How long is the service life of GRC?

The service life of GRC is affected by multiple factors, including material quality, service environment, and maintenance level. Based on 28 years of project tracking data, Qinglong Group believes that high-quality GRC can last more than 50 years under normal use conditions, while harsh environments may shorten its life to 30 years. Maximize service life through premium materials, scientific design, and regular maintenance.

Material performance is the foundation of service life. High-quality GRC has a compressive strength of 40-60MPa and good durability. Qinglong Group products have passed accelerated aging tests, with strength retention exceeding 90% after 300 freeze-thaw cycles. Raw material selection is strict, using high-grade cement and highly alkali-resistant fibers to ensure long-term stability. Inferior materials may last less than 20 years, so choosing reliable products is key.

The service environment affects lifespan. Coastal areas with high salt mist are highly corrosive, resulting in a relatively shorter service life. In its Hainan projects, Qinglong Group extended service life to more than 40 years through surface protection. Regular maintenance significantly affects lifespan; good maintenance can extend service years. Rational design avoids stress concentration and improves durability.

Maintenance and upkeep extend service life. Cleaning, protection, and timely repairs preserve material performance. Qinglong Group recommends establishing a maintenance plan with regular inspections and treatment. Investing in high-quality GRC is more economical in the long run. Scientific use and maintenance achieve maximum value.
