Core Technical Indicators of Fire-Resistant GRC Decorative Panels Explained: Key Performance Parameters and Quality Control Points

In the field of modern architectural decoration, material performance and quality are the core factors determining a project's safety and aesthetics. As a new building material combining functionality and artistry, fireproof GRC decorative panels' technical specifications directly relate to a building's safety rating and service life. As an industry participant with 28 years of deep involvement in the UHPC/GRC/GRG/GRP materials field, Qinglong Group will analyze the technical core of fireproof GRC decorative panels from two aspects—core performance parameters and quality control systems—providing professional reference for designers and owners.

I. Analysis of Key Performance Parameters of Fireproof GRC Decorative Panels

The technical advantages of fireproof GRC decorative panels are first reflected in the balance of their composite performance. As a subcategory of glass fibre reinforced concrete (GRC), their core parameters must meet the dual requirements of building fire protection and structural safety. In terms of fire performance, high-quality fireproof GRC decorative panels should meet the Class A non-combustibility standard specified in GB8624, with a fire resistance limit of 1-4 hours according to building design requirements—an indicator achieved by adjusting the glass fibre content (typically 4-6%) and the cement-based material mix ratio. Meanwhile, their physical and mechanical properties must meet flexural strength ≥12MPa and compressive strength ≥60MPa, ensuring resistance to wind loads and temperature deformation in high-rise building facade applications.

Durability indicators are equally critical. Fireproof GRC decorative panels should pass 200 freeze-thaw cycle tests with no obvious damage, and their impermeability rating should reach P6 or above to adapt to usage environments in different climate zones. Notably, through 28 years of engineering practice, Qinglong Group has found that adopting an autoclaved curing process can keep product moisture content below 8%, effectively avoiding later cracking risks. This process advantage has been verified in projects such as the Nanjing East Road Century Plaza renovation.

II. The Construction Logic of a Full-Chain Quality Control System

The quality stability of fireproof GRC decorative panels depends on full-process control from raw materials to installation. On the materials side, Qinglong Group has established a strict incoming inspection system: glass fibre must comply with the ASTM C1666 standard, and cement-based materials use 42.5R grade Portland cement with selected quartz sand to ensure stable substrate performance. The production process introduces BIM technology and automated forming equipment to control component dimensional precision within ±2mm—a precision level that is particularly critical in irregular-shaped projects such as the Dongguan Women and Children's Activity Center.

Installation workmanship directly affects the safety performance of fireproof GRC decorative panels. Qinglong's "3D laser scanning + modular installation" technology achieves on-site positioning errors of ≤3mm. Combined with stainless steel embedded parts and flexible connection joint design, it effectively resolves hidden dangers caused by building settlement and thermal stress. In addition, every batch of products is embedded with an RFID chip to achieve full life-cycle traceability—this quality control model has become an industry benchmark.

III. Application Value and Industry Trends of Fireproof GRC Decorative Panels

Against the backdrop of increasingly stringent green building and fire safety requirements, fireproof GRC decorative panels are becoming the preferred material for high-end buildings. Compared with traditional stone curtain walls, they are over 60% lighter, reducing building structural loads; compared with metal sheets, they offer superior fire performance and greater design freedom. With an annual production capacity of 600,000 square meters and a service network covering the whole country, Qinglong Group has successfully applied fireproof GRC decorative panels in commercial complexes, cultural venues and other scenarios, and its overseas market has expanded to Southeast Asia and the Middle East.

With the implementation of standards such as the Technical Standard for Application of Glass Fibre Reinforced Cement (GRC) in Buildings (JGJ/T423-2018), the technical standards for fireproof GRC decorative panels will become more complete. As a participant in industry standard setting, Qinglong Group always adheres to the values of "honesty, striving, trust and collaboration," promoting the in-depth application of fireproof GRC decorative panels in building safety and aesthetic expression through technological innovation and quality control, continuously empowering the mission of "creating aesthetic architecture."
