High Quality Prefabricated Steel Structure Building
Structural Safety
- Seismic Design: Flexible joints and energy-dissipating devices (e.g., dampers, BRBs) enhance energy absorption during earthquakes.
- Load Calculation: Accurately calculate dead loads, live loads, wind/snow loads, and verify compliance with local codes (e.g., GB 50009).
- Fire & Corrosion Protection: Apply intumescent fireproof coatings (fire resistance ≥2 hours) and hot-dip galvanizing or epoxy coatings.
Material Selection
- Steel Types: Q235/Q345 steel for main structures; cold-formed thin-walled steel for secondary components.
- Connection Materials: High-strength bolts (Grade 10.9) and CO₂ shielded welding ensure joint reliability.
- Auxiliary Materials: Rock wool (density ≥100kg/m³) or polyurethane sandwich panels (fire rating B1) for insulation.
Prefab Component Design
- Standardized Modules: Modular apartment units (e.g., 3m×6m) reduce production errors and improve assembly efficiency.
- Joint Optimization: Hybrid "bolt + weld" connections minimize residual stress and allow on-site adjustments.
- Transportation & Installation: Limit component size to transport regulations (e.g., height ≤4.5m) with pre-set lifting points.
Energy Efficiency
- Passive Design: Double-glazed Low-E windows and external insulation (U-value ≤0.4 W/(m²*K)) reduce energy use by 30%.
- Green Materials: Recycled steel (recovery rate ≥90%) and low-VOC paints (VOC ≤50g/L) minimize carbon footprint.
- Renewable Systems: Roof-integrated PV panels (efficiency ≥20%) and rainwater harvesting (capacity ≥50m³).
