How to Establish a Full-Lifecycle Quality Management System for GRC Projects?

In the field of architectural decoration, new materials such as GRC (Glass Fiber Reinforced Concrete), UHPC (Ultra-High Performance Concrete), GRG (Glass Fiber Reinforced Gypsum), and GRP (Glass Reinforced Thermosetting Plastic, commonly known as fiberglass), with their unique properties, have been widely applied in high-end buildings such as grand theaters, convention and exhibition centers, and commercial complexes. However, quality control of GRC engineering projects has always been a focus of industry attention, and establishing a full life-cycle quality management system has become the key to ensuring project quality. As an industry leader with 28 years of full-chain experience in detailed design, manufacturing, construction and installation, and after-sales maintenance, Qinglong Group has accumulated extensive practice in the quality management of GRC and other materials. This article analyzes the core points of building such a system from a full life-cycle perspective.

I. Design Phase: Laying the Quality Foundation with Technological Innovation

Design is the source of quality in GRC engineering projects, requiring precise planning that combines material properties with project requirements. Relying on its provincial-level R&D center and 58 patented technologies, Qinglong Group focuses on three key tasks during the design phase: first, deepening parametric design, using tools such as Rhino and Grasshopper to digitally model complex shapes like hyperbolic surfaces and openwork reliefs, ensuring component dimensional errors are controlled within ±2mm; second, optimizing material formulations, adjusting glass fiber content and cement grade according to the project environment (e.g., coastal areas require enhanced salt spray resistance), so that GRC components maintain a stable flexural strength above 20MPa; third, conducting structural safety simulations, using BIM technology to perform simulation analysis of anchoring systems and load distribution to avoid later installation hazards. Taking the Nanjing Road Century Plaza renovation project as an example, its translucent concrete project achieved a perfect unity of aesthetic effect and structural safety through repeated verification during the design phase, winning the Silver Award of the first AALBORG WHITE Cup UHPC Construction Engineering Innovation Award.

II. Manufacturing: Ensuring Product Consistency with Standardized Processes

The production stage is the core of quality control, requiring standardized and intelligent means to ensure stable product quality. Qinglong Group has established a modern production line covering 600,000 square meters at its production base in Nanning, Guangxi, implementing a “three-inspection system” for quality control: in the raw material inspection stage, key materials such as glass fiber and cement are re-inspected upon arrival, rejecting unqualified raw materials; during production process inspection, automated mixing equipment controls mix ratio precision, and 3D scanning technology monitors component forming quality in real time; at the finished product inspection stage, performance tests such as flexural and impact resistance are conducted in accordance with the standard “Glass Fiber Reinforced Cement (GRC) Decorative Products” JC/T940-2022, ensuring a 100% factory pass rate. In addition, the company has introduced an RFID chip traceability system, where each GRC component can be queried for information such as production batch and curing records, making quality responsibility fully traceable.

III. Construction and Installation: Achieving “Zero-Error” Joining with Precision Craftsmanship

The precision of construction and installation directly affects the final presentation. With its Grade II professional contracting qualification for building curtain wall engineering, Qinglong Group has innovatively adopted the “3D positioning + modular installation” process: before construction, 3D laser scanning technology is used to survey the site, generating point cloud models to compare with design models and preemptively avoiding structural deviations; during installation, customized tooling fixtures are used to ensure component positioning errors ≤3mm, while elastic connection technology is employed to accommodate thermal deformation and avoid cracking risks. In the Dongguan Women and Children’s Activity Center project, this process successfully solved the installation challenges of super-large irregular GRC components, winning the Silver Award of the first AALBORG WHITE Cup GRC Construction Engineering Innovation Award. For special scenarios such as GRG ceilings and GRP daylighting roofs, the company has also formulated specialized construction plans, such as using a “suspended” hoisting system for GRG installation to reduce load impact on the base structure.

IV. After-Sales Maintenance: Enhancing Project Value with Full-Cycle Service

After-sales service is an extension of quality management. Qinglong Group has established a nationwide maintenance network providing full-cycle service from completion acceptance to long-term care: during regular inspections, GRC/UHPC components undergo annual visual inspection and structural safety assessments, with timely handling of issues such as surface weathering and loose anchoring; for emergency response, the company promises to arrive on site within 24 hours and propose solutions within 48 hours; in addition, the company provides customers with material maintenance guidance, such as cleaning methods for GRG components and renewal cycles for UHPC surface protective coatings, helping extend project service life. This “one-stop” service model has made Qinglong a strategic partner of well-known real estate groups such as Poly, China Overseas, and Vanke, with products exported to overseas markets such as Malaysia and Australia.

Conclusion: Building a full life-cycle quality management system requires enterprises to form closed-loop control across all stages of design, production, construction, and maintenance. As a National High-Tech Enterprise and a Specialized, Refined, Distinctive, and Innovative enterprise, Qinglong Group has always upheld the principle of “meticulousness and excellence,” providing reliable quality assurance for GRC engineering projects through technological innovation, standardized management, and full-chain services. In the future, with the implementation of industry standards such as “General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC),” Qinglong will continue to play a leading role in standard-setting and promote the high-quality development of the new architectural decoration materials industry.
