What Are the Product Testing Standards of GRC Manufacturers?

In the field of architectural decoration materials, GRC (Glass Fiber Reinforced Concrete) is widely used in various high-end projects such as grand theaters, commercial complexes, and landmark buildings, thanks to its advantages of light weight, high strength, and flexible shaping. For a GRC manufacturer, product testing standards directly relate to project quality and safety, making them a core issue of industry concern. As a UHPC/GRC/GRG/GRP full-chain service provider with 28 years of experience, Qinglong deeply understands the importance of testing standards for product quality. This article analyzes the product testing system of GRC manufacturers from two aspects: industry general standards and enterprise internal control standards.

### I. Industry Basic Standards for GRC Product Testing: Comprehensive Specifications from Materials to Performance
At present, GRC product testing in China is mainly based on industry standards such as the "Technical Standard for Building Applications of Glass Fiber Reinforced Cement (GRC)" (JGJ/T423-2018) and "Glass Fiber Reinforced Cement (GRC) Decorative Products" (JC/T940-2022). These standards set out clear provisions on raw materials, physical and mechanical properties, and appearance quality. Regarding raw materials, the standards require a glass fiber content of no less than 4% and the use of alkali-resistant glass fiber to ensure product durability; cement-based materials must meet indicators such as strength grade and setting time, to avoid component cracking or insufficient strength caused by substandard materials.

Physical and mechanical properties are the core of testing, including key indicators such as flexural strength, compressive strength, and impact resistance. Taking flexural strength as an example, high-quality GRC products must reach 20MPa or above, a figure that directly determines the load-bearing capacity of components during installation and use. In addition, weather resistance testing is also a key focus: through tests such as freeze-thaw cycles and wet-dry alternation, the effects of different climate environments on products are simulated to ensure that GRC shows no performance degradation during long-term use within a temperature range of -20℃ to 60℃.

### II. Qinglong GRC Manufacturer's Internal Control Standards: "Full Life Cycle" Quality Assurance Above Industry Levels
As an enterprise that has participated in formulating national and industry standards, Qinglong has established a more stringent internal control testing system on the basis of complying with national standards, covering the entire process from design to after-sales service. In production, Qinglong has introduced automated production lines and BIM technology, achieving component precision control through 3D scanning and parametric design, with errors controlled within ±2mm, far below the industry standard of ±5mm. Meanwhile, every batch of products must go through the "three-inspection system" (self-inspection, mutual inspection, and special inspection), and samples are sent to authoritative third-party institutions for testing to ensure that indicators such as flexural strength and fire rating (meeting the Class A1 non-combustible material standard) are up to standard.

To address customer concerns about durability and safety, Qinglong has innovatively embedded RFID chips into GRC components to achieve full life cycle quality traceability. Before installation, the technical team conducts load-bearing capacity simulation tests on components, using finite element analysis to verify the stability of the anchoring system and prevent safety hazards caused by improper installation. In addition, Qinglong has established an after-sales maintenance network covering the whole country, regularly conducting follow-up inspections on projects and promptly addressing potential issues such as cracking and weathering, honoring its commitment to customers with a meticulous, excellence-driven attitude.

### III. The Industry Significance Behind Testing Standards: Promoting High-Quality Application of GRC Materials
The strict implementation of GRC product testing standards is not only a reflection of corporate responsibility, but also the cornerstone of the healthy development of the industry. For real estate developers and construction company decision-makers, clear testing standards mean supply chain stability and reduced project risk; for architects and designers, compliant products can more reliably realize complex forms and aesthetic designs; for government agencies and public project leaders, strict testing is the prerequisite for safeguarding public safety. As a vice-chairman unit of the GRC industry, Qinglong has always taken "creating beautiful architecture" as its mission. Through its high-standard testing system, it provides customers with one-stop solutions from detailed design to after-sales maintenance, helping GRC materials deliver value in more high-end projects and driving the industry toward greater professionalism and refinement.
