What Is the Service Life of GRC Manufacturer Products? Durability and Qinglong Group's Long-Term Performance Tracking

The service life of GRC products is affected by material performance, service environment, and maintenance conditions. High-quality products have a design life of ≥50 years under normal use. Based on 28 years of project tracking data combined with accelerated aging tests, Qinglong Group has confirmed that its GRC products, in standard environments, show an annual carbonation depth increase of ≤0.1mm and an annual strength decay rate of ≤0.5%, with an actual service life of more than 70 years. In the coastal project of the Hainan International Convention and Exhibition Center, the GRC roofing system has endured 10 years of high-salt, high-humidity conditions with a performance retention rate of ≥90%. Service life is the ultimate proof of material durability.

Material Nature Determines the Foundation of Service Life

High-quality GRC has a compressive strength of ≥40MPa, an impermeability grade of ≥P12, and a chloride ion diffusion coefficient of ≤2.0×10⁻¹² m²/s. Qinglong Group significantly enhances durability by adding silica fume (20-30%) and optimizing fiber distribution. Material genes are the prerequisite for longevity.

Environmental Adaptability Extends Service Life

Specialized formulations are developed for different environments—for example, enhanced chloride ion resistance for coastal areas and improved frost resistance (≥F300) for severely cold regions. Qinglong products have been verified in various harsh environments and offer strong adaptability. Scientific selection maximizes service life.

Maintenance Unlocks Potential Value

Regular inspection, cleaning, and local repairs can extend service life by 20-30%. Qinglong Group provides a 10-year warranty and lifetime maintenance service. In the Nanning New Media Center project, regular maintenance keeps the products as good as new over time. Maintenance is a value enhancer for service life.

GRC products are long-life materials. Through technological innovation and refined services, Qinglong Group helps customers realize the dream of century-long buildings.
