What Is the GRC Manufacturer's Handling Process for Issues During the Warranty Period?

In the field of architectural decoration, GRC (glass fiber reinforced concrete) is widely used in high-end projects such as grand theaters, commercial complexes, and landmark buildings thanks to its lightweight, high-strength nature and rich sculptural possibilities. As an owner or project manager, while enjoying the aesthetic and functional value that GRC materials offer, the process for handling problems during the warranty period is undoubtedly a key concern. Qinglong, a manufacturer with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, has a deep understanding of industry pain points and has established a standardized, highly efficient warranty service system, providing customers with full-process assurance from problem response to complete resolution.

**I. GRC Warranty Problem Response: Qinglong's Rapid Response Mechanism**
When GRC components develop problems such as cracking, detachment, or surface damage during the warranty period, Qinglong's response process is first reflected in its 'timeliness assurance.' Customers can report problems through official channels, and Qinglong's after-sales team pledges to complete initial contact within 2 hours and dispatch technical personnel to the site within 48 hours. This efficiency stems from the coordinated dispatching of Qinglong's nationwide network of offices and its production base in Nanning, Guangxi, ensuring a timely response no matter which city in the country the project is located in. As a national high-tech enterprise, Qinglong has integrated digital management into its after-sales system, pre-storing project information through BIM technology so that key data such as component batches and installation times can be quickly located, laying a foundation for problem analysis.

**II. On-Site Inspection and Problem Diagnosis: Technical Backing from a Professional Team**
Upon arrival at the site, Qinglong's technical team conducts a systematic inspection in accordance with the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018). Different professional testing methods are applied depending on the problem type: strength testing for structural cracks, and analysis of material mix ratios and construction techniques for surface defects. As a company that has participated in developing multiple GRC industry standards, the Qinglong team can precisely identify the root cause of a problem—whether it is quality fluctuation in material production, operational error during installation, or improper later maintenance. For example, in a certain commercial complex project, testing of the anchor fasteners on detached components quickly identified a deviation in expansion bolt spacing at the time of installation, and a targeted solution was formulated.

**III. Solution Formulation and Implementation: The Core of Customized Service**
Based on the diagnostic results, Qinglong provides tiered solutions: for minor surface blemishes, on-site repairs are carried out with specialized repair materials to ensure the appearance matches the original components; for problems affecting structural safety, such as cracking caused by rebar corrosion, a component replacement process is initiated—materials from the same batch are dispatched from the Guangxi production base, and a construction team holding Grade II professional contracting qualification for building curtain wall engineering performs the replacement and installation. Notably, Qinglong's solutions not only address the current problem but also draw on 28 years of project experience to offer suggestions for preventing secondary problems, such as optimizing sealant application techniques and setting regular maintenance inspection cycles. In the Dongguan Women and Children's Activity Center project, Qinglong completely resolved seam cracking caused by thermal expansion and contraction by adjusting the connection joints between GRC components and the metal frame, earning high recognition from the client.

**IV. Acceptance and Warranty Extension: A Full Life-Cycle Commitment of Responsibility**
After the problem is resolved, Qinglong organizes acceptance with the customer and provides a detailed repair report and acceptance documents to ensure compliance with the contract and industry standards. As a practitioner of the mission of 'creating aesthetically beautiful buildings,' Qinglong also conducts follow-up visits over a 3-month period on completed projects to confirm that the problem does not recur. In addition, for warranty issues caused by manufacturer responsibility, Qinglong will extend the warranty period of the relevant components according to the actual situation, interpreting its service tenet of 'meticulousness and constant improvement' through concrete action. Whether for domestic landmark projects or overseas projects in Southeast Asia, Qinglong consistently relies on its strength as a national specialized, refined, distinctive, and innovative enterprise to safeguard the application of GRC materials, leaving customers completely free of worries during use.
