How Do Production Processes Differ Among GRC Manufacturers — An In-Depth Analysis of Each Manufacturer's Process Characteristics and Differences

In the field of architectural decoration materials, craftsmanship is the foundation of quality and the soul of innovation. Differences in production processes among GRC manufacturers not only determine product performance, but also directly affect the aesthetic presentation, safety, and durability of construction projects. As an industry veteran with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group will provide an in-depth analysis of each manufacturer's process characteristics and differences from core dimensions such as material formulation, molding processes, and quality control, offering a professional selection reference for designers and project owners.

GRC Manufacturer Process Differences: Quality Foundations from the Material Source

Material formulation is the core competitiveness of GRC processes, and different manufacturers show significant differences in the selection and proportioning of cement, glass fiber, and additives. Premium manufacturers such as Qinglong Group insist on using high-grade sulfoaluminate cement and alkali-resistant glass fiber (content ≥5%), achieving industry-leading standards of flexural strength ≥20MPa and impact resistance ≥10kJ/m² through precise formulation; whereas some small and medium-sized manufacturers, in order to control costs, may use ordinary Portland cement or reduce fiber content, resulting in products that are prone to cracking and lack durability. In addition, Qinglong's proprietary mineral admixture formula keeps the product's dry density at 1.8-2.0g/cm³, reducing weight by 15% compared with traditional processes, ensuring safety while reducing structural load.

Molding Process Comparison: Customization Capability Determines Design Realization

In molding processes, the differences in technical approaches among GRC manufacturers are directly reflected in their ability to realize complex shapes. Qinglong Group adopts a combined process of “automated spraying + precision molds”, achieving uniform fiber distribution through a robotic spraying system, combined with CNC-machined high-precision molds (tolerance ≤0.5mm), perfectly rendering complex structures such as double-curved surfaces and openwork reliefs, with a minimum curvature radius of 300mm; whereas some manufacturers still rely on manual plastering, which not only results in low production efficiency but is also prone to problems such as uneven fiber distribution and poor surface flatness. Taking the translucent concrete project at Century Plaza on Nanjing East Road as an example, Qinglong kept the deviation of more than 2,000 specially-shaped UHPC components within 2mm through parametric design and prefabricated assembly processes, winning an industry innovation award—strong proof of advanced molding processes.

Full-Process Quality Control: A Closed Quality Loop from Laboratory to Construction Site

The ultimate manifestation of process differences lies in the maturity of the quality control system. Qinglong Group has established full-chain quality control standards covering “material testing - production monitoring - installation acceptance - after-sales maintenance”: each batch of raw materials must pass more than 30 index tests (such as alkali-resistance testing of alkali-resistant glass fiber and verification of cement strength grades); the production process uses BIM technology for full traceability, with 3-level quality inspections set at key procedures; and the installation stage employs 3D laser scanning positioning to ensure “zero-error” joints. By contrast, some manufacturers lack systematic quality control measures and rely solely on final inspections, making it difficult to guarantee product consistency. As a participating unit in drafting the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC), Qinglong's quality control standards have become an industry benchmark.

Choosing a GRC manufacturer is essentially choosing the technical expertise and sense of responsibility behind the craftsmanship. With 28 years of dedication to the UHPC/GRC/GRG/GRP fields, Qinglong Group, backed by its strength as a National High-Tech Enterprise and a Specialized and Sophisticated Enterprise, integrates the commitment of “meticulousness and the constant pursuit of excellence” into every process. Whether for real estate curtain walls, municipal landmarks, or overseas projects, Qinglong consistently leverages its full-chain service capabilities to provide customers with expert-level solutions from detailed design to after-sales maintenance, allowing architectural beauty to radiate lasting value through craftsmanship precision.
