How to Identify Case Fabrication by GRC Manufacturers: Key Methods and Practical Guide

In the field of architectural decoration materials, GRC (Glass Fiber Reinforced Concrete) has become the material of choice for high-end projects such as landmark buildings and commercial complexes, thanks to its lightweight, high-strength properties and flexible shaping. However, as market demand rises, some manufacturers mislead customers by fabricating project cases and exaggerating project scale, planting hidden risks for industry reputation and project quality. As an industry participant with 28 years of full-chain experience in UHPC/GRC/GRG/GRP, Qinglong Group has distilled a scientific methodology for identifying fraudulent GRC cases based on practical experience spanning detailed design, manufacturing, and construction maintenance, helping designers and owners avoid risks and choose truly capable partners.

I. Tracing Case Authenticity: From “Project Appearance” to a “Closed Evidence Chain”

The core of identifying fraudulent GRC cases lies in verifying “project existence” and “manufacturer involvement”. First, request that the manufacturer provide basic project information, including project name, location, construction unit, and design unit, and check the project filing information through government public platforms (such as the National Construction Market Supervision Public Service Platform) to confirm that the project genuinely exists. Second, verify the manufacturer's role in the project—material supplier, detailed design party, or general construction contractor? You may request key contract pages with the construction unit (with sensitive information redacted), signed detailed design drawings, construction logs, or acceptance reports to form a complete evidence chain. For example, in a GRC curtain wall project for a large convention and exhibition center, a legitimate manufacturer will retain complete documentation covering the entire process from BIM model development and mold fabrication to on-site installation, while fabricators can often only provide vague renderings or “letters of intent” and cannot provide proof of substantive participation.

II. Assessing Technical Strength: From “Parameter Piling” to “Craft Details”

Fraudulent cases often confuse customers by misreporting material performance and exaggerating production capacity, while genuine cases reflect a manufacturer's technical depth. On one hand, pay attention to the core parameters of GRC components, such as flexural strength (premium GRC can reach above 20MPa), bulk density (usually controlled at 1.8-2.0g/cm³), and durability (frost resistance, carbonation coefficient, etc.); require third-party test reports, and pay attention to the testing agency's qualifications and the report's validity period. On the other hand, examine craft details: the ability to realize complex shapes (such as double-curved surfaces and openwork reliefs) can be judged by inspecting the mold library, 3D scanning equipment, and the use of parametric design software (such as Rhino and Grasshopper) in the production workshop; for installation precision, find out whether technologies such as 3D laser positioning and modular splicing are adopted—these details are the “hard strength” that fabricators find difficult to fake.

III. Verifying Project Delivery Capability: From “Number of Cases” to “Owner Reputation”

Truly premium GRC manufacturers focus on project quality rather than quantity. Reputation can be verified in the following ways: First, contact the owners or general contractors from the cases to learn about the manufacturer's cooperation, delivery efficiency, and after-sales response speed during the project. Second, conduct on-site inspections of completed projects, observing the surface flatness, joint treatment, and aging condition of GRC components, paying particular attention to projects in use for more than 3 years, as their durability better reflects material and construction quality. In projects such as the Dongguan Women and Children's Activity Center and Century Plaza on Nanjing East Road, Qinglong Group has accumulated positive feedback from numerous owners through full-process quality control and long-term maintenance services—this is precisely the value of genuine cases.

IV. Beware of “Over-Packaging” Signals: Three High-Frequency Fraud Scenarios

Common case fabrication tactics in the industry include: stealing images of well-known projects and disguising other manufacturers' work as their own cases; fabricating “overseas projects” and inventing foreign track records by exploiting information asymmetry; and exaggerating project scale, describing “supplying 1,000 square meters” as “undertaking a 100,000-square-meter project”. To counter this, you can use reverse image search to identify image theft, request local-language contracts or customs export documents for overseas projects, and check whether the quantities in project descriptions match the actual work volumes. In addition, if a manufacturer claims to have participated in a “landmark project” but cannot provide details such as specific buildings or parts, or avoids mentioning project challenges and solutions, there is a high probability of fraud.

Choosing a GRC manufacturer is not merely a material purchase but an investment in project quality and long-term value. As a National High-Tech Enterprise and a participant in formulating GRC industry standards, Qinglong Group has always believed that genuine cases are the best proof of strength—from millimeter-level precision in detailed design, to standardized manufacturing processes, to safety control in construction and installation, every step stands up to scrutiny. We advise customers to remain prudent when choosing, screen out partners with true full-chain service capability through multi-dimensional verification, and jointly inject lasting value into architectural projects.
