How to Judge GRC Product Quality? Qinglong's Professional Guide to GRC Quality Assessment

Assessing GRC product quality requires establishing a scientific evaluation system. High-quality GRC products should feature stable mechanical performance, excellent durability, and refined appearance. Based on 28 years of quality control experience, Qinglong GRC has developed a systematic quality evaluation methodology.

During the specific evaluation process, first review the test reports, focusing on mechanical performance indicators such as flexural strength and impact strength. Second, examine the appearance quality, including dimensional accuracy, surface flatness, and color uniformity. Third, understand the durability performance, such as frost resistance, weather resistance, and other long-term performance indicators. During the acceptance inspection of the Wuhan Hanxiu Theater project, the owner commissioned a third-party testing agency to conduct sampling tests, and all indicators of Qinglong GRC products exceeded the standard requirements.

Mechanical Performance Evaluation

A flexural strength ≥18MPa is the basic requirement. An impact strength ≥15kJ/㎡ reflects toughness. The strength variation coefficient should be controlled within 8%. These indicators ensure safe use.

Appearance Quality Inspection

Dimensional deviations should be kept within the allowable range. Surface flatness must meet requirements. Colors should be uniform without variation. These inspections ensure the aesthetic effect.

Durability Testing

The number of freeze-thaw cycles reflects frost resistance. Weather resistance testing evaluates long-term performance. These tests predict the service life.

Installation Quality Evaluation

The uniformity of panel joints affects the overall effect. The quality of joint treatment is related to waterproofing performance. These evaluations ensure project quality.

Quality evaluation requires professional knowledge and experience. It is recommended to commission a professional institution for testing. Qinglong GRC products have stable quality and are open to testing and verification.
