with 20,000㎡ of workshop space. Equipped with three light/heavy H steel production lines, BOX production lines, C/Z purlin production lines, and various profiling steel sheet machines, we utilize advanced equipment including plasma cutting machines for precision fabrication.
