Can UHPC Curtain Wall Panels Achieve a Class A Fire Rating? Analysis and Application Discussion

Building safety starts with fire protection. In modern architectural design, the fire performance of curtain wall materials has become one of the core indicators for measuring a building's safety level. As an industry leader in UHPC/GRC/GRG/GRP materials, Qinglong Group draws on 28 years of full-chain experience to provide an in-depth analysis of the fire performance of UHPC curtain wall panels, offering professional solutions for designers and building owners.

The Inherent Fire Resistance of UHPC Curtain Wall Panels: The Inevitability of Class A Fire Rating from a Material Properties Perspective

UHPC (Ultra-High Performance Concrete), a representative of new decorative building materials, owes its fire performance to its unique material composition. With cement, quartz sand, and steel fibers as its main components and free of organic combustible substances, it forms a dense structure after high-temperature calcination that effectively blocks the spread of flames. According to the T/CBMF171-2022 standard 'Ultra-High Performance Concrete (UHPC) Exterior Wall Panels,' the combustion performance of UHPC curtain wall panels reaches Class A1 as specified in GB8624-2012, i.e., non-combustible material, fundamentally meeting the fire protection requirements of high-rise building curtain walls. During its participation in drafting this standard, Qinglong Group optimized the mix ratio through 58 patented technologies, enabling the product to achieve a fire resistance limit of over 3 hours while remaining lightweight and high-strength (compressive strength ≥150MPa), outperforming traditional stone curtain walls.

Practical Verification of Fire Performance: Full-Chain Assurance from Laboratory to Construction Site

As a national high-tech enterprise, Qinglong Group has established a comprehensive fire performance testing system. At its production base in Nanning, Guangxi, every batch of UHPC curtain wall panels undergoes fire resistance testing in accordance with the GB/T9978.1-2008 standard, simulating the temperature field distribution in real fire scenarios. In the renovation project of Century Plaza on Nanjing East Road, Qinglong's UHPC translucent concrete curtain wall panels withstood rigorous fire testing, maintaining structural integrity at high temperatures of 800°C, and won the AALBORG WHITE Cup UHPC Construction Engineering Innovation Award. This case demonstrates the fire reliability of UHPC materials in settings such as commercial complexes and landmark buildings, providing designers with a solution that combines safety and aesthetics.

Full-Chain Services Empowering Fire Design: Professional Support from Detailed Design to After-Sales Maintenance

Addressing the core needs of real estate developers and architectural design institutes, Qinglong Group provides end-to-end services from fire protection design refinement to installation and construction. During the detailed design phase, BIM technology is used to simulate curtain wall fire protection joints and optimize anchoring systems and sealing processes; in production, automated material distribution and steam curing ensure material homogeneity; and in construction, 3D laser scanning positioning achieves 'zero-error' installation. In addition, supported by a nationwide network of offices, Qinglong has established a 2-hour response after-sales maintenance mechanism, regularly testing and evaluating the fire performance of curtain walls. This integrated 'design-production-construction-maintenance' service model has won strategic recognition from renowned real estate groups such as Poly and China Overseas.

Today, as building safety receives growing attention, UHPC curtain wall panels have become the ideal choice for high-end buildings thanks to their Class A fire performance, excellent mechanical properties, and design freedom. As a professional supplier of UHPC/GRC/GRG/GRP materials, Qinglong Group will continue to uphold its mission of 'Creating Beautiful Architecture,' building architectural spaces that balance safety and aesthetics for customers through technological innovation and full-chain services, helping realize the vision of 'becoming an outstanding world-leading manufacturing enterprise.'
