How to Judge GRC Product Quality? Qinglong GRC Manufacturer's Quality Evaluation Standards Explained

Evaluating GRC product quality requires professional knowledge and scientific methods. This article introduces how to accurately assess GRC product quality from multiple dimensions, helping you make the right judgment.

First, examine the product's appearance quality. High-quality GRC products have flat surfaces, uniform color, and neat edges and corners. A crisp sound when tapped indicates good density. Measure dimensional deviations; for qualified products, the length deviation should be controlled within ±2mm. Qinglong products use advanced production processes, achieving dimensional precision of ±1mm, far exceeding industry standards. This refined management ensures excellent appearance quality.

Strength Performance Testing

Flexural strength is a key indicator; high-quality products should be ≥18MPa. Qinglong products' measured values reach 20-25MPa, exceeding standard requirements. This high strength performance was verified in the Wuhan Han Show Theater project, where 15mm thick panels achieved curved forms spanning 8 meters.

Durability Performance Assessment

Observe the water absorption rate through an immersion test; high-quality products should have an absorption rate below 10%. Qinglong products keep it within 6%, offering better durability. In the Hainan International Convention and Exhibition Center project, the products have maintained stable performance after 8 years of exposure to a marine climate.

Environmental Performance Testing

Ask the manufacturer to provide environmental test reports. Qinglong products have passed green building material certification, with formaldehyde emission levels far below standard limits. This eco-friendly characteristic makes them suitable for a variety of indoor and outdoor applications.

It is recommended to entrust a third-party testing agency to conduct tests for objective data. Qinglong GRC products have passed multiple testing certifications and are of reliable, trustworthy quality.
