How to Verify the Authenticity of Qualification Certificates Provided by UHPC Manufacturers?

In the procurement of UHPC materials, qualification certificates are an important basis for assessing a manufacturer's overall strength. However, issues such as forged qualifications and expired certificates occur from time to time in the market. How to accurately verify the authenticity of the qualification certificates provided by UHPC manufacturers has become a key concern for designers, owners, and purchasers. As an industry leader with 28 years of deep expertise in the UHPC/GRC/GRG/GRP materials field, Qinglong Group will draw on its full-chain experience to provide you with professional identification methods.

### I. Core Dimensions for Verifying Qualification Certificates: From Authority to Validity

First, it is necessary to clarify the authoritative certification systems for UHPC material qualifications. Legitimate UHPC manufacturers should possess basic qualifications such as a National High-Tech Enterprise Certificate and Specialized, Refined, Distinctive, and Innovative Enterprise recognition, which can be verified through the National Enterprise Credit Information Publicity System and the official websites of local science and technology departments. Taking Qinglong Group as an example, its 58 patents and its participation in formulating industry standards such as the "General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components" can all be verified through official channels such as the Ministry of Housing and Urban-Rural Development and the China GRC Association. In addition, special attention should be paid to the validity period and annual inspection records of certificates to avoid using expired qualifications.

### II. Cross-Verification of Technical Documents and Production Capacity

The authenticity of qualification certificates must form a closed loop with actual production capacity. It is recommended to require manufacturers to provide raw material test reports (e.g., for steel fibers and cement), production process flowcharts, and product performance test reports issued by CNAS-accredited laboratories (covering key indicators such as compressive strength ≥150MPa and elastic modulus ≥40GPa). Qinglong Group's annual production capacity of 600,000 square meters and its on-site inspection support at the Nanning, Guangxi production base can be further confirmed through satellite maps, factory video calls, and other means. Meanwhile, reviewing the client acceptance documents of the manufacturer's past project cases (such as landmark buildings and large municipal projects) can further substantiate the practical application value of the qualifications.

### III. Verification of Endorsements from Industry Associations and Third-Party Organizations

Membership in authoritative industry organizations is an important reference. For example, statuses such as Vice President Unit of the China GRC Association and member of the International GRC Association can be verified through the member directories on the associations' official websites. As the President Unit of the Guangdong Fiber Composite Materials Industry Association, Qinglong Group's industry standing can be directly found in the association's public information. In addition, certification results from third-party credit rating agencies (such as AAA-level Credit Enterprise) and financial qualifications such as bank credit certificates can reflect the manufacturer's compliant operation from another angle.

### IV. Practical Advice: Building a Qualification Verification Checklist

To improve verification efficiency, it is recommended to create a checklist containing the following elements: 1. Cross-checking certificate numbers against the issuing authority's official website; 2. Consistency between the enterprise name and the certificate subject; 3. Match between the qualification level and project requirements (e.g., Grade II professional contracting qualification for building curtain wall engineering); 4. Participation in technical standards and patent authorization dates. For questionable certificates, you can contact the issuing authority directly for official verification. Qinglong Group has always upheld the values of "honesty and striving," and all qualification documents can be cross-verified by customers through official channels to ensure transparent cooperation.
