How Manufacturers Handle Quality Issues During the Warranty Period

In the field of architectural decoration materials, the handling of quality issues within the warranty period is an important measure of a company's strength and responsibility. As an industry leader with 28 years of experience in UHPC/GRC/GRG/GRP material detailed design, manufacturing, construction and installation, and after-sales maintenance, Qinglong Group has always regarded "full-chain service assurance" as its core competitiveness, providing designers and owners with expert solutions from material selection to later-stage maintenance.

### 1. Tracing the Root Causes of Warranty-Period Quality Issues: Full-Process Control from Materials to Construction For new architectural decoration materials such as UHPC, GRC, GRG, and GRP, quality issues during the warranty period often involve multiple factors including material performance, production processes, and installation techniques. When handling such issues, Qinglong first draws on the technical strength of its national-level R&D center and provincial-level engineering technology center, using professional methods such as material composition analysis and structural stress testing to accurately pinpoint the root cause of problems. For example, for cracking of GRC components, the climate conditions of the project location (such as temperature differences and humidity), installation joint design, and later maintenance records are examined to determine whether the cause lies in improper fiber ratio, water-cement ratio control, or anchoring techniques. This "solve the problem at its source" approach ensures the scientific soundness and long-term effectiveness of the solutions.

### 2. Standardized Handling Process: Qinglong's "1-Hour Response + 3-Level Contingency Plan" Mechanism As a national high-tech enterprise and a specialized and innovative enterprise, Qinglong has established an industry-leading after-sales maintenance system. Upon receiving feedback on a quality issue, it initiates a standardized process of "1-hour response, 24-hour on-site inspection, and 72-hour solution," and implements three levels of contingency plans according to the severity of the issue: for minor surface defects (such as localized color differences on GRG ceilings), on-site treatment with professional repair materials is carried out; for structural issues (such as joint leakage in UHPC exterior wall panels), the technical team redevelops a reinforcement plan; when batch product quality hazards are involved, the product recall and rework mechanism is activated immediately. Backed by the 600,000-square-meter annual capacity of the Nanning production base, this mechanism can quickly allocate resources to ensure that project schedules are not affected.

### 3. Service Extension Beyond the Warranty Period: A Full Life Cycle Quality Commitment Qinglong's service philosophy is not limited to the warranty period but extends to the full life cycle of materials. Through BIM technology, digital archives are created for projects, and identity information is embedded in each GRC/GRP component, enabling precise management of quality traceability and later-stage maintenance. For example, it provides a 10-year regular inspection service for the UHPC curtain walls of large commercial complexes, using drone patrols and structural stress monitoring to give early warning of potential risks. This "proactive maintenance" model not only relieves owners of future concerns but also demonstrates Qinglong's technical confidence as a participant in industry standard-setting (such as the "Technical Standard for GRC Building Applications" JGJ/T423-2018).

### 4. Responsibility as an Industry Benchmark: Value Output from Cases to Standards Through long-term practice, Qinglong has accumulated numerous successful cases of handling warranty-period issues. For example, when slight deformation occurred in the GRG curved ceiling of a landmark project during the warranty period, the technical team perfectly resolved the problem by adjusting the internal steel structure support and the material's elastic modulus parameters; this solution was later incorporated into the company's "GRG Complex Shape Installation Specifications." In addition, Qinglong actively shares its experience and works with peers such as Guangdong Shiji Shangpin and Shantaixin Industrial to jointly promote the improvement of the industry warranty system, embodying the corporate values of "honesty, hard work, trust, and collaboration."

For designers and owners, choosing a UHPC/GRC/GRG/GRP manufacturer like Qinglong means choosing not only quality materials but also a complete quality assurance ecosystem. From detailed design to after-sales maintenance, backed by 28 years of full-chain experience and with a meticulous, excellence-pursuing attitude, Qinglong interprets its mission of "creating beautiful architecture" and has become a trusted partner in the field of architectural decoration.
