Analysis of Key Points in High-Strength GRC Panel Production Process: Core Technologies and Quality Control Essentials

In the field of contemporary architectural decoration, high-strength GRC panels have become the ideal choice for high-end buildings such as grand theaters and commercial complexes, thanks to their lightweight, high-strength, and flexible-forming characteristics. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group has always upheld the mission of "Creating Beautiful Architecture," continuously breaking through in the production processes of high-strength GRC panels, deeply integrating technological innovation with quality control, and providing full-chain solutions for designers and owners worldwide.

Core Technologies in High-Strength GRC Panel Production: Precise Control from Materials to Forming

The exceptional performance of high-strength GRC panels stems from the ultimate pursuit of material proportions and production processes. As a national high-tech enterprise, Qinglong Group adopts a scientific ratio of high-grade cement and alkali-resistant glass fibers in its material formulations, using patented technologies (such as the invention patent "A Lightweight High-Strength GRC Composite Material") to raise the flexural strength of panels to over 20MPa, far exceeding industry standards. During production, Qinglong introduced an automated material distribution system and a three-dimensional vibration process to ensure uniform distribution of glass fibers in the matrix, effectively preventing air bubbles and cracks. This technical advantage enabled its products to achieve precise realization of complex curved shapes in projects such as the Century Plaza renovation on Nanjing East Road.

Quality Control Essentials: An Industry Benchmark for Whole-Process Standardized Management

Qinglong Group has established a full-chain quality control system covering detailed design, manufacturing, and construction installation. In the production stage, each batch of high-strength GRC panels undergoes dual aging treatment of 72 hours of steam curing and 28 days of natural curing, together with flexural and impact resistance testing using German-imported testing equipment, maintaining a pass rate of over 99%. Addressing customers' concerns about durability, Qinglong verifies product stability in extreme environments from -40℃ to 70℃ through accelerated aging tests, ensuring a service life of more than 50 years in key projects such as airports and landmark buildings.

Customized Production and Full-Cycle Services: Meeting the Differentiated Needs of High-End Projects

In response to designers' demands for complex shapes, Qinglong leverages the R&D capabilities of its provincial-level engineering technology center, employing BIM technology and parametric design software to achieve seamless connection from drawing detailing to mold customization. For example, in the Dongguan Women and Children's Activity Center project, its team used 3D scanning technology to accurately reproduce hyperbolic curved components and, combined with modular installation techniques, kept on-site assembly errors within 2mm. In addition, Qinglong's after-sales maintenance services, including regular inspections and structural reinforcement solutions, provide long-term assurance for overseas projects (such as a commercial complex in Malaysia).

As the vice chairman unit of the China GRC Association and a member of the International GRC Association, Qinglong Group participated in formulating the "Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC)" (JGJ/T423-2018), promoting industry standardization with the principle of "meticulousness and the pursuit of excellence." Looking ahead, Qinglong will continue to focus on the innovative R&D of UHPC/GRC/GRG/GRP materials, striving to become a world-leading manufacturer of architectural decoration materials and contributing Chinese wisdom to global architectural aesthetics.
