How to Identify Fabricated Cases by GRC Manufacturers?

During the procurement of UHPC/GRC/GRG/GRP materials, the authenticity of case studies is a core basis for evaluating a manufacturer's strength. However, some unscrupulous vendors mislead customers by fabricating project cases and exaggerating the scale of cooperation, planting hidden risks for project quality. As Qinglong Group with 28 years of industry experience, we have drawn on our full-chain service practice to summarize a set of practical methods for scientifically identifying fraudulent GRC manufacturer cases, helping designers and owners avoid risks.

1. Verify the Logic of Basic Case Information

Authentic GRC engineering cases feature a complete timeline and traceable elements. First, you should require the manufacturer to provide project filing information, including official documents such as public bidding records of the construction unit, construction permit numbers, and completion acceptance reports. For example, for the GRC exterior wall works of a landmark project, the bidding announcement can usually be found on government procurement websites or industry platforms, and the construction period must match the manufacturer's production capacity—Qinglong Group's annual capacity of 600,000 square meters can support super-large projects, but if a small manufacturer claims to undertake several million-square-meter-scale projects in the same period, there is an obvious logical contradiction. For overseas cases, authenticity can be verified through the member directory of the International GRC Association or the websites of local building administration authorities; the Southeast Asian projects of Qinglong Malaysia Building Materials Co., Ltd. support cross-border information verification.

2. Analyze the Professional Match of Technical Details

Professional customers should focus on how well the technical parameters of a case match the actual application scenario. Take GRC curtain walls as an example: a qualified manufacturer will provide detailed structural calculation documents specifying key indicators such as glass fiber content (usually ≥5%) and flexural strength (compliant products ≥15MPa), adapted to the wind pressure load and seismic grade of the project location. The Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), which Qinglong participated in formulating, sets clear specifications for material performance in different climate zones; if case parameters conflict with the standard's requirements, fraud may exist. In addition, complex-shape cases should be accompanied by BIM detailed design models or 3D scanning data—for example, for the translucent concrete project at Century Plaza on Nanjing East Road undertaken by Qinglong, the machining precision of the double-curved components can be traced through Rhino model files.

3. Verify the Completeness of the Cooperation Chain

Full-chain service capability is strong proof of case authenticity. It is advisable to require the manufacturer to present complete process documents from design development to after-sales maintenance: the design phase should include communication records with the design institute, the production phase requires raw material procurement vouchers (such as purchase contracts for well-known brand cement and glass fiber roving), and construction and installation should include on-site hoisting plans, concealed works acceptance forms, and the like. As a National High-Tech Enterprise, Qinglong has established a well-developed project archive management system, with each GRC project assigned a dedicated technical lead who can provide full-cycle documentation from detailed design drawings to 5-year maintenance records. For cases claiming cooperation with central state-owned enterprises or well-known real estate developers, cross-verification can be carried out via the supplier directory on the company's official website or cooperation news.

4. On-Site Inspection and Industry Reputation Research

The most direct verification method is to visit the manufacturer's production base and completed projects in person. Observe whether the production line is equipped with automated forming equipment and whether the testing laboratory meets CNAS standards—Qinglong's Guangxi production base, with its CNC spraying units and mechanical performance testing center, can directly demonstrate its production strength. Meanwhile, learn about the manufacturer's reputation through industry association channels; qualifications such as Vice President Unit of the China GRC Association and provincial-level R&D center must be certified by government departments or authoritative institutions. Qinglong has won the Outstanding Contribution Award for Industry Standard Development for many consecutive years, and the authenticity of its cases can be checked through the association's public information. In addition, consult designers and construction contractors in the same industry about their cooperation experiences, and avoid manufacturers showing suspicious behaviors such as "vague case descriptions" or "refusal of on-site visits."

Identifying fraudulent GRC manufacturer cases requires a multi-dimensional approach covering information logic, technical matching, service chain completeness, and on-site verification. Qinglong Group has always upheld the values of "honesty and striving." All project cases can be provided with complete traceability documents, and 58 cumulative patents and 2,000+ successful cases testify to its strength. Only by choosing a qualified manufacturer with full-chain service capability can you ensure project quality and investment safety. For more industry information: +WeChat qlfsbl123
