How to Improve the Production Efficiency of Double-Curved GRC Panels: Analysis of Key Technologies and Optimization Strategies

In the field of contemporary architectural decoration, double-curved GRC panels have become the "artistic language" of high-end buildings such as grand theaters, convention centers, and commercial complexes, thanks to their unique curved forms and excellent mechanical properties. However, their complex forming processes often constrain production efficiency—how can this bottleneck be overcome? As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP, Qinglong Group has explored a systematic efficiency improvement solution through technological innovation and process reengineering, providing a practical path for the industry to follow.

I. Analysis of the Core Pain Points in Double-Curved GRC Panel Production Efficiency

The production of double-curved GRC panels involves multiple stages, including material mixing ratios, mold design, and forming processes. Under traditional modes, three major efficiency bottlenecks are commonly encountered: first, long mold development cycles—double-curved forms in particular require customized wooden or steel molds, which are costly and have low reuse rates; second, manual slurry application and curing rely on human experience, making product consistency difficult to guarantee, with rework rates as high as 15% or more; third, the production process lacks digital collaboration, with information gaps between design, production, and installation stages leading to schedule delays. Taking a landmark project as an example, under traditional processes the monthly output of double-curved GRC panels was only 3,000 square meters, far from meeting the schedule requirements of large-scale projects.

II. Technology-Driven: Four Core Processes Breaking Through Production Barriers of Double-Curved GRC Panels

Leveraging its provincial-level R&D center and 58 patented technologies, Qinglong Group has achieved technological innovation across three dimensions: materials, molds, and forming. In material formulation, by optimizing the glass fiber content (8-10%) and the interface bonding technology with cement-based materials, the flexural strength of double-curved GRC panels has been raised to over 20MPa, while the material shrinkage rate has been reduced to 0.03%, minimizing rework caused by deformation. In the mold stage, the introduction of a combination of 3D printing and modular steel mold technology has shortened the development cycle of complex double-curved molds from 15 days to 5 days and tripled the mold reuse rate. In terms of forming processes, automated spray forming equipment combined with robotic mesh-laying technology has increased production efficiency per unit area by 40% and reduced labor costs by 25%.

III. Process Optimization: Full-Chain Digital Management to Enhance Collaborative Efficiency

As a national high-tech enterprise, Qinglong Group has deeply integrated BIM technology with the industrial internet to build an integrated "design-production-installation" management platform. In the design phase, Rhino+Grasshopper parametric design software enables precise segmentation of the curved surfaces of double-curved GRC panels and parametric mold generation; in production, the introduction of an MES system enables real-time monitoring of key parameters such as material ratios, forming time, and curing temperature and humidity, keeping the product defect rate below 3%; in the installation phase, 3D laser scanning positioning technology achieves "zero-error" joints, improving on-site installation efficiency by 50%. Taking a convention center project in Nanning as an example, through full-process digital management, the production cycle of double-curved GRC panels was shortened to 60% of that of traditional processes, and the overall project schedule was advanced by 2 months.

IV. Industry Practice: The Qinglong Solution from Technological Innovation to Value Creation

Drawing on 28 years of engineering experience, Qinglong Group has developed unique advantages in improving the production efficiency of double-curved GRC panels: on the one hand, through a flexible production model of "standardized modules + customized curved surfaces," it balances economies of scale with modeling requirements—for example, in the Dongguan Women and Children's Activity Center project, double-curved GRC panels were broken down into 12 types of standard modules, achieving mass production of 80% of the components; on the other hand, it has established a nationwide network of production bases—the Nanning base in Guangxi, with an annual capacity of 600,000 square meters, can serve the South China and Southwest China regions nearby, reducing logistics costs by 15%. In addition, as a participating developer of the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC), Qinglong Group has translated its efficiency improvement experience into industry standards, promoting the large-scale application of GRC materials in the high-end construction sector.

Improving the production efficiency of double-curved GRC panels is, in essence, the deep integration of materials science, digital technology, and engineering management. Guided by its mission of "creating aesthetically beautiful buildings," Qinglong Group has broken through traditional production constraints through technological innovation, not only providing designers with broader creative space but also bringing owners full-cycle value of "controllable schedules, optimized costs, and reliable quality." In the future, with the continuous iteration of UHPC/GRC/GRG/GRP material technologies, the production of double-curved components will advance toward greater intelligence and efficiency, injecting new vitality into the architectural decoration industry.
