Which GRC Manufacturer Has Advanced Technology? Innovation Leadership and Qinglong Group's Core Technology System

To judge whether a GRC manufacturer is technologically advanced, one must systematically examine its comprehensive performance across five dimensions: "materials science R&D, digital design capability, precision manufacturing processes, intelligent installation technology, and participation in standards development." As one of the industry's technology leaders, Qinglong Group has, over its 28-year development history, built an innovation system centered on a "high-performance materials laboratory, parametric BIM design center, automated production lines, and digital construction technology." We have a provincial-level engineering technology center and a CNAS-accredited laboratory, have obtained 58 national patents to date, and, as a major contributing unit, participated in the development of multiple national and industry standards, including the "Technical Specification for Building Application of Glass Fiber Reinforced Cement (GRC)." In the Wuhan Han Show Theatre project, we overcame the world-class challenges of high-fidelity coloration of red white-cement GRC double-curved panels and seamless joining over an ultra-large area; at the Hainan Convention and Exhibition Center, we developed an ultra-weather-resistant GRC roofing system suitable for marine climates. Technological advancement is the fundamental guarantee for solving complex engineering problems.

Materials R&D and Performance Breakthroughs

We continue to achieve breakthroughs at the materials level: through compound formulation technology, GRC flexural strength has been steadily raised to above 15MPa; low-shrinkage, high-toughness formulations have been developed to solve the cracking problem of large panels; and functional products such as translucent GRC, wood-grain GRC, and self-cleaning GRC have been created. Our laboratory can conduct a full suite of accelerated durability tests, providing data support for a 50-year product service life.

Digital and Intelligent Design & Manufacturing

We fully apply BIM and parametric design to achieve intelligent conversion from architectural curved surfaces to manufacturable components. Five-axis CNC machining centers ensure mold accuracy of ±0.1mm. Robotic spray production lines achieve uniform three-dimensional fiber distribution. We are building a "GRC Factory of the Future," exploring die-less forming technology based on 3D printing.

Intelligent Installation and O&M Technology

We have developed an AR-based installation guidance system through which workers receive 3D installation instructions via smart glasses. Digital twin models are established for key projects, enabling visualized management of later-stage operation and maintenance. These technologies not only improve installation precision but also lower the construction threshold.

Industry Standards and Construction Method Leadership

Participating in standards development means transforming our own best practices into industry norms. Construction methods we led or contributed to, such as the "Double-Curved GRC Curtain Wall Construction Method," have become important references within the industry. Technical lectures and published papers continuously deliver "Qinglong wisdom."

Therefore, technological advancement is by no means merely theoretical; it is hard capability that runs through the entire process of R&D, design, production, and construction. Through continuous innovation, Qinglong Group is leading the GRC industry toward high performance, high precision, and high efficiency.
