How Is Quality Stability of Batch-Produced GRC Products Ensured?

In the field of architectural decorative 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, the quality stability of mass-produced GRC products has always been a focal point of industry attention. As Qinglong Group, with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, we deeply understand that quality is the lifeline of an enterprise. Through technological innovation, standardized management, and strict quality control, we provide customers with stable and reliable GRC products.

### I. Material Source Control: Laying the Cornerstone of Stable GRC Quality

The quality stability of GRC products begins with the strict selection of raw materials. Qinglong Group has established a comprehensive supply chain management system, implementing an 'access system' for core raw materials such as glass fiber, cement, and admixtures, and building long-term partnerships with renowned domestic and international suppliers. For example, high alkali-resistant glass fiber is selected to ensure that it maintains excellent mechanical properties in the alkaline environment of cement; special cement is adopted to optimize the hydration reaction process, improving product strength and durability. Meanwhile, advanced material testing equipment is used to conduct composition analysis and performance testing on every batch of raw materials, preventing substandard materials from entering the production process.

### II. Intelligent Production: Achieving Precise Control of Mass GRC Manufacturing

Traditional production modes are easily affected by manual operations, resulting in quality fluctuations in GRC products. Qinglong Group has introduced intelligent production equipment and built industry-leading automated production lines. From batching and mixing to molding and curing, the entire process is controlled by computer programs, achieving raw material ratio precision of ±1% and improving mixing uniformity by more than 30%. In addition, through BIM technology and parametric design software (such as Rhino and Grasshopper), complex shapes are converted into standardized production parameters, ensuring that the dimensional error of each GRC component is controlled within ±2mm. Intelligent production not only improves production efficiency but also fundamentally guarantees the consistency of mass-produced products.

### III. Full-Process Quality Control System: Building a 'Firewall' for GRC Quality

Qinglong Group follows the quality policy of 'meticulousness and constant pursuit of excellence' and has established a quality control system covering the entire process of design, production, and construction. In the design stage, finite element analysis software is used to simulate the structural loading of GRC components and optimize reinforcement schemes; during production, the 'three-inspection system' (self-inspection, mutual inspection, and special inspection) is implemented, with focused monitoring of key links such as molding processes and curing conditions, ensuring product flexural strength ≥20MPa and water absorption ≤8%; before leaving the factory, each batch of products undergoes more than 10 index inspections including load testing and weather resistance testing, accompanied by complete quality traceability reports. In addition, the company participated in formulating the 'Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC)' (JGJ/T423-2018), leading quality improvement through industry standards.

### IV. Technological R&D and Experience Accumulation: Continuously Improving GRC Quality Stability

As a National High-Tech Enterprise and a provincial-level R&D center, Qinglong Group has been deeply engaged in GRC technological innovation for 28 years, accumulating 58 patents, with many products passing scientific and technological achievement appraisals. Addressing common problems in mass production, such as component cracking and surface color variation, the R&D team has formed a mature set of solutions through improved formulations and optimized curing processes. For example, the 'gradient curing method' is adopted to effectively reduce cracking caused by temperature stress; automated spraying equipment is used to ensure uniform and consistent surface texture. Meanwhile, drawing on practical experience from more than a thousand projects, a GRC quality issue database has been established to enable early warning and rapid response to problems.

### V. Full Life-Cycle Service: Ensuring Long-Term Stability of GRC Project Quality

Qinglong Group provides 'one-stop' services ranging from detailed design and manufacturing to construction installation and after-sales maintenance. In the construction phase, 3D laser scanning positioning technology is adopted to ensure the installation precision of GRC components; a regular inspection system has been established to conduct durability assessments and maintenance for delivered projects. For example, the GRC exterior wall panels supplied for a commercial complex project have withstood 5 years of wind and rain while still maintaining good structural performance and appearance quality, winning high recognition from the customer. This full life-cycle service model not only ensures the stability of GRC products during use but also demonstrates Qinglong's responsibility and commitment as an industry leader.

The quality stability of mass-produced GRC products is a reflection of a company's comprehensive strength. Qinglong Group has built a scientific and comprehensive quality assurance system with material control as the foundation, intelligent production as the means, full-process quality control as the guarantee, and technological R&D as the driving force. In the future, Qinglong will continue to focus on the development of UHPC/GRC/GRG/GRP materials, upholding the mission of 'creating beautiful architecture,' providing customers with better and more stable products and services, and striving to become an outstanding world-leading UHPC/GRC/GRG/GRP manufacturing enterprise.
