How to Judge the Quality of GRC Products? — A Practical Guide to Product Quality Evaluation

Judging the quality of GRC products requires professional evaluation methods and standards, with comprehensive assessment across multiple dimensions including appearance, performance, and durability. Qinglong Group believes that high-quality GRC products should meet aesthetic, functional, and durability requirements simultaneously, and systematic evaluation ensures the selection of truly premium products.

Appearance quality is the most intuitive basis for judgment. The surface of high-quality GRC products should be flat and smooth, free from defects such as color variation, air bubbles, and cracks. Qinglong Group controls product surface flatness within 3mm/2m and color difference ΔE≤3.0. Edges should be neat and free from chipped corners. Visual inspection and simple measurements allow a preliminary assessment of a product's appearance quality. For decorative art components, attention should also be paid to modeling accuracy and detail expression.

Performance indicators are the core criteria for judgment. Mechanical properties such as flexural strength and impact resistance need to be tested with professional equipment. Qinglong Group's GRC products achieve flexural strength ≥18MPa and impact energy ≥10J, and these figures should be verified by third-party test reports. In addition, attention should be paid to durability indicators such as frost resistance and weather resistance. Reviewing test reports provides an objective understanding of product performance levels.

Real-world application performance is an important reference. Inspecting completed projects, especially those that have been in use for some time, provides direct insight into the long-term performance of products. Projects involving Qinglong Group have withstood years of service while maintaining good performance, offering strong proof of product quality. Evaluation from multiple perspectives enables a comprehensive judgment of product quality.
