What Is the GRC Production Process: Detailed Guide to GRC Component Manufacturing Workflow and Key Technical Points

The birth of every GRC component is the crystallization of materials science and engineering wisdom. As an industry leader with 28 years of deep expertise in the UHPC/GRC/GRG/GRP materials field, Qinglong Group will take you into the precise world of GRC production technology, revealing the full-process technical code from raw material formulation to finished product installation.

Analysis of the Core Production Processes for GRC Components

The manufacturing process of GRC (Glass Fiber Reinforced Concrete) is a systematic engineering discipline that integrates materials science and engineering technology. Qinglong employs the industry-leading spray-up process, uniformly mixing alkali-resistant glass fibers with special cement-based materials through high-pressure spray guns to form composite structures combining strength and toughness within the molds. This process requires strict control of fiber content (typically 4-5% by volume) and the water-cement ratio, ensuring that the flexural strength of components reaches above 20MPa and meets the highest grade requirements of the Technical Standard for Application of Glass Fiber Reinforced Cement (GRC) in Buildings (JGJ/T423-2018).

Key Control Points in the Standardized Production Process

The production of high-quality GRC components depends on standardized full-process control. Qinglong has established a complete system covering raw material inspection, mold preparation, spray molding, curing and solidification, and quality testing: at the Nanning, Guangxi production base, raw materials must pass 32 indicator tests to ensure the stability of core materials such as cement, quartz sand, and alkali-resistant glass fibers; high-precision CNC-machined molds keep the dimensional errors of components within ±2mm; the proprietary steam curing process enables components to reach 90% of their design strength within 7 days, tripling the efficiency compared with traditional curing.

Technological Innovation Empowers GRC Performance Breakthroughs

As a National High-Tech Enterprise, Qinglong has always driven GRC industry upgrading through technological innovation. By introducing BIM technology and parametric design, it achieves precise prefabrication of complex irregular components with a minimum curvature radius of 300mm; its developed lightweight high-strength formula makes GRC components weigh only 1/4 of traditional stone, greatly reducing building loads; its independently developed surface treatment process can simulate 12 kinds of stone texture effects such as bush-hammered and flamed finishes, demonstrating outstanding decorative expressiveness in projects such as the Dongguan Women and Children's Activity Center.

Full-Chain Services Ensure Project Quality

From detailed design to after-sales maintenance, Qinglong has built a full life-cycle service system for GRC projects. Its technical team holds Grade II professional contracting qualifications for building curtain wall engineering and can provide one-stop solutions ranging from scheme optimization and structural calculation to on-site installation; 3D laser scanning positioning technology ensures installation accuracy with errors of ≤1mm for large projects; the established 24-hour response mechanism and 5-year warranty commitment have provided reliable guarantees for landmark projects such as the Century Plaza on Nanjing East Road.

With 28 years of industry accumulation, Qinglong has developed a GRC production capacity of 600,000 square meters annually, with products exported far to Southeast Asian and Australian markets. From European classical moldings to modern irregular curtain walls, from municipal landscapes to high-end commercial complexes, Qinglong GRC, with its core advantages of “lightweight and high strength, freeform styling, durability and safety,” is becoming the ideal choice for architects to realize their creative visions. Choosing Qinglong means choosing not only quality GRC products, but also trustworthy full-chain technical solutions.
