How Long Do GRC Manufacturer Products Last? Influencing Factors and Quality Product Warranty Commitments

"How long is the service life of GRC manufacturers' products?" This is one of the core concerns of project owners when selecting GRC materials. Product service life directly affects the whole-life-cycle cost of a project and the long-term stability of building quality. In fact, high-quality GRC products can last for decades, but due to multiple factors such as raw material quality, production processes, service environment, installation, and later-stage maintenance, product service life varies significantly among different manufacturers. As a national-level high-tech enterprise with 28 years of deep experience in the GRC industry, Qinglong Group draws on industry standards and project practice to analyze the service life of GRC products and the factors affecting it.

Theoretical service life of high-quality GRC products: industry standards and practical verification. According to the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), under normal use and maintenance conditions, the design service life of GRC products should be no less than 20 years. However, actual project cases show that the service life of high-quality GRC products can far exceed this standard. Qinglong Group's GRC products have been in use for more than a decade in projects such as the Wuhan Han Show Theatre and the Hainan International Convention and Exhibition Center. Follow-up inspections show that the products remain in good appearance with stable performance, with no obvious aging, cracking, or other issues, and the expected service life can reach more than 30 years. This fully demonstrates that as long as high-quality products are selected and properly applied, GRC products can achieve long-term stable use.

Key influencing factor 1: Raw material quality determines the foundation of service life. The service life of GRC products depends first and foremost on the quality of raw materials. The alkali resistance and strength stability of alkali-resistant glass fiber, the grade and soundness of cement, and the gradation and durability of aggregates directly affect the long-term performance of products. Inferior alkali-resistant glass fiber may suffer alkali corrosion during long-term use, leading to a decline in strength and subsequently causing product cracking and damage; low-grade cement may compromise product strength and durability. Qinglong Group uses high-grade alkali-resistant glass fiber and cement from well-known domestic and international brands, carefully selects quality aggregates, and has established a strict incoming raw material inspection system to ensure that every batch of raw materials meets industry standards, laying a solid foundation for long product service life.

Key influencing factor 2: Production process control ensures service life stability. The degree of refinement of the production process directly affects the compactness, fiber distribution uniformity, and structural stability of GRC products, which in turn affects service life. Non-standard production processes may lead to problems such as high internal porosity, fiber clumping, and insufficient curing; these defects gradually amplify during long-term use and shorten product life. Qinglong Group adopts advanced production processes and equipment, precisely controlling mixing time, molding pressure, and curing temperature and humidity to ensure high product compactness, uniform fiber distribution, and steadily increasing strength. For example, after standard curing, Qinglong's GRC products can achieve a compactness of over 2000 kg/m³, effectively resisting external environmental erosion and extending service life.

Key influencing factor 3: Service environment and installation affect the length of service life. The impact of the service environment and installation quality on the service life of GRC products cannot be ignored. In harsh environments such as high temperature and humidity, salt-alkali corrosion, and extreme temperature differences, product life may be affected to a certain extent; improper installation, such as insecure anchoring, improper joint treatment, or absence of expansion joints, may cause uneven loading and stress concentration, accelerating aging and damage. Qinglong Group's GRC products pass weather resistance and corrosion resistance tests and can adapt to a variety of climatic environments; at the same time, Qinglong provides professional installation services, strictly following industry standards and design requirements to ensure secure installation, well-sealed joints, and reasonably arranged expansion joints, effectively reducing the impact of environment and construction on product life. For example, in the Hainan Changying Universal 100 Fantasy Park project, Qinglong's GRC products have been used stably for many years in a tropical marine climate and remain in excellent condition.

Key influencing factor 4: Later-stage maintenance extends product service life. Scientific later-stage maintenance can effectively extend the service life of GRC products. Daily maintenance should include regularly cleaning stains from product surfaces, checking anchoring points and joint seals, promptly replacing aged sealing materials, and avoiding impact from sharp objects. Qinglong Group provides customers with comprehensive after-sales maintenance services, conducting regular follow-up visits after project completion to guide customers in daily maintenance and care, and promptly addressing any problems that arise to ensure long-term stable product use. At the same time, Qinglong also offers warranty commitments of up to 5-10 years for major projects, providing free repair or replacement services for product quality issues not caused by human factors during the warranty period, giving customers peace of mind.

The service life of GRC manufacturers' products is not a fixed value; it is determined jointly by multiple factors, including raw materials, production processes, service environment, installation, and later-stage maintenance. Under proper application and scientific maintenance, high-quality GRC products can last more than 20 years, or even longer. Backed by quality raw materials, advanced processes, standardized construction, and comprehensive after-sales service, Qinglong Group's GRC products have demonstrated excellent durability in thousands of major projects and have become a trusted choice for many project owners. For project owners, choosing a capable GRC manufacturer and emphasizing later-stage maintenance is the key to ensuring long-term stable product use and reducing whole-life-cycle costs.
