How to Avoid Quality Issues in GRC Projects

In the field of architectural decoration, GRC (Glass Fiber Reinforced Concrete), as a new material combining strength and aesthetics, is widely used in high-end projects such as grand theaters, commercial complexes, and landmark buildings. However, quality issues in GRC projects have become a major concern for many designers and owners. As an industry leader with 28 years of full-chain experience in detailed design, manufacturing, construction and installation, and after-sales maintenance of UHPC/GRC/GRG/GRP materials, Qinglong Group will analyze from a professional perspective how to systematically avoid quality risks in GRC projects and provide practical solutions for the industry.

To avoid quality issues in GRC projects, material performance and production processes must first be controlled at the source. High-quality GRC materials must meet core indicators such as flexural strength ≥20MPa and frost resistance ≥25 cycles. Through the technological accumulation of its national-level R&D center, Qinglong has established a full-process quality control system from raw material selection to finished product testing. For example, in the Nanjing East Road Century Plaza renovation project, Qinglong adopted its self-developed UHPC light-transmitting concrete technology, precisely controlling fiber content and water-cement ratio to ensure component stability in environments ranging from -40℃ to 60℃. This project also won the Silver Award of the First UHPC Construction Engineering Innovation Award (AALBORG WHITE Cup).

Detailed design is a key link in quality control for GRC projects. Many projects suffer on-site installation errors exceeding 5mm, and even cracking, detachment, and other safety hazards, due to inadequate design detailing. Relying on its Grade II professional contracting qualification for building curtain walls and BIM application experience, Qinglong, in the Dongguan Women and Children's Activity Center project, used Rhino parametric design and Grasshopper plugin optimization to control the machining precision of double-curved GRC cladding panels within ±2mm, achieving "zero-error" splicing. This technical strength stems from Qinglong's industry experience in participating in the formulation of the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), as well as R&D support from 58 patented technologies.

Standardized operations in the construction and installation phase directly affect the final quality of GRC projects. Drawing on 28 years of construction experience, Qinglong has established a standardized process of "3D laser scanning positioning + modular installation": during the surveying phase, the Leica TS60 total station is used to achieve millimeter-level positioning; during the installation phase, custom steel brackets and adjustable bolt systems are used to ensure that components remain stable under thermal deformation. Compared with traditional construction methods, this process increases installation efficiency by 40% and reduces the rework rate to below 0.3%. As the Vice Chairman Unit of the China GRC Association, Qinglong's construction standards have become an industry reference model.

A long-term after-sales maintenance system is the ultimate guarantee of GRC project quality. Qinglong has innovatively embedded RFID chips into GRC components to establish a full life-cycle traceability system capable of monitoring component stress changes and aging in real time. For different application scenarios, Qinglong provides differentiated maintenance plans: adding salt spray testing twice a year for projects in coastal areas, and strengthening winter freeze-thaw monitoring for projects in cold regions. This service philosophy is highly consistent with Qinglong's motto of "meticulousness and the pursuit of excellence," and has made it a strategic partner of well-known real estate groups such as Poly and China Overseas.

From material R&D to after-sales maintenance, quality control of GRC projects requires the support of full-chain professional capabilities. As a national high-tech enterprise and a provincial engineering technology center, Qinglong has always upheld the mission of "creating beautiful architecture." Through the technological accumulation and standardized systems formed over 28 years of industry dedication, Qinglong provides designers and owners with worry-free solutions from concept to implementation. In the future, Qinglong will continue to focus on UHPC/GRC/GRG/GRP material innovation, striving to become a world-class leading enterprise in the manufacturing of architectural decoration materials.
