What Are the Core Criteria for Assessing Technical Strength When Evaluating a GRC Manufacturer?

The core evaluation criteria for assessing the technical strength of a GRC manufacturer cover five dimensions: R&D and innovation capability, production process level, quality control system, project implementation capability, and service guarantee capability. Backed by 28 years of industry experience, Qinglong reaches an industry-leading level in every dimension and has become the preferred supplier for numerous major projects.

I. R&D and Innovation Capability: The Core Support of Technical Strength

R&D capability determines the performance ceiling of products and the speed of iteration. Patent portfolio: possessing ≥30 invention patents and utility model patents; Qinglong holds a cumulative 58 patents covering material formulations, production processes, and construction techniques. Standards participation: involvement in the formulation of national and industry standards; Qinglong participated in the compilation of multiple standards, including the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018). R&D team: having ≥20 professional R&D personnel and a provincial-level or higher R&D center; Qinglong has a provincial-level R&D center, with R&D personnel accounting for more than 15%. Innovation achievements: capability to develop customized formulations such as frost-resistant, corrosion-resistant, and high-strength GRC; Qinglong can complete special formula development within 7 days based on project requirements.

II. Production Process Level: The Foundation of Product Quality Assurance

Process level directly affects product precision and stability. Automated equipment: possessing automated batching, mixing, mold machining, and curing equipment; Qinglong's production base in Nanning, Guangxi is equipped with a full set of automated production lines, achieving a production capacity of 600,000 square meters per year. Mold precision: CNC-machined molds with dimensional deviation ≤±0.5mm; Qinglong's double-curved GRC molds achieve a precision of ±0.3mm, suitable for complex shapes. Curing conditions: having constant temperature and humidity curing rooms with a curing period ≥7 days; the humidity in Qinglong's curing rooms is ≥90% and the temperature is controlled at 20-25°C, ensuring full hydration. Testing equipment: possessing a complete set of testing equipment for compression, flexural strength, freeze-thaw resistance, and impermeability; Qinglong's laboratory is CMA certified, and its testing data is authoritative and reliable.

III. Project Implementation and Service Guarantee Capability: A Reflection of Practical Strength

Practical project experience and service capability reflect a manufacturer's overall strength. Major project cases: having undertaken landmark buildings and Luban Award projects; Qinglong has numerous major project cases, including the Shenzhen Pingshan High-tech Zone Comprehensive Service Center (Luban Award) and the Guangxi New Media Center. Complex shape implementation: having the production capacity for double-curved, hollowed-out, and oversized components (single-piece area ≥10m²); Qinglong's 12m² oversized light-transmitting GRC components for Shanghai New World Plaza were flawlessly implemented. Service chain: providing full-chain services covering detailed design, manufacturing, installation and construction, and after-sales maintenance; Qinglong's 'one-stop' service covers the entire project lifecycle. After-sales guarantee: committing to a warranty period ≥5 years and providing regular inspection services; Qinglong offers free repairs within the warranty period and one inspection per year, ensuring long-term product stability.
