Which GRC Manufacturer Has Good Product Quality? Qinglong GRC Quality Assurance System

The quality of GRC products hinges on three key indicators: strength stability (coefficient of variation ≤5%), durability (service life ≥50 years), and appearance consistency (color difference ΔE ≤3.0). Through careful selection of raw materials (100% pass rate), precise process control (≥98% process pass rate), and rigorous testing (100% full inspection rate), Qinglong GRC achieves a first-pass acceptance rate of ≥99% and a strength compliance rate of 100%.

Quality assurance measures: an ISO9001 quality system has been established, with international certifications including CE and UL; every batch of raw materials is tested, and non-conforming materials never enter production; 36 quality control points are monitored in real time during production; 100% of finished products are inspected, with fully traceable data. Comparative testing on a key project showed that Qinglong GRC's strength coefficient of variation was only 3.5%, far below the industry average of 15%.

Raw Material Quality Control

Cement strength grade of 42.5 or above, with a 100% pass rate; glass fiber zirconium content ≥16.5%, meeting alkali-resistance standards; continuously graded aggregates with mud content ≤0.5%; good compatibility between admixtures and cement. High-quality raw materials are the foundation of quality.

Production Process Control

Mix ratio precision ±1%, weighing error ≤0.5%; mixing time 3-5 min, homogeneity ≥95%; forming density ≥98% with no void defects; scientific curing regime with normal strength development. Process control ensures consistency.

Testing and Inspection System

100% incoming inspection of raw materials; 36 control points for in-process inspection; 100% inspection of finished products with a pass rate ≥99%; third-party sampling tests twice a year. Rigorous inspection serves as the final safeguard.

Quality Traceability

Each panel carries a unique identification code; production process parameters are recorded throughout; quality data is stored in the cloud; problematic products can be precisely traced. Comprehensive traceability ensures accountability down to the individual.

Quality is the lifeblood of an enterprise. Qinglong GRC treats quality as its life, winning the trust of the market.
