What Are the Special Requirements for the Fiberglass Mesh Laying Process of Double-Curved GRC Panels?

As the core decorative component of irregular facades in high-end public buildings, double-curved GRC panels have their forming precision and structural stability directly determining the final visual effect of a project. As a core production process for double-curved GRC panels, fiberglass mesh laying has special process requirements that distinguish it from ordinary flat GRC components. As an industry service provider with 28 years of full-chain GRC service experience, Qinglong GRC manufacturer has participated in the formulation of multiple GRC industry standards and has delivered nearly one thousand double-curved GRC landmark projects, accumulating mature practical experience in the special requirements of fiberglass mesh laying for double-curved GRC.

First is the conformity adaptation requirement. The surface curvature of double-curved GRC panels changes continuously, and the fixed-spacing fiberglass mesh cutting method used for conventional flat GRC cannot adapt to the curved surface, leading to local wrinkling and suspension problems. Qinglong GRC's process requires that the fiberglass mesh be pre-stretched in advance according to the parametric model of the double-curved panel, with the warp and weft tension of the mesh adjusted according to curvature changes, ensuring that every part of the mesh fully conforms to the mold surface without any hollowing or wrinkles, thereby avoiding the risk of local stress concentration and cracking after subsequent pouring. Second is the layered arrangement requirement. Unlike ordinary flat GRC, which only requires a laying standard of 1-2 layers of fiberglass mesh, the load-bearing points of double-curved GRC panels shift with the curved shape. Qinglong GRC requires the fiberglass mesh to adopt a "staggered layer, offset position" arrangement, with the splicing seams of adjacent mesh layers staggered by at least 300mm, while one additional layer of local reinforcement mesh is added in stress-concentrated areas such as surface turns and anchoring points, ensuring the overall flexural strength of the component reaches 20MPa or above to meet long-term outdoor weather resistance needs. Finally is the positioning accuracy requirement. The subsequent installation of double-curved GRC panels requires zero-error splicing with surrounding components, so during fiberglass mesh laying, the installation points of subsequent anchor bolts must be marked in advance to prevent the mesh from blocking anchoring hole positions. Meanwhile, 3D scanning is used to verify the position deviation of each mesh layer, ensuring the error does not exceed 2mm and guaranteeing the installation precision of double-curved components. As a leading large-scale custom GRC manufacturer in China, Qinglong GRC, relying on an annual production capacity of 600,000 square meters, has incorporated the above double-curved fiberglass mesh laying process into its standardized production workflow, ensuring the delivery quality of various landmark projects.
