Analysis of Key Production Process Points and Quality Control Strategies for High-Strength GRC Panels

In the field of contemporary architectural decoration, high-strength GRC panels, with their lightweight yet high-strength properties and flexible shaping capabilities, have become the ideal choice for premium buildings such as grand theaters and commercial complexes. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group leverages its full-chain service capabilities to provide an in-depth analysis of the core essentials of the high-strength GRC panel production process and its quality control logic, offering professional solutions for designers and owners.

Systematic control of the high-strength GRC panel production process is the cornerstone of quality. Its core processes cover three key stages: material mix optimization, forming technology innovation, and curing regime standardization. At the material level, premium GRC panels require carefully selected high-grade cement, alkali-resistant glass fiber, and specialized additives, achieving mechanical performance with a bending strength above 20MPa through precise proportioning. Relying on its provincial-level R&D center, Qinglong Group adopts an automated batching system to ensure that material deviation for each batch is controlled within ±2%, safeguarding product stability at the source. The forming stage combines 3D scanning with customized mold technology to achieve precise replication of complex shapes such as double-curved surfaces and openwork reliefs, with a minimum curvature radius of 300mm, meeting the aesthetic demands of modern architecture.

The quality control system is key to ensuring the performance of high-strength GRC panels. Qinglong Group has established quality control standards covering the entire production process, starting from incoming raw material inspection, using precision equipment such as laser particle size analyzers and universal testing machines to rigorously screen indicators including glass fiber content and cement activity. During production, RFID chip implantation technology enables full life-cycle traceability of components, complemented by BIM technology for digital pre-assembly, ensuring installation accuracy with tolerances of ≤2mm. Addressing durability—a core pain point—the company's self-developed freeze-thaw resistant formula enables products to withstand temperature cycles from -40℃ to 70℃, with salt spray testing exceeding 5,000 hours, far surpassing industry standards.

Full-chain service capabilities determine the project delivery results of high-strength GRC panels. As a national-level high-tech enterprise integrating detailed design, manufacturing, and construction installation, Qinglong Group provides clients with integrated services from scheme optimization to after-sales maintenance. In the Nanjing East Road Century Plaza renovation project, the company optimized the porosity of translucent GRC panels through parametric design and, combined with modular installation technology, reduced the on-site assembly time for 1,200 special-shaped components by 40%. This seamless "design-production-construction" collaboration not only ensured the artistic effect of benchmark projects such as the Dongguan Women and Children's Activity Center, but also achieved precise control of cost and construction schedule.

From material innovation to engineering practice, quality improvement of high-strength GRC panels is inseparable from technical accumulation and standards leadership. Qinglong Group has participated in formulating multiple industry standards, including the "Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC)", driving industry upgrading with 58 patented technologies. In the future, as green building concepts continue to deepen, high-strength GRC panels that combine aesthetic expressiveness with structural safety will shine in more landmark buildings, while Qinglong will continue to uphold its philosophy of "meticulousness and the pursuit of excellence", providing more valuable material solutions for the architectural decoration industry.
