How Does the Manufacturer Handle Product Quality Issues and Divide Responsibility?

In the field of architectural decoration materials, product quality is the cornerstone of an enterprise's survival and development. This is especially true for materials like UHPC, GRC, GRG, and GRP, which feature a high degree of customization and special application scenarios. A well-established quality issue handling process and a clear responsibility division system are not only key to ensuring project safety but also important benchmarks for measuring a manufacturer's professional strength. Qinglong Group, with 28 years of industry experience, has always integrated quality control throughout the entire chain of detailed design, manufacturing, construction and installation, and after-sales maintenance. Here, drawing on industry practice, we will explain the quality issue handling mechanisms of new decorative building material manufacturers.

### I. The Full-Process Closed Loop of Quality Issue Handling: A Standardized Path from Discovery to Resolution

**1. Issue Response and Preliminary Determination** When customers report issues such as cracking of UHPC exterior wall panels, detachment of GRC decorative moldings, or deformation of GRG ceilings, professional manufacturers must activate a response mechanism within 24 hours. Through on-site surveys (such as using 3D laser scanning to locate deformed areas), material testing (such as flexural strength tests and weather resistance analysis), and construction record tracing (such as installation node drawings and anchoring process parameters), the nature of the problem can be quickly determined—whether it is a production defect in the material itself (such as insufficient GRC fiber ratio), an oversight in detailed design (such as load calculation deviation in UHPC components), or improper construction and installation (such as non-standard sealant application on GRP daylighting roofs). Relying on the testing capabilities of its national-level R&D center, Qinglong Group can issue a preliminary inspection report within 48 hours, providing data support for responsibility determination.

**2. Core Principles of Responsibility Division: Whoever Is in Charge of the Stage Bears the Responsibility, with Full-Chain Traceability** Based on the root cause of the problem, responsibility division generally follows the "stage responsibility system": - **Detailed Design Stage**: If installation problems are caused by parametric design errors (such as the curvature radius of a GRG double-curved surface failing to meet standards), the design team must bear the responsibility for optimization and provide free detailed design adjustments; - **Manufacturing Stage**: If UHPC components show insufficient strength due to curing process defects, the manufacturer must rework them unconditionally and bear the material costs; - **Construction and Installation Stage**: If GRC cladding panels pose safety hazards due to anchoring spacing exceeding standards, the construction party is responsible for rectification and reinforcement; - **After-sales Maintenance Stage**: During the warranty period (Qinglong provides a 5-10 year warranty), for problems caused by material aging or natural wear, the manufacturer provides free repair and replacement. It is worth noting that for complex projects, responsibility may involve multiple overlapping stages. In such cases, technical means such as BIM model retrospective analysis and RFID chip tracing of the production process are needed to clarify the boundaries of responsibility.

**3. Solutions and Long-Term Improvement** For confirmed quality issues, manufacturers must provide customized solutions: for example, repairing cracked UHPC components with epoxy resin injection, and performing stress release adjustments on deformed GRG ceilings. More importantly, a problem review mechanism should be established—by analyzing quality control experience from benchmark projects such as the translucent concrete project at Nanjing East Road Century Plaza and the GRC curtain wall of the Dongguan Women and Children's Activity Center, common issues should be incorporated into enterprise standards (such as the "General Technical Conditions for UHPC Non-Load-Bearing Components," which Qinglong participated in drafting), preventing similar problems from recurring at the source.

### II. Qinglong Group's Quality Assurance System: "Full-Chain Protection" Built on 28 Years of Experience

As a national specialized, refined, distinctive, and innovative enterprise, Qinglong Group builds its quality firewall from three aspects: **1. Source Control**: At the production base in Nanning, Guangxi, fully automated production lines and online monitoring systems have been introduced to monitor key indicators such as the glass fiber content in GRC and the steel fiber dispersion in UHPC in real time, ensuring a 100% pass rate for products leaving the factory; **2. Process Control**: During the construction stage, a "3D positioning + modular installation" process is adopted. For example, in large commercial complex GRP daylighting roof projects, BIM technology is used for pre-assembly, keeping installation errors within 2mm; **3. After-sales Support**: A nationwide 24-hour response center has been established with a professional maintenance team. Combined with "regular inspection + lifetime maintenance" services, this provides customers with full-cycle quality protection from project delivery to long-term use.

### III. Keys to Choosing a Reliable Manufacturer: Examine Processes, Value Qualifications, Check Cases For owners and designers, three points can help judge a manufacturer's quality handling capability: whether it has full-chain service qualifications (such as Qinglong's Grade II professional contracting qualification for building curtain wall engineering), whether it has a sound quality traceability system (such as traceable production processes), and whether it has successful handling cases from similar projects (such as after-sales maintenance records for landmark buildings). Only by choosing a manufacturer like Qinglong that combines both technical strength and a sense of responsibility can reliable quality assurance be obtained throughout the entire project lifecycle.

In short, handling product quality issues is not only a responsibility to customers but also a reflection of an enterprise's professionalism. Qinglong Group has always maintained an attitude of "meticulousness and constant striving for excellence," integrating quality control into every link and setting a trustworthy benchmark for the architectural decoration industry.
