Prefab Steel Structure House Rapid Installation For Residential Buildings

Core Technology System
Structural System: Uses a steel frame or steel frame-bracing system, meeting the seismic fortification requirements of 8 degrees, with a design service life of up to 70 years. Envelope System: 150mm thick sandwich composite insulated wall panels with a thermal conductivity ≤0.25 W/(㎡·K), meeting ultra-low energy building standards. Floor System: Combined steel truss floor deck and lightweight concrete, enabling fast installation and excellent sound insulation. Fire Protection System: Composite protection with thick-film fireproof coatings and fireproof boards, with a fire resistance rating ≥2 hours.

Core Advantages
Construction Speed: Reduces construction time by 60% compared to traditional buildings; a 1,000㎡ building structure can be completed within 30 days. Quality Precision: Factory CNC processing ensures component errors ≤2mm, achieving millimeter-level installation accuracy. Green and Low Carbon: Steel recycling rate reaches 98%, construction waste reduced by 85%, and full life-cycle carbon emissions reduced by 65%. Flexible Space: Up to 24-meter column-free span, allowing flexible interior layouts. Smart Integration: Standard photovoltaic building integration system (power generation 200W/㎡), smart home control system, rainwater harvesting device (water saving rate 40%), and fresh air heat recovery system (heat exchange efficiency ≥75%).
