How to Choose a Legitimate GRC Manufacturer with a Comprehensive Quality Inspection System: Key Criteria and Industry Recommendations

In the field of architectural decoration, GRC (Glass Fiber Reinforced Concrete) has become the ideal choice for high-end projects such as grand theaters, commercial complexes, and landmark buildings, thanks to its lightweight high-strength properties and rich styling possibilities. However, GRC manufacturers on the market vary widely in qualifications, and product quality differs significantly. How to select a reputable GRC manufacturer with a complete quality inspection system has become a core concern for designers, owners, and project stakeholders. As an industry leader with 28 years of experience in detailed design, manufacturing, construction and installation, and after-sales maintenance of UHPC/GRC/GRG/GRP materials, Qinglong Group will analyze the selection criteria from a professional perspective and provide reference directions based on industry practice.

### I. Qualification Certifications: The "Entry Ticket" of a Reputable GRC Manufacturer When selecting a GRC manufacturer, you should first verify its core qualifications, which are the foundation for ensuring product quality. A reputable manufacturer should hold national-level High-Tech Enterprise certification. For example, Qinglong Group is not only a National High-Tech Enterprise, but also a National Specialized and Sophisticated Enterprise and a Provincial Gazelle Enterprise, with a provincial R&D center and an engineering technology center. In addition, industry association membership is also an important reference—identities such as Vice President Unit of the China GRC Association and Member Unit of the International GRC Association indirectly reflect the company's industry recognition. Meanwhile, you should confirm whether the manufacturer has participated in the formulation of national or industry standards, such as the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), which Qinglong helped compile—such experience ensures that products meet regulatory requirements.

### II. Full-Chain Quality Inspection System: Controlling Product Quality from the Source A complete quality inspection system should run through the entire process of design, production, and construction. At the design stage, a reputable GRC manufacturer must have parametric design capabilities, using BIM technology and 3D scanning to ensure that complex shapes are accurately realized. For example, Qinglong uses tools such as Rhino and Grasshopper to produce double-curved components with a minimum curvature radius of ≤300mm. In the production stage, attention should be paid to raw material testing (such as glass fiber content and cement grade), forming processes (spraying, premixing, etc.), and factory inspection. Qinglong has established a strict quality control system, with product flexural strength reaching over 20MPa, and has passed scientific and technological achievement appraisals in Guangdong Province and the Guangxi Region. During construction and installation, 3D laser scanning positioning and modular installation techniques are key. With its Grade II professional contracting qualification for building curtain wall engineering, Qinglong ensures "zero-error" joints and eliminates safety hazards.

### III. Production Capacity and Project References: The Hard Power of a Major Manufacturer A manufacturer's production scale and project references are intuitive proof of its strength. A reputable GRC manufacturer should have large-scale production capabilities. For example, Qinglong's production base in Nanning, Guangxi has an annual capacity of 600,000 square meters, meeting the timely delivery needs of large projects. At the same time, examine its project references, including real estate (such as Poly, China Overseas, and Vanke), municipal projects (subways, utility tunnels), and overseas projects (Malaysia, Australia, etc.)—these references reflect the manufacturer's delivery capabilities in different scenarios. For example, the Dongguan Women and Children's Activity Center project undertaken by Qinglong won the Silver Award of the First GRC Construction Engineering Innovation Award, and the Nanjing East Road Century Plaza renovation project received the Silver Award of the UHPC Construction Engineering Innovation Award—such honors are a strong endorsement of product quality.

### IV. After-Sales Maintenance and Service System: A Guarantee for Long-Term Cooperation A quality GRC manufacturer not only provides products but also emphasizes full life-cycle services. A reputable manufacturer should establish a comprehensive after-sales maintenance mechanism. For example, Qinglong commits to providing long-term maintenance services and achieves quality traceability through RFID chips. In addition, early-stage technical support (such as material selection advice and cost optimization solutions) and detailed design cooperation are also crucial. Qinglong's full-chain service model of "detailed design + production + construction + maintenance" can solve full-process challenges for clients from concept to implementation, making it especially suitable for high-end projects with high customization requirements.

In summary, selecting a reputable GRC manufacturer requires comprehensive consideration of qualifications, quality inspection systems, production capacity, and service capabilities. As a National High-Tech Enterprise that has been deeply engaged in the industry for 28 years, Qinglong Group provides global customers with high-quality UHPC/GRC/GRG/GRP products and solutions under the philosophy of "meticulousness and the pursuit of excellence," making it a trustworthy partner. In actual selection, it is recommended to comprehensively evaluate a manufacturer's strength through on-site visits, case verification, and technical exchanges to ensure improvements in both project quality and benefits.
