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

The quality of GRC products must be judged through a systematic evaluation framework. High-quality GRC products should feature stable mechanical performance, excellent durability, and good appearance quality. Based on 28 years of quality control experience, Qinglong GRC has established a comprehensive quality assurance system.

In terms of product quality, Qinglong GRC enforces strict corporate standards: flexural strength ≥20MPa, exceeding national standard requirements; impact strength ≥18kJ/㎡; and durability indicators verified through accelerated aging tests, achieving a service life of over 50 years. In the Shenzhen Qianhai project, third-party testing showed that the product strength coefficient of variation was controlled within 5%, with a 99.5% appearance quality pass rate. These figures demonstrate the outstanding quality of Qinglong GRC products.

Raw Material Quality Control

Premium low-alkali cement is used, with alkali content ≤0.6%; zirconia-type alkali-resistant glass fibers are used, with zirconia content ≥16.5%; and carefully selected quartz sand, with mud content ≤0.3%. These premium raw materials lay the foundation for product quality.

Production Process Quality Control

136 quality control points ensure production process stability; fully automated production lines reduce human error; and a system of first-article inspection, patrol inspection, and last-article inspection is implemented. This control ensures consistent product quality.

Comprehensive Testing Methods

The laboratory is CNAS-accredited, with test data internationally recognized; advanced testing equipment is provided, such as universal testing machines and freeze-thaw test chambers; and a batch inspection system ensures a 100% pass rate for products leaving the factory.

Quality Traceability System

A comprehensive quality traceability system has been established, with each panel bearing a unique identifier; raw materials are traceable to suppliers and production batches; and production process data is fully preserved. This system ensures that any issue can be traced.

Product quality requires systematic assurance. It is recommended to choose manufacturers with quality system certification and to request third-party test reports. With its comprehensive quality system, Qinglong GRC ensures outstanding product quality.
