[Huizhou, China – November 2026] – In the construction industry, the safety of exterior wall materials is directly linked to human life and property. Guangdong Fortune Stone New Material Co., Ltd. recently announced that its flagship product, Flexible Stone, has successfully passed SGS’s most rigorous A2-s1, d0 fire rating test and 1500-hour artificial weather aging test. This dual breakthrough not only proves the exceptional stability of our material under extreme conditions but also redefines safety standards for global Facade Retrofit and high-rise construction.
A2-s1, d0 Fire Rating: More Than Fire Retardant, It’s a Lifeline
According to the SGS test report (No. SDFTS25006414R01_CN), Fortune Stone achieved the highest A2-s1, d0 classification under the GB 8624-2012 standard.
- A2 (Non-combustible): With a Total Heat of Combustion (PCS) of merely 32.5 MJ/kg and a low Fire Growth Rate Index (FIGRA) of 356.8 W/s, the material actively resists ignition and prevents the rapid spread of fire.
- s1 (Very Low Smoke): It produces minimal smoke during a fire, buying crucial evacuation time.
- d0 (Zero Flaming Droplets): It generates no flaming droplets at high temperatures, completely eliminating secondary injuries caused by “fire waterfalls.”
1500-Hour Weather Aging: Defying Extreme Sunlight and Freeze-Thaw Cycles
Exterior materials are constantly exposed to UV rays, rain, and extreme temperature fluctuations. SGS’s weather aging test (No. GZMR240601632402) simulated a highly destructive outdoor environment using a Xenon Weathering Tester.
After 1500 hours of continuous exposure, the Flexible Stone showed no cracking, swelling, or flaking, achieving a perfect 0 rating for color change. Combined with our SGS water absorption (11.3%) and freeze-thaw tests (-18°C to 50°C thermal shock), Fortune Stone demonstrates incredible resistance to UV degradation and harsh weather, making it ideal for diverse climates from the Middle East to Northern Europe.
“True building safety is about withstanding the test of sudden fire and enduring decades of sun and rain,” said the Director of Fortune Stone. “In the philosophy of Flexible Stone Engineering, we will continue to use top-tier SGS data as our cornerstone to provide the safest and most durable systems for our global clients, ensuring every Facade Retrofit project is a lifelong investment.”
