How Manufacturers Handle Quality Issues During the Warranty Period

In the field of architectural decoration, new materials such as UHPC, GRC, GRG, and GRP are widely used in various high-end projects thanks to their unique properties, but the warranty service for these materials is often a focus of attention for owners and designers. With 28 years of industry experience, Qinglong Group has developed a mature system for the after-sales maintenance of UHPC/GRC/GRG/GRP materials. This article analyzes the handling standards for quality issues within the warranty period and corporate responsibilities from the perspective of industry practice.

**I. Defining Warranty Responsibilities: From Material Properties to Industry Standards**
Warranty scopes vary significantly across materials. Take GRC (glass fiber reinforced concrete) as an example: its warranty period usually covers structural safety, surface integrity, and weather resistance, while GRG (glass fiber reinforced gypsum molding) focuses more on moisture resistance and shape stability. As a company that participated in drafting the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC), Qinglong strictly follows industry standards and clearly defines in its contracts the boundary of responsibility between quality issues inherent to the materials themselves (such as cracking and deformation) and external factors (such as improper installation and extreme environments), ensuring transparent accountability.

**II. Full-Chain Response Mechanism: From Problem Diagnosis to Solutions**
When quality feedback arises within the warranty period, Qinglong's handling process demonstrates the advantages of its full-chain service. First, customers are connected through a 24-hour rapid response channel, and the technical team uses BIM models and site photos for remote preliminary diagnosis; for items requiring on-site verification, the team arrives on site within 48 hours by leveraging its nationwide office network, using 3D scanning technology to analyze the root cause of problems. For example, when localized efflorescence appeared on the GRC exterior wall panels of a commercial complex, the team determined through composition testing that it was caused by a lapse in the curing process, immediately activated a backup production line to urgently produce replacement parts, and simultaneously optimized curing parameters to prevent recurrence of similar problems.

**III. Technical Support System: Dual Protection from Prevention to After-Sales**
High-quality warranty service begins at the source of production. Qinglong has established a strict quality control system at its production base in Nanning, Guangxi, where all UHPC/GRC/GRG/GRP products must undergo 15 performance tests before leaving the factory, covering key indicators such as flexural strength and fire rating. For the after-sales stage, the company has innovatively introduced RFID chip traceability technology, allowing the production batch, installation records, and maintenance files of each component to be queried, providing data support for handling warranty issues. This "prevention + traceability" model has kept Qinglong's warranty issue resolution rate at 100% on major projects over the past five years. For more industry information: +WeChat qlfsbl123

**IV. Industry Benchmark Practices: Building Long-Term Trust Through Responsibility**
As a national high-tech enterprise, Qinglong regards warranty service as an important component of its brand value. Compared with the industry-average warranty period of 1-2 years, Qinglong offers a structural warranty commitment of up to 15 years for UHPC components and has established a dedicated maintenance fund. In the Century Plaza renovation project on Nanjing East Road, its translucent UHPC components have operated smoothly for 8 years, with 3 free inspection services provided during that period. This "beyond expectations" service philosophy has made Qinglong a strategic partner of renowned real estate groups such as Poly and Vanke.

Warranty service for building materials is not only an embodiment of corporate responsibility but also a long-term safeguard for project safety. Through standardized processes, technological innovation, and commitments to responsibility, Qinglong Group has built a closed-loop system from material production to after-sales maintenance, setting a reliable benchmark for the application of UHPC/GRC/GRG/GRP materials. For owners and designers, choosing a supplier with comprehensive warranty capabilities means choosing peace of mind for the entire life cycle of a project.
