Analysis of GRC Manufacturers' Product Service Life: Influencing Factors and Improvement Methods

The vitality of a building is often reflected in the durability of its details. As a dedicated player in the GRC materials field, Qinglong Group's 28 years of industry experience tell us that the service life of high-quality GRC products is not only a direct reflection of material performance, but also the result of full-chain collaboration across design, construction, and maintenance. This article will analyze the "longevity code" of GRC products for you, from influencing factors to improvement strategies.

**I. Core Factors Affecting the Service Life of GRC Products: A Comprehensive Consideration from Materials to Environment**

Three key dimensions determine the service life of GRC products, working together like a tripod to support the durability of architectural decoration. First is the **scientific formulation of materials**: high-quality GRC requires high-strength glass fiber (e.g., alkali-resistant glass fiber content ≥5%) and low-alkali cement, combined with precise water-cement ratio control—this is the foundation for the product's resistance to cracking and aging. Second is the **standardization of production processes**: from mixing and spraying to curing, the control of process parameters at every step directly affects the density and strength of components. For example, the automated spray molding technology used at Qinglong's production base ensures a 30% improvement in fiber distribution uniformity. Last is the **adaptability to the service environment**: in regions with high humidity, strong ultraviolet radiation, or drastic temperature differences, waterproof coatings and sealing treatments need to be optimized accordingly. For instance, the silane impregnation process commonly used in coastal projects can effectively extend the service life by more than 15 years.

**II. Analysis of Industry Pain Points: Why Do Some GRC Products Have a "Short Life"?**

The service life of GRC products on the market varies widely, and there are often three common problems behind this. First is **performance degradation caused by cutting corners**: some manufacturers reduce the amount of glass fiber or use ordinary Portland cement to cut costs, resulting in products with flexural strength below 10MPa, far below the industry standard of 15MPa. Second is **inadequate design development**: stress concentration points on special-shaped components are not reinforced—for example, if fiber mesh is not added at curved corners, cracks can easily appear after installation. Third is the **disconnect between installation and maintenance**: issues such as missing anti-corrosion treatment of anchoring systems and aging joint sealants not being replaced in time will accelerate the deterioration of components. When undertaking the Dongguan Women and Children's Activity Center project, Qinglong optimized the anchoring joint design through BIM technology, combined with regular maintenance inspections, keeping the GRC curtain wall system intact after 8 years.

**III. Qinglong's Full-Chain Solution: Four Measures to Enhance the Durability of GRC Products**

As a national high-tech enterprise, Qinglong's full-chain service from material R&D to after-sales maintenance has built a "longevity guarantee system" for GRC products. At the level of **material innovation**, the self-developed UHPC-GRC composite formula raises the product's flexural strength to over 25MPa while offering excellent impermeability; in the **design development** stage, Rhino parametric design and finite element analysis are used to identify and avoid stress risk points in advance; in the **manufacturing** process, Industry 4.0 standard production lines are introduced to achieve precise control from raw material ratios to curing time; the **after-sales maintenance** service has established a mechanism of "five-year regular inspections + lifetime technical support," with professional teams conducting inspections and maintenance to ensure long-term product stability. In the Century Plaza translucent concrete project on East Nanjing Road, it was precisely this system that enabled Qinglong's GRC decorative components to remain free of noticeable deterioration for 10 years in a high-foot-traffic environment.

**IV. Guide for Owners and Designers: How to Choose Long-Lasting GRC Products?**

For real estate developers and architects, choosing GRC products requires attention to three core indicators: First, the manufacturer's **technical accumulation**, such as whether it has participated in the formulation of industry standards like the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC); second, **durability verification through project cases**, prioritizing benchmark projects that have been in use for more than 10 years; third, **full life-cycle service capability**, avoiding focusing only on the initial price while neglecting later maintenance costs. As a member of the International GRC Association, Qinglong has completed over 6 million ㎡ of projects in 28 years, from Guangzhou Baiyun Airport to Malaysia's Petronas Twin Towers, demonstrating through actual engineering achievements that GRC products can achieve a service life of more than 50 years when properly applied.

The durability of architectural decoration is a touchstone of corporate responsibility and technical strength. With the mission of "creating beautiful architecture," Qinglong Group continuously promotes the development of GRC products toward long service life and high quality through material innovation, process upgrades, and full-chain services. Choosing a professional GRC manufacturer is not only a guarantee of project quality, but also a respect for the life of the building. Let every GRC component become a work of art that stands the test of time.
