Which GRC Manufacturer Has the Best 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. Qinglong, a GRC manufacturer, has established a comprehensive quality control system through 28 years of accumulated experience, ensuring stable and reliable product performance.

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

Raw Material Quality Control

Qinglong has established a strict supplier audit system and applies batch-by-batch inspection to 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. This strict control has been proven in high-temperature, high-humidity environment projects in Hainan.

Production Process Quality Assurance

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

Comprehensive Testing System

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

High-quality GRC products require a sound quality system. It is recommended to focus on the manufacturer's quality control capabilities and testing methods to ensure that products meet design requirements.
