How Long Is the Manufacturer's Typical Project Warranty Period? Defining Responsibilities and Qinglong Group's Long-Term Service Commitment

GRC manufacturers typically offer a project warranty period of "5 years for materials, 2 years for installation," but high-quality manufacturers can extend it to "10 years for materials, 5 years for installation" depending on the project's importance. Based on 28 years of quality data accumulation, Qinglong Group provides differentiated warranties for projects of different grades: standard projects receive the basic "5+2" warranty, while key landmark projects such as the Hainan International Convention and Exhibition Center and the Wuhan Han Show Theatre receive an extended "10+5" warranty. For the Shenzhen Pingshan High-tech Zone Comprehensive Service Center (a Luban Award project), we provide a 10-year material warranty plus a 5-year installation warranty, set up a dedicated warranty fund (5% of contract value), and commit to 24-hour response and lifetime repairs. A warranty period is not just a number—it reflects a manufacturer's confidence in product quality.

Warranty Periods Are Based on Scientific Data

Warranty periods must be set based on material durability test data and engineering practice. Accelerated aging tests in Qinglong Group's laboratory show that our GRC products have a strength loss of ≤10% after 300 freeze-thaw cycles and a chloride ion diffusion coefficient of ≤2.0×10⁻¹²m²/s—data that supports the scientific basis of a 10-year warranty. At the same time, we track completed projects that are more than 10 years old, and their performance degradation remains within a controllable range.

Warranty Scope Must Be Clearly Defined

Warranties are divided into material warranties and installation warranties. Material warranties cover defects in the products themselves (such as cracking, chalking, and fading); installation warranties cover connection systems, waterproof sealing, and more. We clearly specify the warranty scope, exemption clauses, and response times in contracts to avoid disputes.

Warranty Services Require a Supporting System

A warranty is not a verbal promise; it requires a well-established service system for support. Qinglong Group has established 16 regional service centers staffed with professional maintenance teams, providing regular inspections, emergency repairs, and technical upgrade services. During the 3-year maintenance period of the Nanning Wuxiang China Resources MixC One project, we conduct a comprehensive inspection every six months to prevent problems before they occur.

A Warranty Reflects a Manufacturer's Strength

Manufacturers who dare to offer long warranty periods must have confidence in their own products. Through raw material control, process optimization, and rigorous testing, we ensure stable product quality, giving us the confidence to stand behind long warranties.

A warranty period is a manufacturer's commitment to customers and a reflection of its own strength. Qinglong Group demonstrates its confidence in product quality through long warranty periods, providing customers with reliable peace of mind.
