Fireproof Hotel Steel Frame Building Construction Prefab Apartment Building

Our prefabricated steel structure apartments combine structural safety, energy efficiency, and rapid construction for hotel and residential applications.

• 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.

• 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.

• 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.

• 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).

• Factory Prefabrication: CNC cutting and robotic welding ensure precision (tolerance ±2mm).
• On-Site Installation: Follow "bottom-to-top, primary-to-secondary" sequence with real-time verticality monitoring (deviation ≤H/1000).
• Quality Acceptance: Ultrasonic testing (UT) for welds, 100% bolt torque inspection per GB 50205 standards.

• Weekly quality audit meetings to address processing weaknesses
• Bi-weekly employee training sessions
• ISO 9001 Quality Control System compliance
• Monthly client feedback collection for continuous improvement
• Comprehensive quality inspection reports for all production processes
