Which GRC Manufacturer Has Good Product Quality? — An In-Depth Analysis of the Quality Indicator System

Quality evaluation of GRC products requires a scientific indicator system covering multiple dimensions, including physical performance, durability, and appearance quality. Based on 28 years of quality control experience, Qinglong Group believes that premium GRC products should simultaneously meet strength standards (flexural strength ≥18MPa), durability requirements (mass loss ≤5% after 300 freeze-thaw cycles), and appearance specifications (flatness ≤3mm/2m).

Raw material control is the foundation of quality. Qinglong Group tests every batch of incoming raw materials: cement strength grade no lower than 42.5, and fiber zirconium content ≥16%. Mix proportions are optimized through extensive testing to ensure optimal performance. The production process is strictly monitored, with quality control points established at critical procedures. These measures safeguard quality at the source.

Testing systems verify quality levels. Qinglong Group's laboratory has comprehensive testing capabilities, conducting strength and durability tests on every batch of products. Samples are regularly sent to third-party testing agencies to ensure objective and impartial data. Through rigorous testing, the product pass rate has consistently remained above 99.5%.

Project validation is the final test. Qinglong GRC has withstood the test in multiple major projects, such as the Hainan International Convention and Exhibition Center, which has performed well over 5 years of use. These practices have verified the reliability of product quality. Owners are advised to require manufacturers to provide complete test reports and project references when making their selection.
