Technical Advantages of GRC in Curtain Wall Engineering — Analysis of the Qinglong GRC Curtain Wall System

The GRC curtain wall system offers four major advantages: lightweight and high strength (areal density ≤50kg/m²), design freedom (double-curved surfaces achievable), Class A fire resistance, and excellent durability (service life ≥50 years). Through technical optimizations in structural calculation, connection design, waterproofing detailing, and insulation integration, the Qinglong GRC curtain wall system has been successfully applied in hundreds of curtain wall projects.

Technical specifications: wind pressure resistance ≥5.0kPa, water tightness ≥500Pa, air tightness ≤1.5m³/m·h, sound insulation ≥30dB. The GRC curtain wall of the China Zun project in Beijing withstood the test of a Category 12 typhoon with all performance intact, demonstrating outstanding technical performance.
