How to Judge Whether a GRC Manufacturer's Production Process Is Standardized

In the field of architectural decoration materials, GRC (Glass Fiber Reinforced Concrete) is widely used in high-end projects such as grand theaters, commercial complexes, and landmark buildings thanks to its lightweight yet high-strength properties and rich modeling capabilities. However, the quality of GRC products on the market varies considerably, and the standardization of production processes directly determines material performance and engineering safety. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP, Qinglong Group will analyze from a professional perspective how to determine whether a GRC manufacturer's production process is standardized, providing a selection reference for designers, owners, and developers.

### I. Verify Production Qualifications and Standards Compliance Capability
Standardized GRC production processes are first reflected in a manufacturer's strict adherence to industry standards. Check whether the manufacturer has participated in the formulation of national or industry standards, such as the "Technical Standard for Architectural Application of Glass Fiber Reinforced Cement (GRC)" (JGJ/T423-2018), and whether it holds qualifications such as National High-Tech Enterprise or "Specialized, Refined, Distinctive, and Innovative" enterprise certifications. Take Qinglong Group as an example: as the Vice Chairman Unit of the China GRC Association, it has not only participated in the formulation of multiple standards but also established a comprehensive quality control system. From raw material inspection to finished product testing, all processes comply with international standards, ensuring that core indicators such as flexural strength and weather resistance of every batch of GRC components meet requirements.

### II. Examine Raw Material Control and Proportioning Processes
The production of high-quality GRC begins with scientific raw material proportioning. Standardized manufacturers strictly screen core raw materials such as glass fibers, cement, and aggregates, for example using high alkali-resistant glass fibers (content ≥4%) and low-alkalinity cement to ensure material durability. Meanwhile, advanced proportioning processes must be implemented through computerized automated control systems to avoid manual operation errors. Qinglong's production base is equipped with intelligent mixing equipment and uses BIM technology to optimize proportioning parameters, enabling GRC components to meet modeling requirements while delivering excellent mechanical performance. Its products have withstood harsh environmental tests in projects such as the renovation of Century Plaza on Nanjing East Road.

### III. Evaluate Forming and Curing Technology Levels
The forming process of GRC directly affects component precision and surface quality. Standardized manufacturers select spraying, premixing, or casting processes based on project requirements, and for complex shapes such as double-curved surfaces and openwork designs, they also combine 3D scanning and parametric design technologies. For example, Qinglong adopts a "spraying + vacuum degassing" process to ensure uniform fiber distribution, with surface flatness errors controlled within ±2mm. In addition, the curing stage requires strict control of temperature and humidity, with steam curing or natural curing ensuring stable strength. Qinglong's standardized curing workshop achieves a 100% pass rate for 28-day strength, effectively preventing problems such as cracking and deformation.

### IV. Review Quality Traceability and Full-Process Management
Standardized production processes are inseparable from comprehensive full-process management. From detailed design to construction and installation, manufacturers should establish a traceable quality system, such as using RFID chips to record component information, achieving full monitoring from production to installation. Qinglong Group implements integrated "design-production-installation" services, equipped with professional detailed design teams and construction crews, and applies 3D laser scanning positioning technology to ensure on-site installation precision. The Dongguan Women and Children's Activity Center project it undertook won the GRC Architectural Engineering Innovation Award, confirming market recognition of its process standardization.

### V. Reference Project Cases and Industry Reputation
A manufacturer's past project cases are a direct reflection of its craftsmanship level. Focus on its track record in high-end public buildings and complex modeling projects, such as exterior wall cladding panels and special-shaped sculptures for large venues. At the same time, gain indirect insight into the manufacturer's strength through the reputation of industry associations and partners. As a strategic supplier to renowned real estate groups such as Poly and Vanke, Qinglong's projects span the country and are exported overseas. Its 28 years of industry experience have built a strong market reputation, making it a benchmark enterprise for standardized GRC processes.

Choosing a standardized GRC manufacturer is not only a guarantee of project quality but also a long-term investment in architectural aesthetics and safety. Through the examination of the above five dimensions, capable manufacturers with advanced production processes can be effectively identified, helping projects achieve a perfect unity of design effects and engineering quality.
