What Is the GRC Production Process?

In the field of modern architectural decoration, GRC (Glass Fiber Reinforced Concrete) has become the ideal choice for high-end projects such as grand theaters, commercial complexes, and landmark buildings, thanks to its light weight, high strength, and design flexibility. Qinglong Group, with 28 years of industry experience, is deeply engaged in the entire chain of GRC materials, from detailed design and manufacturing to construction, installation, and after-sales maintenance. Today, we take you behind the scenes of the GRC production process and explore how it transforms from raw materials into a carrier of architectural art.

Core Steps of the GRC Production Process: Precision Control from Formulation to Forming

The GRC production process is a perfect combination of materials science and engineering technology, mainly comprising four core steps: raw material preparation, mixing, molding and casting, and curing. As a professional GRC manufacturer, Qinglong has integrated 28 years of technical expertise into every step. For raw materials, high-strength low-alkali cement, alkali-resistant glass fiber, quartz sand, and special additives are carefully selected, and precise proportioning ensures the material's flexural strength exceeds 20MPa, far surpassing industry standards. The mixing stage uses automated equipment to achieve uniform dispersion of glass fiber within the cement matrix, preventing fiber agglomeration that would compromise performance—this is precisely the key to the leading durability of Qinglong GRC products.

The molding process is the soul of GRC's ability to achieve complex shapes. Qinglong adopts a process combining spray-up molding and premix casting, which enables both the efficient production of large-area flat panel components and the precise shaping of special-shaped components such as double-curved surfaces and openwork reliefs, with the minimum radius of curvature controllable within 300mm. Taking the Century Plaza renovation project on Nanjing East Road as an example, its translucent concrete components were realized through custom molds and special casting processes, demonstrating the infinite possibilities of GRC in the art of light and shadow.

Qinglong's GRC Process Advantages: Full-Chain Strength Ensures Quality

As a national high-tech enterprise, Qinglong's innovation in the GRC production process is reflected in three dimensions: first, intelligent production, introducing BIM technology and 3D scanning to achieve seamless conversion from design drawings to production molds, ensuring component dimensional error of ≤2mm; second, a green production philosophy, adopting circulating water systems and dust recovery devices in response to national environmental protection initiatives; third, full lifecycle management, from raw material inspection to pre-delivery load testing, with a comprehensive quality traceability system in place—some projects even have embedded RFID chips to provide data support for later maintenance.

Compared with traditional decorative materials, GRC's production process gives it unique advantages: its weight is only 1/4 that of stone, reducing building loads; its fire resistance rating reaches Class A1, enhancing building safety; and through surface treatment technology, it can simulate various textures such as stone and metal to meet different design style requirements. The "Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC)" (JGJ/T423-2018), which Qinglong participated in formulating, has further solidified these process advantages in the form of industry standards, promoting the standardized development of the entire GRC industry.

Industry Value Behind the Process: From Material Supplier to Solution Partner

The GRC production process is not only a reflection of technology, but also the practice of Qinglong's mission of “creating beautiful architecture”. Addressing real estate developers' concerns about cost control and delivery efficiency, Qinglong has shortened the production cycle of large projects by 30% through standardized molds and modular production. Facing designers' demands for complex shapes, its detailed design team provides full-process services from parametric modeling to on-site installation guidance. For example, in the Dongguan Women and Children's Activity Center project, Qinglong GRC components perfectly presented the streamlined architectural curves, winning the Silver Award of the first GRC Building Engineering Innovation Award.

Today, Qinglong GRC products have been widely applied in landmark projects at home and abroad, from domestic Poly and China Overseas Property projects to projects in Malaysia and Singapore in Southeast Asia. Their stable production process and reliable product quality have been highly recognized by customers. In the future, with the development of UHPC/GRC composite technology, Qinglong will continue to drive the upgrading of architectural decoration materials through process innovation, providing solutions that combine aesthetics and performance for more designers and owners.
