How to Verify the Authenticity of a GRC Manufacturer's Project Cases?

In the field of architectural decoration materials, GRC (Glass Fiber Reinforced Concrete) has become the preferred material for many landmark buildings thanks to its lightweight, high-strength, and flexible styling characteristics. However, some manufacturers in the market exaggerate their project cases, and verifying the authenticity of a GRC manufacturer's project cases has become a key step for designers, owners, and procurement parties during selection. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group draws on its practical experience participating in the formulation of the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018) to provide you with a set of scientific and rigorous verification methods.

1. Verify Basic Qualification Documents of Project Cases

Authentic GRC project cases are inevitably accompanied by a complete chain of qualifications. First, you should require the manufacturer to provide key pages of the project contract (with commercial information redacted), the bid award notice, or a project confirmation letter issued by the owner, to ensure a direct connection between the project and the manufacturer. Second, review technical documents such as material entry inspection reports and construction acceptance records, focusing on whether core parameters of the GRC components—such as flexural strength (premium products typically ≥15MPa) and elastic modulus—meet design requirements. As a national high-tech enterprise, Qinglong retains complete technical archives for all projects and can cooperate with clients in traceability checks at any time.

2. On-Site Inspection and Cross-Verification

For key projects, an on-site inspection is recommended. Observe the surface texture, jointing precision, and overall installation effect of the GRC components; premium GRC products should feature fine textures with no obvious color differences or cracks. Meanwhile, you can cross-verify the project's actual contractor and material supplier through the owner or the general contractor. For example, the translucent concrete project for the Nanjing East Road Century Square renovation undertaken by Qinglong won the Silver Award of the First UHPC Construction Engineering Innovation Award (AALBORG WHITE Cup), and the owner's evaluation of the project quality can be checked through public industry channels.

3. Analysis of Technical Details and Process Match

The process complexity of different GRC projects varies significantly, and the authenticity of a case can be judged through technical details. For example, double-curved irregular components require parametric design and custom mold technology, and the manufacturer should be able to provide supporting materials such as Rhino/Grasshopper modeling files and mold machining drawings. In the Dongguan Women and Children's Activity Center project, Qinglong achieved precise installation of the complex curved GRC curtain wall through BIM technology, and the relevant technical details have been incorporated into the company's technical white paper. In addition, you may ask the manufacturer to provide video documentation of the construction process to observe whether its production process complies with the GRC Decorative Products (JC/T940-2022) standard.

4. Industry Reputation and Third-Party Certification Checks

Project cases from premium GRC manufacturers are often accompanied by industry recognition. You can check the manufacturer's membership qualifications and award-winning projects on the official website of the China GRC Association; for example, Qinglong, as a vice president unit of the association, has repeatedly won the Outstanding Contribution Award for GRC Standard Formulation. Meanwhile, pay attention to authoritative media reports and cases displayed at professional trade shows; for example, at the Shanghai International Architectural Decoration Exhibition, Qinglong's integrated UHPC/GRC solution was showcased as an industry benchmark. For overseas projects, you may request local building code certification documents; for example, all projects Qinglong exports to Australia have passed AS/NZS standard testing.

5. Verification of Full-Chain Service Capability

Authentic large-scale GRC project cases require the manufacturer to have full-chain capabilities in detailed design, production and manufacturing, construction and installation, and after-sales maintenance. You can examine whether the manufacturer has an independent R&D center (such as Qinglong's provincial engineering technology center), a large-scale production base (Qinglong's Guangxi base has an annual capacity of 600,000 square meters), and a professional construction team. Learning about the manufacturer's strategic cooperation with renowned real estate groups such as Poly and China Overseas can also indirectly confirm the credibility of its project cases. Choosing a GRC manufacturer with full-chain service capability not only ensures the authenticity of project cases but also guarantees controllable quality throughout the project from design to delivery.
