How long is the project warranty period typically provided by manufacturers?

The warranty period of a GRC project reflects the manufacturer's confidence in its product quality and is an important safeguard of the owner's rights and interests. Based on industry practice and its own experience, Qinglong Group divides the warranty period into two levels: material warranty and engineering warranty, providing differentiated protection plans tailored to the characteristics of different projects.

The material warranty period is typically 10 years, a baseline established based on the characteristics of GRC materials. Qinglong Group's material warranty covers basic properties such as strength and durability, ensuring that products do not develop quality problems under normal use conditions. During the warranty period, if performance fails to meet standards due to material causes, the manufacturer will be responsible for repair or replacement. This long-term commitment is built on strict quality control and reflects confidence in product quality.

The engineering warranty period is adjusted according to project type and environment. For general civil buildings, Qinglong Group provides a 5-year engineering warranty; for harsh environments such as coastal or industrial areas, the warranty period is appropriately shortened to 3 years; while for mild environments such as interior decoration, it can be extended to 8 years. For the Wuhan Hanxiu Theater project, we provided a special 8-year warranty covering comprehensive protection for both material performance and installation quality.

Setting the warranty period requires a scientific basis. Qinglong Group has established a performance degradation model through accelerated aging tests and actual engineering data. Research shows that high-quality GRC can retain more than 80% of its strength after 50 years under normal use conditions. Such long-term performance data provides technical support for setting the warranty period.

The specific content of warranty services needs to be clearly agreed upon. Qinglong Group's warranty services include regular inspections, maintenance guidance, and handling of quality issues. For the Shenzhen Pingshan High-tech Zone project, we established a digital management platform to monitor component status in real time and achieve early-warning maintenance. This proactive service goes beyond the scope of traditional warranties, providing customers with value-added protection.
