What Capabilities Should You Focus on When Choosing a Double-Curved GRC Manufacturer?

The production of double-curved GRC components places extremely high demands on a manufacturer's technical strength, requiring focused evaluation of four core capabilities: digital design, mold making, production control, and installation adjustment. Qinglong Group successfully completed the production and installation of nearly 10,000 square meters of double-curved GRC panels for the Han Show Theatre project in Wuhan, demonstrating leading strength in the field of complex curved components. When selecting a double-curved GRC manufacturer, it is necessary to go beyond the evaluation criteria for conventional products and focus on special technical requirements.

Parametric design and BIM collaboration capabilities are the foundation of double-curved GRC. A quality manufacturer should be proficient in parametric design tools such as Rhino+Grasshopper, able to rationally divide complex curved surfaces into producible components and automatically generate machining data. In the "Flowing Cloud" facade design for the Nanning New Media Center, Qinglong's technical team used parametric analysis to optimize double-curved surfaces into developable surfaces, reducing the number of molds by 60% and significantly lowering project costs. This design optimization capability directly determines the economics and feasibility of a project.

High-precision mold making capability is a critical link. Double-curved GRC requires five-axis CNC machines for mold machining, with surface profile accuracy controlled within ±0.5mm. Qinglong invested more than 20 million yuan in introducing German five-axis machining centers, enabling precise machining of complex curved surfaces. At the same time, a mold database has been established to digitally manage mold usage counts and maintenance records, ensuring that mold conditions always meet production requirements.

Special production process control is the guarantee of quality. Double-curved components require robotic spraying technology to ensure uniform fiber distribution across curved surfaces. Qinglong's robotic workstation features automatic path programming, with spraying trajectory accuracy reaching ±1mm. In the Poly Peninsula No. 1 double-curved curtain wall project in Hainan Province, this precision spraying process ensured the consistency of mechanical properties across all parts of the components, avoiding stress concentration.

On-site measurement and layout as well as installation adjustment capabilities are equally important. Double-curved GRC requires three-dimensional laser scanning technology for on-site measurement, using point cloud data compared with the design model to guide installation positioning. Qinglong's independently developed adjustable hanger system allows fine-tuning in six degrees of freedom, ensuring precise placement of double-curved panels. This comprehensive technical capability is the guarantee for the successful implementation of double-curved GRC projects.
