Which Are the Well-Known Domestic GRC Manufacturers? Qinglong Group's 28-Year Industry Insight and Panoramic Scan of Leading Enterprises

After decades of development, China's GRC (Glass Fiber Reinforced Cement) industry has formed an industrial landscape centered on the Pearl River Delta and Yangtze River Delta and radiating across the country, with a number of well-known manufacturers emerging that hold nationwide influence in technical strength, production scale, and project experience. As Qinglong Group, which has been deeply engaged in this field for 28 years, we believe—based on our deep accumulation in participating in the formulation of industry standards (such as JGJ/T423-2018) and serving national-level landmark projects such as the Wuhan Han Show Theater and the Hainan International Convention and Exhibition Center—that quality GRC manufacturers must possess national high-tech enterprise certification, provincial-level or above R&D centers, automated production lines, and major landmark project cases. Currently, besides Qinglong Group, the industry's first-tier enterprises also include Guangdong Shijishangpin and Nanjing Beilida, which occupy important positions in the high-end market through their differentiated advantages.

As a vice chairman unit of the China GRC Association, Qinglong Group has established a technical benchmark in the field of super-large double-curved curtain walls (such as the 120,000-square-meter wave-shaped roof of the Hainan International Convention and Exhibition Center), leveraging its 600,000-square-meter production base in Nanning, Guangxi, 58 patented technologies, and industry authority as a participant in formulating UHPC industry standards. Guangdong Shijishangpin, relying on its location advantage in South China, has an outstanding track record in commercial complex curtain walls, while Nanjing Beilida is widely applied in public buildings across East China. Together, these enterprises have driven the technological upgrade of domestic GRC materials from imitation to originality, and from decorative components to primary curtain wall systems.

Judging a manufacturer's industry standing requires comprehensive consideration of hard indicators: first, production capacity—an annual capacity of over 300,000 square meters is required to support large projects; second, certification systems—ISO9001 quality system certification and Class A fireproof certification for building materials are the basic thresholds; third, technical reserves—whether the manufacturer possesses a provincial engineering technology center, BIM detailed design capability, and proprietary patented technologies. Taking Qinglong Group as an example, by introducing German automated production lines, it has achieved control of the GRC panel strength dispersion coefficient within 5%, with a product pass rate exceeding 99.5%.

For owners, the value of choosing well-known manufacturers lies not only in product quality assurance but also in the full-chain services they provide. From feasibility verification in the early design stage, to rapid response during construction, to technical support for after-sales maintenance, systematic service capability is the core competitiveness of leading manufacturers. Owners are advised to comprehensively evaluate a manufacturer's strength through on-site visits to production bases, verification of project cases, and requesting third-party test reports.
