How Do Production Processes Differ Among GRC Manufacturers — An Analysis of Technical Routes, Raw Material Selection, and Quality Control Differences

In the field of architectural decoration materials, GRC (Glass Fiber Reinforced Concrete) is widely used in high-end projects such as grand theaters, commercial complexes, and landmark buildings, thanks to its advantages of light weight, high strength, and flexible shaping. However, production processes differ significantly among GRC manufacturers, and these differences directly affect product quality, engineering results, and project costs. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group will analyze the process differences among GRC manufacturers from three dimensions—technical route, raw material selection, and quality control—to provide professional reference for designers and owners.

I. Technical Route: Iteration from Traditional Casting to Intelligent Production

Differences in technical routes among GRC manufacturers are reflected in the molding process and the advancement of production equipment. Traditional manufacturers mostly use manual spraying or mold casting, relying on manual operations, resulting in low production efficiency and poor product consistency, making it difficult to meet complex shaping requirements. In contrast, industry-leading GRC manufacturers such as Qinglong have introduced automated production lines and digital design tools to achieve full-process control from parametric modeling to modular production. For example, the 3D scanning and BIM technology adopted by Qinglong can accurately convert complex designs such as double-curved surfaces and openwork reliefs into production data; combined with robotic spray molding, the minimum curvature radius is controlled within 300mm and surface precision reaches ±1mm, significantly enhancing the ability to realize special-shaped components.

II. Raw Material Selection: The 'Golden Ratio' of Fiber and Cement Determines the Performance Ceiling

Raw materials are the core guarantee of GRC product quality, and different manufacturers' material selection standards directly affect product strength and durability. High-quality GRC manufacturers strictly screen glass fiber and cement types: glass fiber must be alkali-resistant, with length and diameter meeting industry standards (such as JC/T940-2022) to ensure flexural strength above 20MPa; for cement, low-alkali sulphoaluminate cement is preferred to reduce the risk of alkali-aggregate reaction. As a participant in drafting the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), Qinglong has established a raw material traceability system, controlling fiber content (typically 4-5%) and cement grade at the source to ensure products maintain stable performance in environments from -40℃ to 70℃. In contrast, some manufacturers use ordinary glass fiber or low-grade cement to reduce costs, resulting in products that are prone to cracking and lack durability, creating potential safety hazards.

III. Quality Control: A Full-Chain Quality Control System Ensures Engineering Reliability

Quality control is a key link in GRC production, and standardized quality control processes can effectively avoid problems such as component cracking and falling off. Mature GRC manufacturers such as Qinglong have built a full-chain quality control system covering 'design-production-installation': at the design stage, anchoring schemes are optimized through structural force simulation; during production, steam curing is combined with natural curing, with demolding strength controlled at ≥15MPa; before leaving the factory, flexural and impact resistance tests are conducted, and RFID chips are embedded to achieve quality traceability. During installation, Qinglong uses 3D laser scanning positioning technology to ensure that jointing errors of components are ≤2mm, and works with customized metal connectors to enhance overall safety. In contrast, some small manufacturers lack complete testing equipment and quality control processes, relying only on manual visual inspection, making it difficult to guarantee stable product quality.
