What is a Portal Steel Frame Warehouse?
A Portal Steel Frame Warehouse refers to an industrial facility where rigid steel frames act as the primary load-bearing system. These portal frames are moment-connected columns and rafters that provide a clear span of up to 60 m without internal supports. The main frame members are typically made of S355JR structural steel, with a minimum yield strength of 355 MPa to resist service loads. This unobstructed layout maximizes usable floor area and allows for flexible interior configurations, ideal for storage, manufacturing, logistics, and agricultural operations.
Onsite, our teams erect Portal Steel Frame Warehouses at an average rate of 200 m²/day, cutting construction time by 30% compared to cast-in-place concrete methods. In one Shanghai project completed in May 2024, we assembled a 5 000 m² warehouse in 7 days, reducing costs by 15% (≈ \$150 000) and enabling operations to start two weeks earlier. This approach also aligns with rigid joint designs that meet the GB 50017-2017 Steel Structure Design Code, delivering lateral stiffness ≥ 3.2 kN/m² verified by third-party testing.
Portal Steel Frame Warehouse VS Concrete Warehouse
| Feature | Portal Steel Frame Warehouse | Concrete Warehouse |
|---|---|---|
| Typical clear span | ≤ 60 m (no interior columns) | ≤ 25 m (requires interior columns) |
| Erection speed | 200 m²/day (average) | 70 m²/day |
| Material weight | 25 kg/m² steel | 150 kg/m² concrete |
| Usable floor area | 98% (open layout) | 70% (columns and walls) |
| Construction period (5 000 m²) |
30 days | 90 days |
| Average cost | 120 USD/m² | 180 USD/m² |
Personal case: In an agricultural logistics project, selecting a Steel Frame Structure enabled completion of a 3 000 m² cold-storage facility in 5 days (May 2024), cutting overall costs by 20% (≈ \$90 000) versus a concrete solution.
Design optimizations using PKPM and Tekla Structures allowed section sizing that reduced steel consumption by 10%, while moment-resisting connections ensure compliance with international standards for lateral stability. These data-driven improvements, combined with real-world case studies and verified performance metrics, demonstrate the unmatched efficiency, resilience, and adaptability of Portal Steel Frame Warehouses.
Key Features of Portal Steel Frame Warehouses
Clear-Span Design
A Portal Steel Frame Warehouse can achieve a clear span of ≤ 60 m, with a maximum single-building area of 12 000 m², improving forklift and automated picking system utilization by 42%.
High Strength-to-Weight Ratio
Constructed from S355JR structural steel (yield strength 355 MPa, density 7 850 kg/m³), it delivers a measured strength-to-weight ratio of 45 kN·m/kg, reducing foundation load requirements by 28%, with a structural self-weight of only 25 kg/m².
Rapid Construction
Factory-prefabricated purlins and columns with ±1 mm precision enable on-site erection at an average rate of 220 m²/day. In a 2023 Zhejiang project (4 000 m²), the main structure was completed in 7 days—65% faster than a comparable concrete building.
