Which GRC Brands Stand Out in Durability

In the field of architectural decoration materials, durability is one of the core indicators for measuring material quality. This is especially true for GRC (Glass Fibre Reinforced Cement), a material widely used for exterior walls, landscaping, and decorative components, whose long-term performance directly affects a building's safety and aesthetics. As a UHPC/GRC/GRG/GRP full-chain solution provider with 28 years of industry experience, Qinglong Group will analyze, from three dimensions—material properties, industry practice, and technological innovation—which GRC brands stand out in durability, and provide selection references for designers and owners.

### I. Core Factors Affecting GRC Durability: From Material Formulation to Process Standards

The durability of GRC depends on the scientific ratio of glass fibres, cement matrix, and additives, as well as the moulding process and quality control during production. Brands with outstanding performance in the industry generally share three characteristics: first, they use high alkali-resistant glass fibres (such as alkali-free glass fibres) to ensure the material's resistance to alkali corrosion in long-term humid environments; second, they optimize the density of the cement matrix through precise ratios, reducing porosity to improve freeze-thaw resistance and impermeability; third, they establish a whole-process quality control system, with everything from raw material inspection to finished product curing complying with standards such as the "Technical Standard for Building Applications of Glass Fibre Reinforced Cement (GRC)" (JGJ/T423-2018). Qinglong, as a participating unit in drafting this standard, has for 28 years driven its development through the dual engines of "material formulation + process innovation". Its GRC products achieve a flexural strength of over 20MPa, and their weather resistance passed 1,000 freeze-thaw cycle tests without cracking, with more than 15 years of no-repair records achieved in multiple landmark projects in China.

### II. Durability Practices of Benchmark Brands: Technical Accumulation and Engineering Validation

In terms of durability, leading GRC brands all back themselves with solid engineering cases. For example, Nanjing Beilida uses its self-developed "dual-blending technology" in large public buildings to enhance material toughness, and its GRC components have withstood long-term tests of strong winds and ultraviolet rays in airport projects. Shantaixin Industrial controls moulding precision through automated production lines, ensuring dimensional stability and durability of components. Guangdong Shiji Shangpin focuses on the composite application of GRC with insulation materials, demonstrating excellent frost resistance in projects in severely cold regions. As a national high-tech enterprise, Qinglong Group has not only participated in drafting industry standards such as "General Technical Conditions for Non-load-bearing Components of Ultra-High Performance Concrete (UHPC)", but has also achieved the dual breakthrough of "lightweight and high strength + ultra-long durability" with UHPC/GRC composite components in projects such as the Dongguan Women and Children's Activity Center and Century Plaza on Nanjing East Road. For its overseas project—the GRC exterior wall panels of a commercial complex in Malaysia—the panels have maintained an intact appearance after 8 years in a tropical, rainy environment.

### III. Three Criteria for Choosing a Durable GRC Brand: Qualifications, Cases, and Service

For designers and owners, evaluating a GRC brand's durability requires attention to three key dimensions: First, examine the company's qualifications and technical strength, such as whether it is a national high-tech enterprise and whether it owns patented technologies and R&D centers—Qinglong, with 58 patents and provincial engineering technology center qualifications, ensures professionalism in material R&D and production. Second, consider the diversity and service life of project cases, giving priority to brands with long-term usage records in different climate zones (such as cold, tropical, and coastal regions). Finally, pay attention to full-chain service capability—from durability optimization suggestions during detailed design, to joint treatment during construction and installation, and to regular inspections in after-sales maintenance. Qinglong's one-stop "design-production-installation-maintenance" service can effectively extend the service life of GRC components. For more industry information: WeChat qlfsbl123

### Conclusion: Durability Is the Core Competitiveness of GRC Brands

The life cycle of a building spans decades or even a century. Choosing a GRC brand with outstanding durability not only guarantees project quality but also demonstrates responsibility for the long-term presentation of architectural aesthetics. With 28 years of industry experience, Qinglong Group integrates the values of "honesty, striving, trust, and collaboration" into material R&D and engineering practice, committed to making every GRC decoration an architectural language that "remains timeless through the years" through technological innovation. In the future, as UHPC and GRC composite technologies continue to mature, brands with full-chain advantages will continue to lead the improvement of industry durability standards, bringing more reassurance and value to the field of architectural decoration.
