Implementation process
Structural skeleton
 
1.Box body steel
• Material Grade: High-strength weathering structural steel (Q345B and above)
• Thickness Standard:
   - Side panel: 1.6-2.0mm (Industry standard: 1.2-1.4mm)

   - Top plate: 1.4-1.8mm (snow load resistance ≥1.5kN/m²)
   - Bottom beam: 6-8mm special channel steel (load-bearing core)
• Core Technologies:
   - Corten weathering steel optional: naturally forms a protective rust layer, requiring no maintenance
   - Galvanized layer: ≥120μm hot-dip galvanization, salt spray test >2000 hours

2. Structural Connection
• Seismic-resistant patent joint: allows ±150mm displacement without failure
• Multi-layer stacked dedicated connectors: Pre-installed in the factory, bolted in the field
• Welding process: Full penetration welds, 100% ultrasonic flaw detection
Enclosure barrier
 
1. Six layer insulation system (sectional view display)
Layer 1: Exterior layer (metal sheet/wood plastic board/custom finish)
Layer 2: Waterproof breathable membrane (breathable waterproof)
Layer 3: Main insulation layer:
   Plan A: 100mm polyurethane continuous spraying (λ=0.022W/m · K)
   Plan B: 150mm rock wool board (Class A fireproof, λ=0.036W/m·K)
   Plan C: VIP vacuum insulation board (ultra-thin and efficient, λ=0.008W/m · K)
Layer 4: Moisture proof and vapor barrier layer (humidity regulation)
Layer 5: Structural lining board (12mmOSB/calcium silicate board)
Layer 6: Interior Surface Layer (Multiple Options)

2. Climate adaptation plan
Cold zone version: insulation layer thickened by 50%+airtight layer+thermal bridge blocking design
Tropical version: Reflective insulation coating+ventilated air layer+sunshade system
High humidity version: double-layer moisture-proof+active dehumidification system
Epidermal system
1. Facade Options Library
Industrial Aesthetics Department: Original Steel Texture, Rust Art Treatment, Perforated Plate Design
Natural fusion system: anti-corrosion wood coating, bamboo and wood grille, vertical greening system

Cultural Features Series: Customized Pattern Printing, Local Material Application

2. Roof system
Flat roof: polymer waterproofing membrane, can be designed with people on board
Sloping roof: Integrated metal tiles/solar tiles
Green Roof: Lightweight Planting Roof System
Combination roof: a three in one system of solar panels, insulation, and waterproofing

3. Door and window system
Performance standard: U value ≤ 1.2W/m ² · K (European Passive House Standard)
Configuration options:
    -Broken bridge aluminum alloy window (three glass two chamber filled with argon gas)
    -Composite material energy-saving window
    -Intelligent dimming glass (one click atomization)
    -Anti theft and bulletproof upgrade options
Internal Ecology
 
1. Health Material Matrix
Wall system:
    -Basic version: asbestos free calcium silicate board (fireproof and mildew proof)
     -Comfort version: Bamboo wood fiber integrated wall panel (zero formaldehyde)
     -High end version: Natural clay coating (adjusts humidity, purifies air)
Ground system:
    -Durability preferred: SPC stone plastic flooring (100% waterproof, HDF high-density substrate)
     -Comfortable choice: Solid wood composite flooring (compatible with underfloor heating)
     -Industrial style: Self leveling epoxy+localized carpet
Ceiling system:
    -Standard configuration: Integrated ceiling (with reserved access)
    -Loft style: Bare spray painted pipeline+local sound-absorbing panel

2. Environmental and health certification
Formaldehyde emission: ≤ 0.03mg/m ³ (far below the national standard of 0.08mg/m ³)
VOC control: All coatings are water-based/UV cured
Allergen friendly: Antibacterial coating, inhibits mold growth
integrated system
 
1. Electrical and Intelligent
Pre wiring system: All pipelines are pre installed in the factory and only need to be connected on-site
Separation of strong and weak electricity: avoid interference, safety regulations
Smart Home Interface: Reserved KNX/BACnet/Wireless Protocol Interface
Photovoltaic Integration: BIPV Building Photovoltaic Integration Design

2. Water supply and drainage system
