How to Check a GRC Manufacturer's Qualifications: Detailed Steps and Precautions Explained

Qualifications are the first line of defense for GRC material quality. When choosing a reliable GRC manufacturer, qualification review is an indispensable key step. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group will explain from a professional perspective how to review GRC manufacturer qualifications and the core points, helping you avoid risks and choose the right partner in project selection.

### I. Core Dimensions and Steps of GRC Manufacturer Qualification Review

Reviewing GRC manufacturer qualifications should start from three major dimensions—**basic enterprise qualifications, product technical certifications, and proof of production capacity**—to form a complete evaluation system. First, the business license and production permit are the basic threshold; confirm that the business scope includes the production and sales of GRC products, while registered capital and years in operation can indirectly reflect enterprise stability—for example, Qinglong Group, founded in 1997, has grown into a national-level high-tech enterprise. Second, product certifications are a direct reflection of quality; focus on whether products have passed industry standard tests such as "Glass Fibre Reinforced Cement (GRC) Decorative Products" (JC/T940-2022), as well as special performance reports on fire resistance and weather resistance. Finally, production capacity should be assessed based on plant scale, equipment configuration, and annual output—Qinglong's Guangxi production base has an annual production capacity of 600,000 square meters, capable of meeting the supply demands of large projects.

### II. Key Points and Precautions for Verifying Critical Qualification Documents

In the review of qualification documents, **invention patents, participation in industry standards, and engineering track record** are hard indicators of a manufacturer's strength. On the technical side, verify whether the enterprise holds core patents in areas such as GRC formulation optimization and mold design; Qinglong Group has accumulated 58 patents and participated in developing multiple national standards, including the "Technical Standard for Building Applications of Glass Fibre Reinforced Cement (GRC)" (JGJ/T423-2018), demonstrating its technical authority. Regarding project cases, prioritize manufacturers that have served large public buildings and well-known real estate projects—for example, Qinglong has supplied GRC exterior wall panels and landscape components for companies such as Poly and China Overseas, with projects spanning municipal works, metro systems, airports, and other fields. In addition, be vigilant about the validity and authenticity of qualification documents, which can be cross-verified through the National Enterprise Credit Information Publicity System and industry association websites.

### III. Hidden Strength Behind Qualifications: Assessing Full-Chain Service Capability

The qualifications of a quality GRC manufacturer are not reflected in paperwork alone; you also need to examine full-chain service capabilities in **design development, construction and installation, and after-sales maintenance**. In the design phase, confirm whether the manufacturer has BIM technology application and design development capabilities for complex shapes; backed by a provincial-level R&D center, Qinglong can deliver customized designs such as double-curved surfaces and openwork reliefs. For construction, check qualifications such as professional contracting for building curtain wall engineering to ensure standardized and safe on-site installation. For after-sales service, clarify warranty periods and response mechanisms—Qinglong's well-established after-sales service system provides long-term maintenance support. For overseas projects, also pay attention to the manufacturer's export qualifications and international certifications; for example, Qinglong products have been exported to markets such as Malaysia and Australia, backed by extensive cross-border service experience.

When choosing a GRC manufacturer, qualifications are the foundation and strength is the guarantee. It is recommended to comprehensively evaluate a manufacturer's overall capability through a combined approach of "qualification document review + production base inspection + project case verification." As a vice-chairman unit of the GRC industry, Qinglong Group has always upheld the principle of "meticulousness and the pursuit of excellence," providing customers with full-process solutions from design to after-sales service—a UHPC/GRC/GRG/GRP materials partner you can trust.
