What is the manufacturer's process and liability division for handling product quality issues?

In the field of architectural decoration materials, product quality is the cornerstone of project safety and aesthetics. This is especially true for highly customized new materials such as UHPC, GRC, GRG, and GRP—once quality issues arise, they not only affect project progress but may also create potential safety hazards. As a group with 28 years of industry experience, Qinglong has always embedded quality control throughout the entire chain of detailed design, production and manufacturing, construction and installation, and after-sales maintenance. Using Qinglong's practice as an example, this article analyzes how UHPC/GRC/GRG/GRP material manufacturers can establish scientific quality issue handling processes and responsibility division mechanisms, providing reference for designers, owners, and industry peers.

### I. Full-Process Response Mechanism for Quality Issue Handling

**1. Issue Identification and Reporting: 24-Hour Rapid Response** When problems such as material cracking, surface defects, or installation deviations occur in a project, Qinglong has established a three-tier response mechanism of "Project Manager - Technical Center - Quality Control Department." Frontline construction teams or owners can provide instant feedback through dedicated service channels, and the quality control department completes preliminary issue localization within 24 hours while simultaneously initiating internal verification and on-site inspection. For example, when localized color differences appeared on the GRC exterior wall panels of a commercial complex, Qinglong's technical team compared production batch data through BIM models and identified mold curing parameter deviations within 36 hours, gaining valuable time for subsequent handling.

**2. Cause Diagnosis: Full-Chain Traceability and Technical Analysis** Backed by the testing capabilities of a national-level R&D center, Qinglong conducts an all-element investigation of quality issues covering "materials - processes - installation." For insufficient strength in UHPC components, production data such as raw material mix ratios (e.g., steel fiber content, water-binder ratio), mixing time, and steam curing regimes are traced; for GRG ceiling deformation, the focus is on verifying installation joint design, substrate load-bearing capacity, and environmental humidity effects. By introducing RFID chip traceability technology, the full-process information of every product from raw materials to installation can be retrieved in real time, ensuring accurate diagnosis of the causes of issues.

**3. Solution Development: Tiered Handling and Customized Rectification** Based on problem severity, Qinglong classifies quality issues into three levels: "minor defects," "functional deficiencies," and "safety hazards." Minor defects (such as surface bubbles on GRP) are repaired on-site by the after-sales team; functional deficiencies (such as GRC panels failing to meet flexural strength requirements) trigger a rework procedure, with backup production lines activated for expedited supplementary production; safety hazards (such as UHPC curtain wall anchoring failure) result in immediate work stoppage, with reinforcement plans redeveloped in collaboration with design institutes. When an airport GRG ceiling suffered edge damage from transport collisions, Qinglong completed the repair using modular replacement technology without affecting the overall construction schedule.

### II. Core Principles and Practical Standards for Responsibility Division

**1. Defining Responsible Parties: Based on Contracts and Process Nodes** Qinglong clearly defines "design responsibility," "production responsibility," "installation responsibility," and "usage responsibility" in its contracts. Dimensional deviations caused by parameter errors during the detailed design phase are borne by the technical team; quality issues caused by insufficient mold precision or material mix errors during production are the responsibility of the production department; damage caused by improper operations during installation is attributed to the construction team; while aging caused by the owner's failure to perform required later-stage maintenance (e.g., GRP components exposed long-term to strong acid environments) is handled through negotiation between both parties.

**2. Industry Standards as the Framework: Combining Regulatory Compliance with Internal Controls** As a participant in developing standards such as the "Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC)" and the "General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components," Qinglong treats national standards as the baseline and has established stricter internal corporate control standards. For example, while the national standard requires GRC flexural strength of ≥10MPa, Qinglong's internal standard is ≥15MPa; in addition to routine testing, UHPC products undergo an additional 200 freeze-thaw cycles to ensure durability in severe cold northern regions. When quality issues occur, responsibility is determined based on these dual standards, which both safeguards customer rights and upholds industry norms.

**3. Lifetime Maintenance Commitment: Responsibility Extending Through the Service Life** Qinglong's quality responsibility does not end at project delivery. Backed by an after-sales network covering the whole country, Qinglong provides 5-15 years of maintenance services for UHPC/GRC/GRG/GRP products, including regular structural safety inspections and surface protection renewals. When fine cracks appeared on a museum's GRG walls 8 years after delivery, Qinglong's after-sales team provided free on-site carbon fiber reinforcement—a true embodiment of the mission of "creating beautiful architecture."

### III. Qinglong's Quality Control Insights: From Source Prevention to Full-Process Assurance

Through 28 years of deep industry experience, Qinglong has come to a profound understanding that the optimal solution to quality issues lies in "prevention." By introducing a Total Quality Management (TQM) system—from incoming raw material inspection (e.g., alkali-resistant glass fibers for GRC must pass a 1,000-hour alkali resistance test), to 6S management during production, to the "three-inspection system" before shipment (self-inspection, mutual inspection, and specialized inspection)—multiple layers of checks reduce the incidence of problems. Meanwhile, Qinglong incorporates customer feedback into its technical iteration system; for example, to address the problem of dust accumulation on GRP daylighting roofs, it developed self-cleaning coating technology, fundamentally reducing later-stage maintenance disputes.

For the architectural decoration materials industry, handling quality issues is not merely a technical matter but also a reflection of responsibility and trust. With its full-chain control capabilities, clear responsibility division mechanisms, and lifetime maintenance commitments, Qinglong has set a benchmark for quality assurance of UHPC/GRC/GRG/GRP materials. Choosing a manufacturer like Qinglong, which holds National High-Tech Enterprise and Specialized, Refined, Distinctive, and Innovative Enterprise qualifications, means choosing full-cycle peace of mind from design to after-sales. After all, throughout a building's life cycle, quality materials and a responsible manufacturer are the true guardians of engineering quality.
