What Are the Core Criteria for Evaluating GRC Manufacturer Technical Strength and Key Assessment Directions

In the field of architectural decorative materials, technical strength is the core competitiveness that enables GRC manufacturers to establish themselves in the market, and it is also a key consideration for designers and owners when selecting partners. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group, grounded in full-chain service experience, provides an in-depth analysis of the evaluation criteria and key directions for assessing the technical strength of GRC manufacturers, offering professional reference for the industry.

1. Material R&D and Performance Control: The Fundamental Guarantee of GRC Quality

Technical strength is first reflected in the scientific formulation of materials and the stability of their performance. High-quality GRC manufacturers must master the compatibility technology between glass fiber and cement matrix, ensuring products achieve a flexural strength of ≥15MPa and meet impact resistance standards through measures such as fiber content optimization (typically controlled at 3%-5%) and admixture improvement, while also possessing excellent weather resistance and fire rating (no lower than Class A). Relying on its provincial-level R&D center, Qinglong Group has established a full-process quality control system from raw material screening to finished product testing. Its GRC products have undergone 2,000 freeze-thaw cycle tests without damage, with performance indicators far exceeding industry standards—a direct reflection of its technical accumulation.

2. Deepened Design and Complex Shape Realization Capability: Core Support for Bringing Creativity to Life

Modern architecture imposes increasingly complex shape requirements on GRC components; hyperbolic surfaces, hollowed-out reliefs, and oversized irregular structures have become the norm. When conducting assessments, focus on the manufacturer's design deepening capabilities, including parametric design (e.g., Rhino+Grasshopper applications), BIM technology integration, and 3D scanning precision. Qinglong Group participated in formulating the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018). In projects such as the Dongguan Women and Children's Activity Center, it successfully achieved seamless splicing of hyperbolic components with a minimum radius of curvature of 300mm, demonstrating its precise transformation capability from drawings to finished products.

3. Production Processes and Intelligent Manufacturing Level: The Efficiency Key to Large-Scale Delivery

The ability to balance standardized production with flexible customization is an important dimension of technical strength. Assessment directions include mold technology (e.g., the adaptability of silicone molds and steel molds), automated forming equipment (e.g., fiber dispersion uniformity of spray-up machines), and production capacity. Qinglong's Guangxi production base has an annual capacity of 600,000 square meters and adopts an intelligent warehouse management system and RFID chip tracing technology to ensure full-process controllability from production to installation. It efficiently delivered light-transmitting concrete components for the Nanjing Road Century Plaza renovation project, confirming its technical advantage in large-scale customization.

4. Full-Chain Service and Engineering Case Verification: The Value Accumulation of Practical Experience

Technical strength ultimately needs to be verified through the results of project implementation. During assessment, attention should be paid to whether the manufacturer possesses full-chain service capabilities covering 'deepened design - production and manufacturing - construction and installation - after-sales maintenance,' as well as its application cases in high-end projects. As a national high-tech enterprise, Qinglong Group has completed more than 1,000 major engineering projects, from landmark building facades to irregular components for themed parks. Its long-term cooperation with renowned real estate groups such as Poly and China Overseas not only reflects technical reliability but also highlights its comprehensive service capabilities in complex projects.

Choosing a GRC manufacturer is essentially choosing a technology partner. From material R&D to project implementation, Qinglong Group has built a technical moat with 28 years of professional experience. Its hardcore strength—participating in formulating multiple industry standards and holding 58 patents—is the best interpretation of its mission of 'creating aesthetically beautiful architecture.' For designers and owners pursuing quality and innovation, assessing technical strength is not only a necessary step to avoid risks, but also a key decision to achieve a win-win between architectural aesthetics and engineering value.
