How to Check GRC Manufacturer Qualifications: Detailed Steps and Key Considerations

In the field of architectural decoration materials, GRC (Glass Fiber Reinforced Concrete), with its lightweight yet high-strength properties and rich design possibilities, is widely used in high-end projects such as grand theaters, commercial complexes, and landmark buildings. However, the quality of GRC products on the market varies considerably, making the selection of a manufacturer with compliant qualifications key to ensuring project safety and quality. As a GRC manufacturer with 28 years of industry experience, Qinglong Group will analyze how to systematically verify GRC manufacturer qualifications from a professional perspective, providing a practical guide for designers, owners, and project stakeholders.

I. Core Dimensions of GRC Manufacturer Qualification Verification: From Basic Compliance to Technical Strength

1. Production Qualifications: The Basic Threshold for Industry Entry
A legitimate GRC manufacturer must possess basic documents such as a Business License and Production License, with particular attention to whether the "business scope" explicitly includes "GRC product manufacturing." In addition, you may request the manufacturer's Pollution Discharge Permit to ensure its production process complies with environmental standards—this is a fundamental requirement that Qinglong Group, as a National High-Tech Enterprise, has always strictly observed.

2. Technical Certifications: Hard Indicators of Professional Capability
Authoritative technical certifications directly reflect a GRC manufacturer's strength. For example, the Technical Standard for Glass Fiber Reinforced Cement (GRC) Building Applications (JGJ/T423-2018), which Qinglong Group participated in drafting, and the "Outstanding Contribution Award for GRC Standard Development" it received both attest to its technical strength. It is recommended to give priority to manufacturers whose products have passed testing by CNAS-accredited laboratories and who hold qualifications such as "National High-Tech Enterprise" and "Specialized, Refined, Distinctive, and Innovative Enterprise"—such companies typically have more mature production processes and quality control systems.

3. Project Track Record: Direct Proof of Hands-On Experience
A quality GRC manufacturer should be capable of delivering large-scale projects. You may request typical case studies from the past 3-5 years, such as key contract pages and on-site photos of landmark buildings and large public construction projects. The experience Qinglong Group has accumulated in projects such as the Nanjing East Road Century Plaza renovation project and the Dongguan Women and Children's Activity Center is strong evidence of its engineering capabilities. Pay special attention to the authenticity of case studies and avoid false information such as "falsely claimed projects."

II. Practical Steps for Qualification Verification: From Document Review to Site Visits

1. Document Review: Three Looks and Three Checks to Distinguish Authenticity
• Check qualification validity periods: Ensure documents such as the Production License and Test Reports are within their validity periods to avoid using expired qualifications;
• Verify the authority of certification bodies: Test reports issued by official institutions such as the "National Building Materials Testing Center" are far more credible than those from informal organizations;
• Check key parameters: Focus on core indicators of GRC products such as flexural strength (recommended ≥15MPa) and frost resistance (≥200 freeze-thaw cycles). Qinglong Group's products achieve flexural strength above 20MPa, far exceeding the industry average.

2. Site Visits: Evaluating Production Capability Across the Entire Chain
When conditions permit, it is recommended to visit the manufacturer's production base in person. Focus on:
• Production line scale: For example, Qinglong Group's Guangxi production base has an annual capacity of 600,000 square meters, ensuring delivery efficiency for large projects;
• Process equipment: Whether automated molding equipment, 3D scanning, and BIM detailed design teams are in place directly affects the ability to realize complex shapes;
• Quality control processes: Full-process quality inspection records from raw material inspection to finished product shipment reflect the rigor of the manufacturer's quality control.

3. Reputation Verification: Cross-Checking Through Multiple Channels
Learn about the manufacturer's reputation through industry associations (such as the China GRC Association), partner evaluations, and project owner feedback. Qinglong Group, as a vice-chairman unit of the China GRC Association and a member of the International GRC Association, has long-term partnerships with well-known companies such as Poly and Vanke, which also indirectly reflects its market recognition.

III. Precautions: Avoiding Common "Pitfalls" in Qualification Verification

1. Beware of "Qualification Renting" and "False Advertising"
Some manufacturers muddle through by renting qualifications or photoshopping test reports. It is recommended to request original scanned copies of qualification documents and verify enterprise information through official channels (such as the "National Enterprise Credit Information Publicity System").

2. Distinguish Between "General Qualifications" and "Specialized Capabilities"
Not all qualifications are directly related to GRC products. Focus on specialized certifications related to the production, design, and construction of "glass fiber reinforced concrete," and avoid being misled by irrelevant qualifications.

3. Value "Full-Chain Service Qualifications"
A quality GRC manufacturer should have full-chain capabilities from detailed design to construction and installation. You may request qualifications such as "Professional Contracting for Building Curtain Wall Engineering" and "Professional Contracting for Building Decoration Engineering" to ensure seamless and professional project implementation.

When selecting a GRC manufacturer, qualification verification is the first line of defense in ensuring project quality. As a GRC manufacturer deeply rooted in the industry for 28 years, Qinglong Group has always upheld the values of "honesty, dedication, trust, and collaboration," providing customers with compliant and reliable products and services. By following the steps above, you can effectively identify GRC suppliers with genuine strength, laying a solid foundation for the safety and aesthetic realization of building projects.
