Safe Durable Prefabricated Steel Frame Building Construction Steel Structure Workshop
Premium Prefabricated Steel Structure Building - Cost-Effective, Safe & Durable
| Design Focus |
Description |
| 1. Structural Type |
Choose gabled frames, trusses, or space grids based on span (30-50m for single-span) and load requirements. |
| 2. Load Analysis |
Calculate dead loads, live loads (equipment/snow), wind loads (0.3-0.7kN/m²), and seismic forces per GB50017 code. |
| 3. Joint Design |
Hybrid bolt-welded connections (Grade 8.8/10.9 bolts + fillet/groove welds) ensure force transfer reliability. |
| 4. Fire & Corrosion |
Apply zinc-rich primer (≥80μm) + fireproof coating (1.5-3h rating); hot-dip galvanizing for C4+ environments. |
| 5. Foundation |
Prefer independent foundations (bearing depth <5m); use PHC piles for weak soil with settlement control ≤0.002L. |
| 6. Construction |
Modular prefabrication (±2mm precision), BIM-based collision detection, and 500-ton crane lifting. |
| 7. Materials |
Main structure: Q355B/C steel; high-strength zones: Q460; roofing: Al-Zn coated panels (yield ≥550MPa). |
| 8. Codes |
Comply with GB51022 (light steel codes) and GB50011 (seismic design). |
| 9. Cost Optimization |
Use tapered beams, vierendeel trusses, and purlin spacing optimization (≤1.5m) to reduce steel usage by 10-20%. |
| 10. Expandability |
Reserve column interfaces (e.g., stiffened brackets) and PV mounting bases (load ≥0.15kN/m²). |
Structural Adaptability
Gabled frames dominate single-layer factories (e.g., Tesla Shanghai Gigafactory's 45m-span frame). Heavy-duty plants (≥50t cranes) require lattice columns and braking trusses. Load combinations must cover extreme scenarios, such as typhoon winds (≥0.75kN/m²) and seismic forces (PGA 0.2g).
Innovative Joints & Materials
- Smart Joints: Huawei's factory uses slip-critical bolts + end-plate connections for rapid assembly.
- Weathering Steel: Baosteel's plant utilizes S355J2W steel, cutting coating costs and extending lifespan to 50 years.
Integrated Protection
- Hybrid Coatings: CATL factory applies "graphene-modified epoxy + intumescent coatings" for 2.5-hour fire resistance.
- Cathodic Protection: Magnesium anodes protect underground columns in chemical plants.
Sustainable Construction
- Green Practices: BYD's workshop reduces welding waste by 30% via BIM, with 65% bolted connections.
- BIPV Integration: LONGi's rooftop PV panels generate 1.2M kWh/year with 0.3kN/m² load capacity.
Future Trends
- Digital Twin: SANY's "Lighthouse Factory" monitors steel health via strain sensors + AI analytics.
- 3D Printing: CSCEC trials printed complex joints, slashing 40% and material waste 15%.
Multi-Story Steel Structure Warehouse
A multi-story steel structure warehouse is a multi-level building primarily constructed with steel as the main load-bearing component. It is widely used in industrial, logistics, and commercial sectors due to its flexible design, short construction period, and excellent seismic performance. It is a mainstream choice for modern storage facilities.
Material Characteristics and Properties
Steel Properties
- High Strength: Steel has high tensile and compressive strength, enabling it to bear significant loads.
- Lightweight: Compared to concrete structures, steel structures are lighter, reducing the burden on the foundation.
- Ductility: Steel is easy to shape into various forms, meeting complex architectural design requirements.
- Corrosion Resistance: Through surface treatments (e.g., galvanization, painting), steel can effectively resist corrosion.
- Fire Resistance: Steel loses strength at high temperatures, requiring fireproof coatings or boards for protection.
Structural Features
- Modular Design: Steel structure warehouses use prefabricated components, enabling quick assembly and disassembly.
- Large Span Design: The high strength of steel allows for large-span designs, providing more internal space.
- Seismic Performance: Steel's good ductility allows it to absorb energy during earthquakes, reducing structural damage.
- Environmental Friendliness: Steel is recyclable, reducing construction waste and aligning with sustainable development principles.
Application Advantages
- Fast Construction: Prefabricated components are factory-produced, and on-site installation is highly efficient.
- High Space Utilization: Multi-story design maximizes land use efficiency.
- Low Maintenance Costs: Steel structures are durable and require minimal maintenance.
