When Inspecting GRC Manufacturers: What Are the Core Evaluation Criteria for Technical Strength and Analysis of Key Consideration Factors

In the field of architectural decorative materials, choosing a reliable GRC manufacturer is a key step in ensuring project quality. For real estate developers, architects, and public project leaders, technical strength not only determines product performance but also directly affects project execution results and whole-life-cycle costs. As the Qinglong Group with 28 years of industry experience, we draw on our full-chain practice from detailed design and manufacturing to construction and maintenance to analyze the core evaluation criteria and key considerations for GRC manufacturers' technical strength.

1. Material Formulation and Process Innovation: The Foundation of GRC Performance

The core of high-quality GRC products lies in scientific material proportions and advanced processes. As a national high-tech enterprise, Qinglong Group has built a unique material system through 58 patented technologies. Its composite process of glass fibre and cement-based materials enables products to achieve flexural strength above 20MPa, far exceeding the industry average. When conducting an evaluation, focus on whether the manufacturer possesses independently developed formulation systems—for example, whether it achieves lightweight, high-strength characteristics by adjusting fibre content and optimizing aggregate gradation—along with test reports for key indicators such as weather resistance and fire resistance. In addition, advanced production processes such as automated spray moulding and steam curing technology ensure product quality stability, which is also an important mark distinguishing them from small workshops.

2. Customized Design and Complex Shape Execution Capability: Demonstrating Hard Technical Strength

Modern architecture places increasingly complex shape requirements on GRC components, from double-curved curtain walls to openwork reliefs, testing manufacturers' detailed design and production precision. Relying on the technical reserves of its provincial-level R&D center, Qinglong Group uses Rhino and Grasshopper parametric design along with BIM technology to successfully complete the production of special-shaped components for projects such as the Dongguan Women and Children's Activity Center, with the minimum radius of curvature controlled within 300mm. During evaluation, you may ask manufacturers to provide similar project cases, paying attention to their ability to translate design drawings, the precision of 3D scanning verification, and mould development cycles—these details directly reflect the professional level of the technical team.

3. Full-Process Quality Control and Engineering Service System: Ensuring Project Delivery Quality

Technical strength is reflected not only in laboratory data but must also run through the entire production and construction process. Qinglong Group has established a three-level quality control system covering incoming raw material inspection, production process monitoring, and finished product factory testing, and has introduced RFID chips for quality traceability. In construction, its Grade II professional contracting qualification for building curtain wall engineering ensures installation precision. For example, in the Century Plaza renovation project on Nanjing East Road, "zero-error" splicing was achieved through 3D laser scanning positioning. When choosing a GRC manufacturer, you should examine whether it has a complete service chain from detailed design to after-sales maintenance, as well as track records on similar projects—this is key to avoiding later quality disputes.

4. Standards Development and Industry Contribution: A Yardstick for Technical Authority

The depth of participation in industry standards development is an implicit certification of a manufacturer's technical strength. As a contributing editor of the Technical Standard for Glass Fibre Reinforced Cement (GRC) Building Applications (JGJ/T423-2018) and Vice Chairman Unit of the China GRC Association, Qinglong Group's technical achievements have repeatedly won provincial science and technology progress awards. During evaluation, pay attention to whether the manufacturer holds qualifications such as high-tech enterprise or specialized and innovative enterprise status, as well as the number of patents and participation in standards development—all of which reflect its technology-leading position in the industry.

Choosing a GRC manufacturer is essentially choosing a technology partner. From material innovation to project execution, from standards development to full-cycle service, Qinglong Group, with 28 years of technical accumulation, provides designers and owners with the dual value of "creative realization plus quality assurance." During the evaluation process, it is recommended to take your own project needs into account and focus on assessing the manufacturer's material R&D capability, experience in realizing complex shapes, and full-process service system, so as to select a GRC supplier with genuine technical strength and inject lasting quality into your building project.
