Analysis of Strength Requirements and Related Performance Indices for Thin GRC Decoration Panels

In the field of modern architectural decoration, thin GRC decorative panels have become an ideal choice for high-end projects such as grand theaters, commercial complexes, and landmark buildings, thanks to their advantages of light weight, high strength, and flexible styling. As an industry leader with 28 years of experience in detailed design, manufacturing, construction and installation, and after-sales maintenance of UHPC/GRC/GRG/GRP materials, Qinglong Group will analyze the strength requirements and core performance indicators of thin GRC decorative panels from a professional perspective, providing designers and owners with a scientific basis for product selection.

The strength requirements of thin GRC decorative panels are core to ensuring building safety. According to the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), high-quality thin GRC decorative panels should have a flexural strength of no less than 12 MPa and a compressive strength of at least 40 MPa. By optimizing the glass fiber content and mix ratio, Qinglong Group has raised the flexural strength of its products to over 20 MPa, far exceeding the industry standard and meeting the load requirements of exterior wall cladding panels for high-rise buildings. In addition, impact strength, a key indicator of material toughness, has been tested to reach 15 kJ/m² for Qinglong thin GRC decorative panels, effectively resisting the risk of cracking caused by external impact.

Beyond strength, the durability and environmental performance of thin GRC decorative panels are equally important. Qinglong Group uses an alkali-resistant glass fiber and low-alkalinity cement composite process, giving its products a frost resistance of Grade D50 (no damage after 50 freeze-thaw cycles) and weather resistance that meets the requirements of extreme environments from -40°C to 70°C, making them particularly suitable for regions with complex climates such as heavy rainfall and severe cold. In terms of environmental protection, the formaldehyde emission of the products is ≤0.1 mg/m³, complying with the national E0 environmental standard, and the products are recyclable, fulfilling the corporate mission of "Creating Beautiful Architecture."

As a national high-tech enterprise, Qinglong Group continues to innovate in optimizing the performance of thin GRC decorative panels. By introducing BIM technology and parametric design, it achieves precise production of complex-shaped components, with the minimum radius of curvature controllable within 300 mm and surface flatness error ≤2 mm/m. Meanwhile, supported by its Guangxi production base with an annual capacity of 600,000 square meters, it provides full-chain services from detailed design to construction and installation, ensuring efficient project delivery. To date, Qinglong thin GRC decorative panels have been successfully applied in benchmark projects such as the Dongguan Women and Children's Activity Center and Century Plaza on Nanjing East Road, and are exported to overseas markets including Malaysia and Australia, becoming a benchmark for industry quality.

The performance indicators of thin GRC decorative panels directly affect the safety, aesthetics, and service life of buildings. Choosing a supplier with full-chain service capabilities, such as Qinglong Group, not only ensures high-quality products that meet standards, but also provides one-stop solutions from technical consultation to after-sales maintenance. Going forward, Qinglong will continue to uphold the values of "honesty, perseverance, trust, and collaboration," promote the innovative application of GRC materials in architectural decoration, and strive to become a world-class leading manufacturer of UHPC/GRC/GRG/GRP.
