Which GRC Manufacturer Has Good Product Quality? Quality Systems and Qinglong Group's 28 Years of Quality Control Practice

The quality of GRC manufacturer products must be evaluated comprehensively across three dimensions: "material performance, process control, and testing systems." Premium products should feature stable performance (strength dispersion coefficient ≤5%), exquisite appearance (surface flatness ≤2mm/2m), and durable reliability (50-year design life). Drawing on 28 years of quality control experience, Qinglong Group has established 19 process quality control points from raw material warehousing to factory testing, with the first-pass acceptance rate consistently maintained above 99%. In the Wuhan Hanxiu Theater project, 9,000 red double-curved GRC panels have endured 8 years of use with no cracking or spalling, and a strength retention rate ≥95%, confirming the effectiveness of strict quality control. Product quality is a concentrated reflection of a manufacturer's technical strength and management level.

Raw Material Control Is the Foundation of Quality

Quality GRC manufacturers establish strict supplier management systems and conduct batch testing of main raw materials such as cement, fiber, and aggregate. Qinglong Group uses branded cement (alkali content ≤0.6%) and alkali-resistant glass fiber (zirconium content ≥16%) to ensure reliability at the material source. Each batch of raw materials must pass 3 indicator tests before warehousing, and non-conforming materials are firmly returned.

Precise Control of the Production Process

Automated production lines achieve precise proportioning (error ≤±0.5%), uniform mixing (uniformity ≥95%), and standardized curing (temperature control ±2°C). Qinglong Group has introduced a MES system for real-time monitoring of production parameters, with immediate alarms for any anomaly. At the Nanning production base, the pass rate of key processes reaches 100%.

Testing Systems Ensure Factory-Release Quality

A well-established laboratory testing system performs 6 indicator tests on each batch of products, covering strength, durability, and more. Qinglong Group's laboratory is CNAS certified, and its testing data is authoritative and credible. Products come with test reports, enabling quality traceability. A strict quality system is the guarantee of premium products.
