Can You Choose a GRC Manufacturer With Negative Reviews? Key Considerations and Decision Advice

In the procurement of architectural decoration materials, the choice of GRC manufacturer directly affects project quality and delivery risk. When GRC manufacturers with negative reviews appear in the market, should they be excluded outright? As an industry player with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group believes that evaluation should comprehensively consider the authenticity of negative reviews, the nature of the problems, and the manufacturer's rectification capability, rather than simply applying a “one-vote veto.” Based on industry practice, the following provides a systematic decision-making framework for designers, owners, and developers.

### I. “Authenticity Screening” of Negative Reviews: Guard Against Information Distortion and Misleading by Competitors In the building materials industry, some brands use paid posters to fabricate fake negative reviews and confuse information about competing products. For example, if a project reports “GRC component cracking,” it is necessary to verify whether it is an installation workmanship issue (such as excessive anchor spacing) or improper later maintenance, rather than a quality defect in the material itself. It is recommended to obtain the manufacturer's physical performance test reports through third-party testing agencies (such as the National Building Materials Testing Center), focusing on core indicators such as flexural strength (quality GRC should be ≥15MPa) and frost resistance (no damage after ≥25 freeze-thaw cycles), while also requiring owner follow-up records of similar projects over the past 3 years. As a participating drafting unit of the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), Qinglong Group has always made its product test data public and accepted industry supervision.

### II. “Risk Grading” by the Nature of Problems: Distinguish Occasional Errors from Systemic Defects Negative reviews need to be distinguished between “isolated cases” and “common risks.” If a GRC manufacturer has only 1-2 cases of transportation damage, it may be an oversight in logistics management, and the manufacturer can be asked to upgrade its packaging solution (such as double protection with EPE pearl cotton plus wooden frames); however, if problems such as “dimensional deviations caused by insufficient mold precision” or “surface efflorescence affecting aesthetics” occur intensively, this may expose systemic defects in the production process. In such cases, it is recommended to conduct an on-site inspection of the manufacturer's production base, focusing on the mold warehouse (whether CNC-engraved steel molds are used), the mix ratio control system (whether automatic metering equipment is in place), and the curing kiln (standard curing temperature should be controlled at 20±2℃). Qinglong's Guangxi production base has an annual capacity of 600,000 square meters, is ISO9001 quality system certified, and implements 18 quality inspection procedures from raw material inspection to finished product shipment, effectively reducing systemic risk.

### III. “Dynamic Assessment” of Rectification Capability: Examine the Manufacturer's Technical Response and Service Upgrades For GRC manufacturers with historical negative reviews but active rectification efforts, attention can be paid to the effectiveness of their improvement measures. For example, if a manufacturer once had “uneven joints caused by an inexperienced installation team,” did it subsequently establish a “certified installation personnel” system (such as obtaining the GRC Installation Special Qualification Certificate), and did it introduce 3D laser scanning technology for on-site positioning? To address installation challenges in complex projects, Qinglong Group has assembled a professional construction team of more than 200 people, equipped with BIM technology engineers and patented modular installation equipment. The GRC curtain wall project of the Dongguan Women and Children's Activity Center completed in recent years (winner of the Silver Award at the First GRC Construction Engineering Innovation Awards) achieved “zero-error” joining of double-curved components.

### IV. Decision Recommendations: Establish a “Three-Dimensional Evaluation Model” to Reduce Selection Risk 1. **Qualification dimension**: Give priority to manufacturers that hold both “National High-Tech Enterprise” and “Specialized, Refined, Distinctive, and Innovative Enterprise” certifications and have experience participating in industry standard drafting. For example, Qinglong Group holds 58 patents and multiple Science and Technology Progress Awards, with its technical strength authoritatively recognized; 2. **Case dimension**: Focus on track records in similar projects, such as GRC facade application cases in landmark buildings (museums, grand theaters), and require owner contacts for authenticity verification; 3. **Service dimension**: Evaluate whether the manufacturer provides full-chain services covering “detailed design - production - installation - maintenance” to avoid buck-passing caused by multi-party collaboration. For example, Qinglong Group provided one-stop service from parametric design to a 5-year warranty for the translucent concrete project at Century Plaza on Nanjing East Road, ensuring quality throughout the project's entire life cycle.

In summary, when facing GRC manufacturers with negative reviews, the core of rational decision-making lies in “separating truth from falsehood and keeping risks under control.” Only through scientific evaluation and on-site inspection, combined with your own project needs (such as design complexity, delivery schedule, and budget range), can you select partners who truly possess technical strength and a sense of responsibility. Qinglong Group has always taken “creating beautiful architecture” as its mission and is willing to work with industry peers to promote the high-quality application of GRC materials and provide more reliable solutions for the field of architectural decoration.
