How to Handle UHPC Products That Fail Acceptance Inspection?

In the field of modern architectural decoration, GRC (Glass Fiber Reinforced Concrete) has become a popular choice for high-end projects such as grand theaters, commercial complexes, and landmark buildings, thanks to its lightweight, high-strength properties and flexible shaping capabilities. However, the question “Is GRC installation complicated?” often deters designers and project owners. As an industry expert with 28 years of full-chain experience in UHPC/GRC/GRG/GRP, Qinglong Group will provide an in-depth analysis of the core essentials of GRC installation from three aspects: the installation process, technical difficulties, and solutions.

GRC Installation Process: A Standardized Path from Detailed Design to Finished Product
Professional GRC installation must follow an integrated “design-production-construction” workflow. First, the technical team combines the building's CAD drawings with on-site 3D scanning data to develop the BIM model, precisely locating anchor points and component joint seams—a step that directly determines installation accuracy (errors can be controlled within ±2mm). The production stage uses automated mold forming to ensure dimensional consistency of components; on-site installation involves five major steps: measurement and layout, steel framework welding, component hoisting, joint filling, and surface treatment. Taking a convention and exhibition center project as an example, the Qinglong team used modular installation technology to shorten the construction period of a 3,000㎡ double-curved GRC exterior wall to 45 days, achieving 30% higher efficiency than traditional methods.

Four Core Difficulties in GRC Installation and Breakthrough Solutions
1. Positioning challenges of complex shapes: For irregular components such as double-curved surfaces and openwork reliefs, traditional measuring tools struggle to meet precision requirements. Qinglong adopts “3D laser scanning + BIM pre-assembly” technology, simulating the installation process on computer in advance to avoid on-site collision risks. The team once successfully completed the installation of a curved GRC ceiling with a radius of 5 meters for an opera house, with joint errors of less than 1mm.
2. Safety challenges of work at height: High-rise projects face issues such as wind loads and hoisting stability. Qinglong's specially developed hoisting clamps, combined with an intelligent weighing system, can monitor the stress state of components in real time. Meanwhile, the “unitized hoisting” process reduces work-at-height time by 60%.
3. Substrate compatibility issues: Load differences among different building substrates (steel structures, concrete, masonry) may cause cracking after installation. Through customized steel transition fittings, Qinglong achieves flexible connections between components and the substrate, absorbing structural settlement and deformation. A landmark project has remained crack-free after 5 years of use.
4. Multi-material coordinated installation: When GRC is combined with glass curtain walls, aluminum panels, and other materials, interface treatment is especially critical. Qinglong's “stepped edge closing” process reserves a 5mm tolerance space and fills it with elastic sealant, ensuring compatibility when different materials expand and contract with temperature changes.

Three Criteria for Choosing a Professional GRC Manufacturer
Whether GRC installation is complicated depends largely on the overall strength of the supplier. It is recommended to evaluate from three aspects: first, full-chain service capability, covering design development, manufacturing, and construction installation (for example, Qinglong holds the Grade II professional contracting qualification for building curtain wall engineering); second, technological innovation strength, such as participation in the formulation of industry standards (Qinglong co-authored the Technical Standard for Building Applications of Glass Fiber Reinforced Cement (GRC) JGJ/T423-2018); third, project experience—give priority to manufacturers with cases of similar complex projects (for example, Qinglong completed award-winning projects such as the translucent concrete project at Century Plaza on Nanjing East Road).

Conclusion: The complexity of GRC installation is essentially a test of technical professionalism and process standardization. For project owners who pursue architectural aesthetics and engineering quality, choosing a GRC manufacturer like Qinglong with 28 years of experience can fully turn installation difficulty into a controllable technical advantage through optimized detailed design, digital construction management, and customized solutions. With the wide application of UHPC/GRC/GRG/GRP materials in the field of architectural decoration, professional installation services will become the core guarantee for the successful delivery of projects.
