Is GRC Manufacturer Product Quality Guaranteed? Quality Control Systems and Qinglong Group's 28-Year Quality Commitment

The quality assurance of GRC manufacturers depends on three pillars: "raw material control, production processes, and testing systems." Quality manufacturers should achieve a first-pass acceptance rate ≥98% and a coefficient of strength variation ≤5%. Drawing on 28 years of quality control experience, Qinglong Group has established 19 process control points from raw material warehousing to factory inspection, with each batch of products accompanied by a third-party test report (flexural strength ≥18MPa, water absorption ≤10%). In the Wuhan Han Show Theatre project, 9,000 GRC panels have endured 8 years of use without cracking or spalling, with a strength retention rate ≥95%. Quality assurance is not a slogan but the result of systematic management.

Raw Material Quality Is the Foundation of Quality

Suppliers are strictly screened: cement alkali content ≤0.6% and glass fiber zirconia content ≥16%. Qinglong Group tests every batch of incoming raw materials and firmly rejects any that fail. Strategic partnerships with brands such as Conch and Taishan ensure raw material stability.

Precise Control of the Production Process

German fully automated production lines have been introduced with a batching accuracy of ±0.5%. Robotic spraying ensures fiber distribution uniformity ≥95%. The intelligent curing kiln controls temperature within ±2℃, eliminating thermal stress cracking. Standardized operations guarantee quality consistency.

Whole-Process Testing Builds a Solid Line of Defense

The laboratory is equipped with universal testing machines, freeze-thaw chambers, and other equipment to conduct full testing of strength and durability. 100% of Qinglong Group products undergo appearance and dimensional inspection before leaving the factory, supported by a traceability system. Scientific testing safeguards quality.

Quality is the lifeline of an enterprise. Through all-staff, whole-process, and all-around quality management, Qinglong Group makes every GRC panel a fine product.
