How to Judge GRC Product Quality? A Detailed Explanation of Qinglong GRC Manufacturer's Quality Evaluation Standards

Evaluating GRC product quality requires professional knowledge. This article introduces how to scientifically assess GRC product quality from multiple dimensions, helping you make accurate judgments.

First, observe the product's appearance quality. High-quality GRC products have a flat surface, uniform color, and neat edges and corners. A crisp sound when tapped indicates good density. Measure dimensional deviations; qualified products should have length deviations controlled within ±2mm. Qinglong products adopt advanced production processes, achieving dimensional precision of ±1mm, far exceeding industry standards.

Strength Performance Testing

Flexural strength is a key indicator; high-quality products should be ≥18MPa. Qinglong products measure 20-25MPa, exceeding standard requirements.

Durability Assessment

Observe the water absorption rate through water immersion tests; high-quality products should have an absorption rate below 10%. Qinglong products are controlled within 6%, offering better durability.

Environmental Performance Testing

Ask the manufacturer for environmental testing reports. Qinglong products have passed green building material certification, with formaldehyde emissions far below standard limits.

It is recommended to commission a third-party testing agency to conduct tests and obtain objective data.
