Analysis and Application of Core Technical Indicators of Fire-Resistant GRC Decorative Panels

As an important category among new architectural decorative materials, fire-resistant GRC decorative panels have always drawn industry attention for their technical specifications and application scenarios. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group leverages its full-chain service experience—from material R&D to project implementation—to provide an in-depth analysis of the core value of fire-resistant GRC decorative panels, offering professional solutions for designers and project owners.

I. Analysis of the Core Technical Specifications of Fire-Resistant GRC Decorative Panels

The performance advantages of fire-resistant GRC decorative panels stem from their unique material composition and process standards. First, the fire rating is one of the core specifications: quality products must meet the Class A1 non-combustible standard specified in GB8624, which is attributable to the inorganic nature of the glass fiber reinforced cement substrate; combined with specialized fire-retardant additives, it can effectively block flame spread. Second, in terms of mechanical properties, the flexural strength must be ≥15MPa and the impact strength ≥10kJ/m², ensuring the panels are not prone to cracking or deformation over long-term building use. In addition, weather resistance indicators include ≥100 freeze-thaw cycles and alkali resistance compliant with the JC/T940 standard, guaranteeing stability under different climatic conditions. Through technical breakthroughs at its provincial-level R&D center, Qinglong Group has integrated these specifications into the entire production process; its products have passed the Guangdong Province Scientific and Technological Achievement Appraisal, with multiple patented technologies enhancing the comprehensive performance of fire-resistant GRC.

II. Innovative Applications of Fire-Resistant GRC in Building Scenarios

The application scenarios of fire-resistant GRC decorative panels are expanding from traditional exterior walls to diversified fields. In high-end public buildings, such as exterior wall cladding panels for grand theaters and convention centers, their lightweight properties (weighing only 1/4 of natural stone) reduce building loads, while customized shaping capabilities meet architects' demands for complex designs such as curved surfaces and openwork patterns. In commercial complex projects, fire-resistant GRC is used in combination with UHPC to form integrated curtain wall systems that combine fire protection, thermal insulation, and decorative functions, with typical cases including projects in partnership with property groups such as Poly and Vanke. In addition, in municipal engineering such as subways and utility tunnels, their fire resistance and durability advantages are remarkable; Qinglong's overseas projects, such as its application at a Malaysia airport, have demonstrated the product's reliability in extreme environments.

III. Key Considerations for Selecting a Fire-Resistant GRC Supplier

For real estate developers and design institutes, selecting a fire-resistant GRC supplier requires attention to three dimensions: In terms of technical strength, examine whether the manufacturer has participated in developing industry standards—for example, Qinglong, as a contributing unit to the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), possesses technical authority. In terms of production capacity, Qinglong's Guangxi base, with an annual capacity of 600,000 square meters, can guarantee the delivery of large-scale projects. Full-process services cover detailed design, BIM technology application, installation guidance, and after-sales maintenance—for example, in the Century Plaza renovation project on Nanjing East Road, Qinglong achieved a seamless integration of light-transmitting concrete and fire-resistant GRC through parametric design.

Technological innovation and application expansion of fire-resistant GRC decorative panels are reshaping the selection logic for architectural decorative materials. With the mission of "Creating Aesthetic Architecture," Qinglong Group will continue to drive the value realization of fire-resistant GRC in more scenarios through material R&D and engineering practice, providing the industry with safe, durable, and beautiful decorative solutions.
