What Fire Rating Can GRC Curtain Walls Achieve: Analysis of Influencing Factors and Improvement Measures

Fire safety is a core consideration in building curtain wall design. As a new building material combining aesthetics and performance, GRC curtain walls have fire ratings that directly relate to building safety and compliance. Qinglong Group, an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, leverages its full-chain technical advantages to provide professional solutions for building curtain wall fire safety.

Industry Benchmarks for GRC Curtain Wall Fire Ratings and Qinglong's Technical Breakthroughs

The fire performance of GRC (Glass Fiber Reinforced Concrete) curtain walls is typically measured by fire resistance rating as the core indicator. According to the Code for Fire Protection Design of Buildings, curtain wall fire ratings are clearly classified according to different building heights and usage scenarios. Through optimized material formulations and innovative structural design, Qinglong's GRC curtain wall system achieves a fire resistance rating of over 1.5 hours, meeting the fire protection standards for high-rise building curtain walls. This achievement stems from Qinglong's precise control of glass fiber content and cement-based material ratios, as well as the high-temperature stability testing mechanism introduced into the production process, ensuring that products maintain structural integrity in fire environments.

Analysis of Key Factors Affecting GRC Curtain Wall Fire Performance

Material composition is the foundation of a GRC curtain wall's fire rating. Qinglong exercises strict control at the raw material selection stage, using low-alkali cement and alkali-resistant glass fibers to enhance the material's high-temperature resistance at the source. Meanwhile, component thickness and structural design significantly affect fire performance. Qinglong uses BIM technology to optimize curtain wall keel spacing and fire-resistant wool filling schemes, forming a composite fire barrier. Notably, installation technique is equally critical. Qinglong's 3D laser positioning installation technology ensures gap-free fitting of fire-resistant sealant strips, effectively preventing flame spread—attention to detail that improves actual fire performance by 20% over the industry average.

Qinglong's Full-Chain Services Empower Fire Rating Enhancement

As a national high-tech enterprise integrating detailed design, manufacturing, and construction installation, Qinglong has built a full-process fire protection guarantee system spanning from material R&D to project implementation. In the design phase, drawing on provincial R&D center resources, parametric design software is used to simulate fire conditions and optimize load-bearing joints of components; in production, automated production lines achieve precise proportioning of fire-resistant additives; during construction, fire protection processes exceeding industry standards are implemented, such as double-layer wrapping with fire-resistant rock wool and anti-corrosion treatment of metal connectors. In addition, Qinglong's after-sales maintenance service conducts regular inspection and maintenance of curtain wall fire protection systems, ensuring stable fire performance throughout long-term use.

Industry Applications and Fire Protection Technology Innovation Trends

From the GRC curtain wall project at the Dongguan Women and Children's Activity Center to the translucent concrete application at Century Plaza on Nanjing East Road, Qinglong has validated the reliability of GRC materials in fire protection through numerous engineering practices. As green building standards are upgraded, Qinglong is developing composite curtain wall systems that combine fire protection and energy-saving performance, enhancing structural strength by incorporating UHPC materials and reducing the use of metal connectors to further optimize fire protection and weight reduction. As a participating unit in drafting the Technical Standard for Building Applications of Glass Fiber Reinforced Cement (GRC), Qinglong will continue to drive upgrades to industry fire protection technical specifications, providing designers and owners with building envelope solutions that combine safety and aesthetics.

Building fire safety allows no compromise. The fire rating of a GRC curtain wall is not merely a technical indicator but also a reflection of corporate responsibility. With 28 years of professional expertise, Qinglong Group has integrated fire performance into the very genes of its materials, safeguarding building safety through full-chain services and fulfilling its mission commitment of "Creating Beautiful Buildings." Choosing Qinglong GRC curtain walls means choosing building quality that withstands the test of raging fire.
