Curved tempered fire-resistant glass partitions combine elegant architectural curves with certified fire protection (up to 30 minutes integrity). Ideal for modern spaces requiring both safety and design flexibility, such as spiral atriums and curved corridors.
Structural Innovation
Our curved fire-resistant glass partitions are engineered through precise thermal bending and tempering processes, achieving radii as tight as 300mm without compromising safety. The glass undergoes rigorous testing to meet Class A fire ratings (GB 15763.1-2009), providing both integrity (E) and insulation (I) performance. Unlike flat partitions, these curved systems maintain structural stability during fire exposure through reinforced stainless steel framing and intumescent sealants that expand at 120°C to seal gaps.
Technical Specifications
Fire Resistance: 60-120 minutes (tested per EN 1364-1)
Glass Thickness: 12-19mm laminated configuration with transparent fire-resistant gel
Curvature Tolerance: ±1.5mm across full arc length
Frame System: Powder-coated steel or aluminum alloy with melting point >800°C
Applications: Circular atriums (like Shanghai Xuhui Aerospace Project), spiral stair enclosures, curved museum galleries
Performance Advantages
Safety Compliance: Achieves both smoke separation and fire compartmentalization in curved architectures where traditional walls are impractical.
Optical Clarity: Maintains >85% light transmission (ASTM D1003) without visual distortions despite curvature.
Thermal Stability: Withstands thermal shocks during fires where surface temperatures exceed 160°C within minutes.
Customization: Supports asymmetrical shapes and hybrid designs (e.g., combined with metal panels per architectural plans).
Case Integration
As implemented in the Shanghai Xuhui Aerospace Project (referenced in your images), our curved partitions formed the iconic circular barriers surrounding the central skylight. The project demonstrated:
Rapid installation via prefabricated modular units despite complex geometry
Coordination with seismic movements in high-rise structures
Maintenance of 2-hour fire rating across all curved segments
Certifications
CE Marking (EN 13501-2)
ISO 9001:2015 quality management
Third-party tested for cyclic movement (EN 1364-3)
This solution merges uncompromised safety with sweeping visual impact, enabling architects to realize daring curves while meeting stringent fire codes. Custom engineering reports and project-specific testing data are available upon request.
