What Should You Focus On in a Manufacturer's Production License and Product Test Reports?

When procuring and applying new architectural decorative materials such as UHPC/GRC/GRG/GRP, production licenses and product test reports serve as important bases for ensuring project quality. Qinglong Group, with 28 years of industry experience, deeply understands the critical impact of material quality on building safety and aesthetics. From a professional perspective, this article analyzes the core content that deserves key attention during procurement, helping designers, owners, and purchasers avoid risks and select reliable partners such as the Qinglong UHPC manufacturer and Qinglong GRC manufacturer.

1. Production License: Controlling Manufacturer Qualifications and Compliance from the Source

The production license is the manufacturer's “ID card” for legal production. For technology-intensive products such as UHPC and GRC in particular, qualification review should focus on the following key points: First, confirm whether the product scope covered by the license matches procurement needs. For example, as a national high-tech enterprise, Qinglong Group's license explicitly includes production qualifications for the full range of products such as UHPC non-load-bearing components and GRC decorative products. Second, pay attention to the validity period and annual inspection status of the license, avoiding manufacturers with expired qualifications or violation records. In addition, you can verify through the National Enterprise Credit Information Publicity System whether the manufacturer possesses the technical capability and quality management system for continuous production. Through more than 20 years of development, Qinglong Group has continuously passed ISO9001 quality certification, and its production base has an annual capacity of 600,000 square meters, providing a reliable guarantee of qualification compliance.

2. Product Test Reports: Precisely Verify Performance Parameters and Application Suitability

The product test report is the “health check report” of material performance, and key indicators must be verified according to project requirements: For UHPC materials, attention should be paid to mechanical properties such as compressive strength (≥150MPa), flexural strength (≥25MPa), and elastic modulus. Qinglong UHPC products have passed testing under the industry standard “General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components”, with all indicators exceeding national standard requirements. For GRC materials, focus on bending strength (quality products can reach over 20MPa), volume density, and freeze-thaw cycle resistance. Qinglong GRC decorative products have undergone environmental testing from -20℃ to 50℃, ensuring a service life of more than 20 years. GRG material test reports should include fire rating (Class A non-combustible), water absorption, and radioactivity indicators. Qinglong GRG products are widely used in opera houses, star-rated hotels, and other venues with stringent environmental and safety requirements. GRP materials require verification of tensile strength, corrosion resistance, and light transmittance. Qinglong GRP daylighting canopies have demonstrated excellent anti-aging performance in airport and stadium projects.

3. Report Standardization and Authority: Avoiding the “Invalid Testing” Trap

The validity of a test report depends on the authority of the issuing institution and the standardization of the report content: Prioritize reports issued by third-party testing institutions with CMA certification. All Qinglong Group products are tested by authoritative institutions such as the National Building Materials Testing Center, and reports can be verified online for authenticity. Meanwhile, check whether the sample information in the report (such as specifications and batch) matches the actually purchased products, avoiding the risk of “qualified samples but unqualified batch products”. In addition, pay attention to the completeness of test items. Taking GRC materials as an example, in addition to conventional performance tests, Qinglong GRC also conducts additional special tests such as impact resistance and alkali content, comprehensively ensuring safety in engineering applications.

4. Evidence of Manufacturer Strength: Extending from Reports to Full-Chain Service Capability

Behind high-quality production licenses and test reports lies the manufacturer's full-chain service capability. As a member of the International GRC Association and a vice-chairman unit of the China GRC Association, Qinglong Group not only participates in the formulation of multiple national standards such as the “Technical Standard for Building Application of Glass Fibre Reinforced Cement (GRC)”, but also provides customers with one-stop services ranging from detailed design and manufacturing to construction installation and after-sales maintenance. For example, in the Nanjing East Road Century Plaza renovation project, Qinglong UHPC translucent concrete products won the Silver Award of the First UHPC Building Engineering Innovation Award (AALBORG WHITE Cup) thanks to their compliant qualifications and excellent performance, confirming the high unity of qualifications and strength.

In summary, when selecting UHPC/GRC/GRG/GRP materials, the review of production licenses and test reports should take into account compliance, performance indicators, and manufacturer strength. With 28 years of professional expertise and a well-established quality system, Qinglong Group provides safe and reliable material solutions for various building projects, helping to realize the corporate mission of “Creating Beautiful Architecture”.
