Does GRC Meet Fire Performance Standards?

In the field of building safety, fire resistance is one of the key indicators for measuring material quality. As a technology-focused player in the glass fibre reinforced concrete (GRC) industry, Qinglong Group, with 28 years of full-chain experience, provides the market with GRC solutions that combine artistic expression with safety assurance. This article analyzes the core advantages of GRC fire resistance from three dimensions—material properties, industry standards, and engineering practice—to provide professional reference for designers and owners.

The fire resistance of GRC materials stems from their unique composite structure. The scientific ratio of glass fibre to cement matrix gives GRC products inherent non-combustibility, with combustion performance meeting the Class A standard specified in GB8624. In high-temperature environments, GRC components can maintain structural integrity, effectively delaying the spread of fire and buying valuable time for evacuation. GRC panels produced by Qinglong have been verified by national-level testing institutions, with a fire resistance limit of over 3 hours, fully meeting the fire protection design requirements of large public buildings.

The formulation and enforcement of industry standards provide an important guarantee for GRC fire resistance. As a major contributing unit of the Technical Standard for Application of Glass Fibre Reinforced Cement (GRC) in Buildings (JGJ/T423-2018), Qinglong was deeply involved in setting the fire resistance indicators for GRC. The standard clearly specifies key parameters such as combustion performance, smoke toxicity, and fire resistance limit of GRC products, and requires manufacturers to establish sound quality control systems. Relying on its provincial engineering technology center, Qinglong has incorporated fire resistance testing into the factory inspection process for every batch of products, ensuring that delivered projects meet material performance standards.

In actual engineering applications, the fire resistance advantages of GRC have been verified by numerous benchmark projects. From the shaped exterior walls of the Dongguan Women and Children's Activity Center to the translucent concrete components of Century Plaza on Nanjing East Road, Qinglong GRC products have always prioritized fire safety while meeting complex design requirements. Especially in densely populated venues such as theatres and convention centers, the combined application of GRC with materials such as UHPC and GRG forms a multi-layered fire barrier system. These project cases not only demonstrate Qinglong's strength in material R&D, but also reflect the company's commitment to building safety.

For designers and owners, choosing GRC materials that meet fire resistance standards is not only a necessary measure to satisfy code requirements, but also a strategic choice to safeguard the safety of a building's entire life cycle. As a national high-tech enterprise, Qinglong has always upheld the mission of "creating aesthetically pleasing architecture," continuously improving the fire resistance and overall quality of GRC through technological innovation. In the future of architectural decoration, GRC, with its multiple advantages such as fire resistance, light weight, and flexible styling, will surely become the material of choice for more high-end projects.
