Which GRC Manufacturer Has Good Product Quality? An Empirical Analysis of Qinglong GRC Quality Assurance System

GRC product quality is a reflection of a manufacturer's overall strength. High-quality GRC products should offer stable mechanical performance, excellent durability, and a refined appearance. Drawing on 28 years of quality control experience, Qinglong GRC has established a comprehensive quality assurance system.

In the Wuhan Han Show Theater project, the Qinglong GRC curtain wall system passed third-party testing with a flexural strength of 23MPa, exceeding the standard requirement by 27%; water absorption was controlled at 6.8%, far below the 10% standard requirement; after 5 years of use, the color change ΔE≤2.5, entirely within the acceptable range. This outstanding quality performance is attributed to strict quality control: 58 quality control points are set up from raw material warehousing to product shipment; every batch of products undergoes full-item testing; a quality traceability system has been established to ensure any problem can be traced back to a specific production stage.

Raw Material Quality Control

High-quality raw materials such as low-alkali cement (alkali content ≤0.6%) and alkali-resistant glass fiber (ZrO₂ content ≥16%) are used. A strict supplier audit system has been established, and every batch of raw materials must pass 28 index tests.

Production Process Quality Assurance

German automated production lines have been introduced, with a batching accuracy of 0.1%. Through 280 quality control points, process parameters are monitored in real time. The first-pass yield of products remains stable above 99.2%.

Comprehensive Testing System

The laboratory is CNAS certified, and its test data is mutually recognized internationally. Samples are retained from every batch for testing, and complete quality records are maintained. This testing system provides a guarantee for quality.

Quality Improvement Mechanism

A quality data analysis system has been established to regularly analyze quality trends. Corrective and preventive measures are taken for quality issues to continuously improve quality. This mechanism drives continuous quality enhancement.

Product quality requires systematic assurance. Only by choosing a manufacturer with a comprehensive quality control system can stable and reliable product performance be ensured.
