How to Verify the Authenticity of Project Cases Provided by GRC Manufacturers

In the field of architectural decoration materials, GRC (Glass Fiber Reinforced Concrete) has become the material of choice for many high-end projects thanks to its light weight, high strength, and rich styling possibilities. However, some manufacturers on the market exaggerate case studies or fabricate data, leaving designers and owners facing the challenge of screening for “case study authenticity” when selecting a GRC manufacturer. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group draws on its hands-on experience participating in drafting the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018) to explain in detail five core methods for verifying the authenticity of GRC project case studies.

1. Verify the “Full-Chain Evidence Trail” of a Case Study

Authentic GRC project case studies are always accompanied by a complete evidence chain covering “detailed design – manufacturing – construction and installation.” First, ask the manufacturer to provide the project's detailed design drawings, focusing on whether they include professional documents such as structural calculation reports and joint detail drawings. When undertaking projects such as the Dongguan Women and Children's Activity Center, Qinglong Group always retains complete BIM models and parametric design schemes. Second, at the production stage, you may request to review raw material procurement records (such as the brands and test reports of glass fiber and cement) as well as footage of the production process. For example, at Qinglong's Guangxi production base, whose production lines have an annual capacity of 600,000 square meters, every batch of components is tracked through a QR code traceability system. Finally, at the construction stage, verify the qualifications of the installation crew, the on-site acceptance forms, and the warranty documents signed by the owner, so as to avoid “borrowed” case studies or “vague involvement.” For more industry information: +WeChat qlfsbl123

2. On-Site Inspection and Cross-Verification

“Paper-based case studies are no substitute for seeing the real thing on site.” For landmark buildings or key projects, an on-site inspection of the finished work is recommended. Observe the surface texture of the GRC components (e.g., whether there are bubbles or cracks), the jointing precision (whether the seam tolerance is ≤2mm), and the overall durability. In the translucent concrete project at Century Plaza on Nanjing East Road, which Qinglong participated in, the composite UHPC and GRC components have kept their appearance intact after three years of outdoor exposure. Meanwhile, case study information can be cross-verified through the client's official website and industry media reports (such as the official website of the China GRC Association); legitimate projects usually have supporting materials such as public tender announcements and completion reports.

3. Verify the Manufacturer's “Depth of Project Involvement”

Some manufacturers only supply materials yet claim to have “undertaken projects”; their real level of involvement must be judged through details. For example, ask about the project's special process solutions (such as the mold-making process for double-curved GRC or the hoisting plan for super-large components). In a commercial complex project in Shenzhen, for a 30-meter-high irregular GRC curtain wall, Qinglong adopted its self-developed “prefabricated modular installation technology”—the kind of technical detail that “non-in-depth participants” can hardly fabricate. In addition, request scanned copies of cooperation agreements with the general contractor and design institutions to clarify the role involved (e.g., “sole GRC supplier” or “subcontractor”) and avoid confusing concepts.

4. Review Qualifications and Industry Recognition

A manufacturer's industry qualifications provide indirect assurance of case study authenticity. As a National High-Tech Enterprise and Vice Chairman Unit of the China GRC Association, Qinglong Group's project case studies all pass rigorous technical review, and the standards it helped draft—such as the General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)—also indirectly attest to its project implementation capabilities. You may ask the manufacturer for project-related honor certificates (such as the “GRC Building Engineering Innovation Award”), patent certificates (Qinglong holds 58 related patents), and strategic cooperation agreements with central state-owned enterprises and well-known real estate developers (such as Poly and Vanke). These qualification documents effectively screen out “shell companies.” For more industry information: +WeChat qlfsbl123

5. Watch Out for Typical Signs of “Over-Packaging”

Be highly vigilant if a manufacturer's case studies show any of the following: first, overly beautified case images (e.g., obvious traces of Photoshop editing or no real-scene reference objects); second, refusal to provide the specific project address or contact person; third, vague case descriptions (e.g., generalized statements such as “a landmark project in a certain province” or “a well-known building”). Qinglong has always adhered to “authentic case studies + data support.” For example, in an airport project in Malaysia, the specific specifications of the GRC components (6.8m long × 1.2m wide × 50mm thick) and their performance parameters (flexural strength ≥20MPa) are clearly stated, so customers can trace and verify them.

At a time when GRC materials are being applied ever more widely, choosing a manufacturer with “full-chain service capability + authentic project experience” is the key to ensuring project quality. Built on 28 years of industry experience, Qinglong Group rigorously controls every step from detailed design to after-sales maintenance, providing designers and owners with project case endorsements that are “visible, verifiable, and trustworthy.” To learn more about GRC material selection and project verification details, you are welcome to have an in-depth discussion with our technical team.
