What Is the Production Process of GRC? A Detailed Look at GRC Material Manufacturing Process and Key Technologies

In the field of contemporary architectural decoration, Glass Fiber Reinforced Concrete (GRC) has become a key material for shaping architectural aesthetics and functionality, thanks to its lightweight, high-strength, and flexible-forming properties. 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 transform the craft value of GRC materials into unlimited possibilities of architectural art.

The Core Craftsmanship of GRC Materials: Precision Control from Formulation to Forming

The core of GRC production lies in the synergy between material proportions and forming technology. Qinglong uses customized cement-based formulations, mixing alkali-resistant glass fibers (content typically controlled at 4-6%) with special cement, quartz sand, and additives in precise proportions, and ensures slurry uniformity through automated mixing systems. This step directly determines the flexural strength (up to over 20MPa) and durability of GRC components, and is the key factor that distinguishes them from ordinary cement products.

Mold Design and Forming: A Bridge to Realizing Architectural Creativity

Mold craftsmanship is the foundation of GRC's shaping capabilities. Backed by its detailed design team, Qinglong employs BIM technology and parametric design software (such as Rhino and Grasshopper) to transform architects' complex creative concepts into producible mold solutions. For special shapes such as double-curved surfaces and openwork reliefs, fiberglass molds or 3D printing rapid prototyping technology are adopted to ensure component precision with an error of ≤2mm. In the production stage, a process combining spray-up forming and premix casting ensures both the uniform distribution of glass fibers and the fine replication of complex surface textures.

Curing and Quality Control: Key Steps to Ensure Long-Term Performance

The curing process directly affects the strength development and stability of GRC components. Qinglong uses a constant temperature and humidity curing system, accelerating the hydration reaction through 7 days of steam curing (temperature controlled at 60-80℃) to increase the early strength of components by more than 30%. Meanwhile, RFID chip traceability technology is introduced to record data throughout the entire process from raw materials to finished products. Combined with flexural and freeze-thaw resistance testing by third-party testing institutions, this ensures that every batch of products complies with the Technical Standard for Building Applications of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018).

Qinglong GRC's Full-Chain Advantages: Integrated Services from Design to Maintenance

As a National High-Tech Enterprise, Qinglong deeply integrates production craftsmanship with engineering services. In the Dongguan Women and Children's Activity Center project, optimizing the division of GRC curtain wall panels through detailed design increased installation efficiency by 40%; the Nanjing Road Century Plaza renovation project innovatively combined light-transmitting materials with GRC to achieve artistic light-and-shadow effects on the building skin. From technical consulting at the early project stage, to schedule control during production, and to a 5-year maintenance commitment after installation, Qinglong delivers value beyond the materials themselves with its full-chain capabilities of "Design-Production-Construction-Maintenance."

From European classical lines to the irregular skins of modern architecture, the craft evolution of GRC materials has always served architectural aesthetics and functional needs. With 28 years of technical accumulation, Qinglong Group deeply combines material performance with engineering practice, not only promoting the establishment of GRC industry standards, but also, under the mission of "Creating Aesthetic Architecture," enabling this material to radiate unique value in real estate, municipal projects, cultural venues, and other fields. Choosing Qinglong GRC means not only choosing a material, but also choosing a full-process solution from concept to realization.
