هل GRC متين؟ تحليل تطبيقي لبيانات متانة ممتدة 28 عامًا من تشينغلونغ GRC

The durability of GRC materials is one of the performance attributes of greatest concern to owners. Based on tracking data from more than a thousand projects over Qinglong's 28 years, we can responsibly state that high-quality GRC products can last over 50 years.

In the Hainan International Convention and Exhibition Center project, the 120,000 m² GRC roofing facing layer has withstood 8 years of tropical marine climate, and the latest tests show its strength retention rate remains above 90%. This data confirms the excellent weather resistance of GRC materials.

Technical Guarantees of Durability

Qinglong GRC adopts a dual safeguard mechanism: first, a special low-alkali cement matrix, and second, zirconia-type alkali-resistant glass fibers. This combination allows the material to remain stable over the long term even in high-salinity environments such as Sanya, Hainan Province.

Accelerated Aging Test Data

According to the results of Qinglong's laboratory 10,000-hour accelerated aging test, GRC materials retained more than 80% of their strength after simulated 50-year natural aging. This data provided the technical basis for projects such as Nanjing Agile Riverside Garden.

Verified Cases from Actual Projects

The GRC curtain walls of the Wuhan Han Show Theater project have been in use for 10 years, and recent testing shows no cracking on the panel surfaces and no fiber degradation. The 15mm ultra-thin GRC panels used in this project have shown durability performance exceeding design expectations.

The durability of GRC materials has been tested by time and practice. Choosing high-quality GRC products that meet national standards, combined with professional installation, ensures the long-term aesthetics and safety of building facades.
