Primary Applications
Super High-Rise Landmark Curtain Walls
Office buildings and hotels above 150m (e.g., urban CBD landmarks), strong wind load resistance
Cultural Building Curtain Walls
Special-shaped facades of museums and theaters (e.g., double curved surfaces, hollow shapes)
Old Curtain Wall Renovation
Renovation of old building curtain walls, direct replacement of original GRC/stone curtain walls, no keel modification needed
Coastal Building Curtain Walls
Coastal residences and port terminals, salt fog corrosion resistance
Performance Benefits
Sealing & Energy Saving
Air tightness ≥Class 3, reducing heat loss, building energy consumption reduced by 15%-20%
Flexible Modeling
Customizable single/double curved surfaces, reliefs and hollowing (precision ±1mm), realizing architects' creative designs
Long-Term Durability
Outdoor service life 50+ years, no corrosion or fading, annual maintenance cost ≤8 yuan/m²
Installation Process
Substrate Preparation
Curtain wall keels need leveling (error ≤1mm/m), galvanized layer of steel structure keels ≥80μm, anti-corrosion topcoat applied (thickness ≥40μm)
Mixing Preparation
Mixed with high-shear mixer (≥1400 RPM), vacuum vibration (-0.08MPa) for degassing, ensuring no surface pores
Construction
Curtain wall units installed by dry hanging, hanger spacing ≤600mm, joints sealed with weather-resistant sealant (displacement capacity ±25%), installation precision ±2mm
Finishing & Curing
Prefabricated curtain wall units cured for 7 days after production, strong wind avoided within 24 hours after installation, weather-resistant sealant construction completed within 1 week
Equipment & Tools
Construction Equipmen
- High-shear mixer
- Vacuum vibration molding machine
- Curtain wall dry hanging tools
- Laser positioning instrument
Safety Equipment
- High-altitude operation double-hook safety belt
- Dust mask (KN95 grade)
- Goggles
- Anti-static gloves
Substrate Compatibility
Compatible Substrates
- Galvanized steel structure
- Stainless steel hangers (304/316 material)
- Concrete wall (strength ≥C30)
Incompatible Substrates
- Ungalvanized light steel keels (easy to corrode)
- Aluminum alloy (easy to oxidize in long-term outdoor use)
Additive Compatibility
Silica fume
dosage 12%-15%, improving strength, extremely fine siliceous pozzolanic material that fills pores and significantly improves UHPC density, strength and durability
RecommendedInorganic colorants
≤8%, pigments made from inorganic minerals that provide long-lasting and stable color to UHPC with strong weather resistance and no easy fading
CompatibleOrganic resin prohibited
organic polymer resin material that reduces UHPC fire resistance and long-term weather resistance
Consult Technical TeamEnvironmental Conditions
Optimal Conditions
Special Considerations
- High-altitude installation prohibited in rainy and foggy days
- Avoid noon construction at high summer temperature (>35℃) to prevent accelerated curing of sealant
