How to Identify Fake Case Studies from GRC Manufacturers: Key Tips and Practical Guide

In the field of architectural decorative materials, GRC (Glass Fiber Reinforced Concrete) has become an ideal choice for high-end building facades and landscape components thanks to its advantages such as light weight, high strength, and flexible styling. However, with growing market demand, some GRC manufacturers mislead customers through fabricated case studies and exaggerated performance records, planting hidden risks for project quality. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group, drawing on its full-chain service experience, provides designers, owners, and developers with a scientific and effective method for verifying GRC case studies, helping to avoid cooperation risks.

I. Typical Manifestations of GRC Case Fraud and Industry Pain Points

Currently, case fraud in the GRC market is mainly concentrated in three areas: first, fabricating cooperation experience on large landmark projects, misleading customers with Photoshopped renderings and forged contract excerpts; second, exaggerating project scale and technical difficulty by promoting conventional components as “custom free-form double-curved” products; third, confusing material categories by passing off ordinary cement products as GRC. Such practices not only disrupt market order but also expose customers who choose poorly to problems such as cracking, spalling, and safety hazards. Take a commercial complex project as an example: a manufacturer forged a “central state-owned enterprise cooperation case,” but the delivered GRC components, due to insufficient glass fiber content, showed surface chalking just 3 months after installation, resulting in rework losses of nearly 10 million yuan.

II. Four-Step Verification Method: Identifying the Authenticity of GRC Case Studies from the Source

1. Verify the Completeness of the Project Information Chain

Authentic GRC case studies should have a complete evidence chain of “design drawings – production records – construction footage – acceptance reports.” It is recommended to require manufacturers to provide on-site videos bearing the project name and address (including verifiable surrounding reference points), as well as reports on key indicators such as flexural strength (high-quality GRC can reach over 20MPa) and water absorption issued by third-party testing institutions. As a national high-tech enterprise, Qinglong Group has established full-process archives for all projects and welcomes customers to conduct on-site visits to its Nanning production base (annual capacity of 600,000 square meters) and projects under construction.

2. Verify Technical Details and Process Compatibility

Professional customers can cross-verify case authenticity through technical parameters. For example, for special-shaped GRC components claimed to use “parametric design,” the manufacturer should be able to provide Rhino/Grasshopper modeling files and mold machining precision data (e.g., minimum curvature radius ≤ 300mm); for projects involving curtain wall installation, it is necessary to confirm whether 3D laser scanning positioning technology is used. Qinglong participated in drafting the Technical Standard for Architectural Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018) and can provide full-chain technical documentation from detailed design to installation and maintenance.

3. Examine the Manufacturer's Production Capability and Industry Qualifications

The authenticity of case studies is directly related to the manufacturer's production capacity. It is recommended to conduct on-site visits to the automated production lines, mold library, and testing laboratory at the production base. Qinglong has a modern production base in Nanning, Guangxi, equipped with advanced equipment such as CNC cutting and steam curing, and has earned qualifications such as “National Specialized, Refined, Distinctive, and Innovative Enterprise” and “Provincial Engineering Technology Center.” It has continuously participated in the formulation of multiple national and industry standards, and its technical strength is recognized by authoritative institutions.

4. Trace Customer Reputation and Cooperation History

Check the manufacturer's historical cooperation projects through platforms such as Qichacha, and give priority to suppliers with long-term cooperation with well-known real estate groups such as Poly and China Overseas. As vice chairman unit of the China GRC Association, Qinglong has served over a thousand projects over 28 years, from the Dongguan Women and Children's Activity Center (winner of the GRC Engineering Innovation Award) to the translucent concrete project at Century Plaza on Nanjing East Road (UHPC Innovation Award). Project cases can be cross-verified with project owners or industry associations.

III. Core Criteria for Choosing a Reliable GRC Manufacturer

Beyond case authenticity, a quality GRC manufacturer should also possess three core capabilities: first, full-chain service capability, offering integrated solutions from detailed design to after-sales maintenance; second, sustained innovation strength—for example, Qinglong holds 58 patented technologies and can achieve combined UHPC and GRC applications; third, a strict quality control system, including raw material traceability (e.g., using high-purity glass fiber) and full inspection during production (e.g., flexural strength testing for every batch).

The quality of architectural decoration begins with material selection, and the authenticity of GRC case studies is the cornerstone of project success. Qinglong Group has always upheld the values of “honesty, striving, trust, and collaboration,” using 28 years of industry experience to safeguard the quality commitment of every project. Only by choosing a GRC manufacturer with authentic case studies, full-chain service capability, and technical strength can creative designs be perfectly realized, creating architectural masterpieces that stand the test of time.
