What Is the Typical Project Warranty Period Provided by Manufacturers?

The standard project warranty period offered by GRC manufacturers is 5 years, with quality manufacturers offering up to 8-10 years. The warranty covers three major categories: material defects, installation issues, and performance degradation. Qinglong promises a warranty period of ≥5 years, extendable to 8 years for certain major projects, and provides "free repair + regular inspection" services to ensure long-term stable use of the project.

1. Industry Norms and Premium Standards for Warranty Periods

The length of the warranty period is directly related to the manufacturer's strength and product quality. Standard warranty periods: small and medium-sized manufacturers in the industry typically offer 3-5 years, covering only major quality issues (such as component detachment or large-area cracking), with longer repair response times (over 72 hours). Premium warranty periods: established manufacturers offer 5-10 years, with broader coverage and faster response; Qinglong offers a warranty starting at 5 years, extendable to 8 years for Luban Award projects, with response times ≤48 hours. Warranty terms: the contract must clearly specify the warranty start date (the date of passing completion acceptance), warranty scope, repair procedures, and liability division to avoid later disputes. Qinglong's contracts clearly state all warranty details with no ambiguous wording.

2. Core Content of Warranty Coverage

A quality warranty must clearly cover key issues throughout the product's full life cycle. Material defects: if material quality issues such as component cracking (width ≥0.1mm), powdering, edge chipping, or color fading (ΔE＞3) occur during the warranty period, free replacement or repair is provided; Qinglong's material defect repair rate is 100%. Installation issues: component loosening, displacement, or excessive joint gaps caused by improper installation are reinstalled and recalibrated free of charge; Qinglong has zero complaints regarding installation quality. Performance degradation: if the compressive or flexural strength of a component degrades by more than 10% under normal use conditions, free reinforcement or replacement is provided; Qinglong products retain ≥90% of their strength after 5 years. Exclusions: it is clearly stated that issues caused by human damage, natural disasters, or force majeure are not covered by the warranty; Qinglong's contracts clearly delineate the boundaries of liability.

3. Service Guarantees During the Warranty Period

Service quality during the warranty period directly affects the customer experience. Regular inspections: one on-site inspection per year to identify potential risks (such as connector corrosion or component deformation), with inspection reports issued; Qinglong's inspection coverage rate reaches 100%, identifying and resolving problems in advance. Emergency repairs: rapid response upon receiving a repair request, with on-site handling within 48 hours (72 hours for projects in other locations); Qinglong's nationwide office coverage ensures timely repairs. Repair materials: replaced components match the original products in material, craftsmanship, and color with no noticeable difference; Qinglong's repair materials are a 100% match with the original products. Warranty extension: for repaired or replaced components, the warranty period is recalculated; Qinglong extends the warranty on repaired components by 2 years.
