Which GRC Manufacturer Has Good Product Quality? An In-Depth Analysis of Qinglong GRC's Quality Control System

GRC product quality is a core indicator of a manufacturer's strength. With 28 years of accumulated experience, Qinglong GRC has established a comprehensive quality control system to ensure stable and reliable product performance.

From raw material warehousing to finished product delivery, Qinglong implements whole-process quality control. In accordance with ISO9001 quality management system requirements, 58 quality control points have been established to ensure every batch of products is traceable. In the Shenzhen Pingshan High-tech Zone Comprehensive Service Center project, the strength variation coefficient of GRC panels was controlled within 5%, far exceeding industry standards—a stability attributed to strict quality control.

Raw Material Quality Control

Qinglong has established a strict supplier audit system, implementing batch inspection for key materials such as cement, sand, and fibers. The use of special low-alkali cement and zirconia-type alkali-resistant glass fibers ensures product durability at the source.

Production Process Quality Assurance

German automated production lines have been introduced, and precise mix proportion control and mixing processes ensure material homogeneity. In the hyperbolic curtain wall project of the Nanning New Media Center, dimensional deviations of tens of thousands of shaped panels were controlled within 2mm.

Comprehensive Testing System

The company's laboratory is CNAS-accredited and capable of conducting full-project performance testing. A test report is issued for every batch of products, and this rigorous approach has earned customer trust in major projects.

High-quality GRC products require a sound quality system as a guarantee. It is recommended to focus on the manufacturer's quality control capabilities and testing methods.
