When Assessing GRC Manufacturers, What Are the Core Criteria for Evaluating Technical Strength? The Five-Dimensional Evaluation System Built by Qinglong Group

To assess the technical strength of a GRC manufacturer, a systematic evaluation of five core dimensions is required: "R&D innovation capability, process equipment level, quality control system, project experience reserve, and depth of technical service." As an industry technology leader, Qinglong Group believes that a quality manufacturer should simultaneously possess: provincial-level or higher R&D center qualifications, fully automated production lines, ISO9001-certified quality control, complex project cases at the 10,000-square-meter scale, and full-cycle technical service capability from design to operation and maintenance. We recommend that customers adopt a four-step method—on-site factory audits, technical defenses, case tracing, and data verification—to see through the promotional facade and gain insight into true strength.

R&D innovation is the source of sustained leadership. Qinglong Group holds 58 authorized patents, with annual R&D investment exceeding 5% of revenue, and has led or participated in the formulation of 7 national and industry standards, including the "Technical Standard for Building Application of Glass Fibre Reinforced Cement (GRC)" (JGJ/T423-2018). We have a materials laboratory and a structural laboratory equipped with advanced instruments such as scanning electron microscopes and fatigue testing machines, enabling full-chain research from microscopic mechanisms to macroscopic performance. Customers should focus on examining the manufacturer's patent quality, standards participation, and laboratory testing capabilities.

Process equipment is the guarantee for translating technology into practice. We have introduced German fully automatic spraying production lines, five-axis CNC mold machining centers, and intelligent curing systems, achieving directional fiber spraying, vacuum dewatering, and precise temperature and humidity control. During evaluation, attention should be paid to equipment brands, automation rates, and the control precision of key process parameters (such as fiber dispersion uniformity). The data-driven management of Qinglong Group's production lines ensures a product strength variation coefficient of ≤5%.

Project experience is the ultimate test of strength. Customers should require manufacturers to provide at least 3 similar project cases completed more than 5 years ago and conduct on-site background checks to understand long-term performance. The technical challenges Qinglong Group overcame in national-level landmark projects such as the Wuhan Han Show Theatre and the Hainan International Convention and Exhibition Center are direct proof of our ability to solve complex problems.
