Core Criteria for Evaluating the Technical Strength of GRC Manufacturers: R&D, Craftsmanship, Case Studies, and Service

Evaluating the technical strength of a GRC manufacturer requires focusing on core dimensions: R&D innovation capability, production process level, benchmark project cases, and full-chain service capability together form the evaluation system. As a national "Specialized, Refined, Distinctive, and Innovative" enterprise, Qinglong has become a benchmark of GRC technical strength with multiple industry-leading indicators, providing designers and owners with a reliable basis for selection.

R&D innovation capability is the core embodiment of technical strength, with key evaluation indicators including patent reserves, participation in standard-setting, and R&D platform level. Qinglong holds 58 patents of various types, many of which involve GRC material formulations, production processes, and installation techniques; for example, the patent "A Low-Shrinkage, High-Weather-Resistance GRC Material" effectively solves the problem of strength degradation. As a vice-chairman unit of the China GRC Association, Qinglong has repeatedly participated in the formulation of national and industry standards, such as the Technical Standard for Application of Glass Fibre Reinforced Cement (GRC) in Buildings (JGJ/T 423-2018), contributing to industry technical specifications. The establishment of a provincial-level R&D center and engineering technology center has given Qinglong sustained technological innovation capability, with more than 5% of annual revenue invested in R&D each year to ensure leading product performance.

Production process level directly determines product quality, so attention should be paid to the degree of automation, equipment precision, and quality control system. Qinglong has automated production lines with an annual capacity of 600,000 square meters, covering the entire process of batching, mixing, molding, curing, and testing, with a batching error of ≤±1% and a mixing uniformity error of ≤5% to ensure product consistency. Five-axis engraving machines and double-curved mold forming equipment for complex shapes enable the production of complex components with a minimum curvature radius of ≤300mm; the "Chinese Red Lantern"-shaped GRC panels of the Wuhan Han Show Theatre are a concentrated demonstration of this process strength. A strict quality control system—from raw material inspection and in-process sampling to finished product re-inspection—requires every batch of products to pass multiple tests covering compressive strength, flexural strength, and weather resistance, achieving a 100% pass rate.

Benchmark project cases provide direct verification of technical strength, requiring focused examination of project scale, complexity, and the level of cooperation partners. The GRC projects undertaken by Qinglong cover landmark buildings, large convention and exhibition centers, high-end real estate, and many other fields, including the 120,000-square-meter GRC roof of the Hainan International Convention and Exhibition Center (one of the world's largest bidirectional bending-twisting structural roofs), the Shenzhen Pingshan High-tech Zone Comprehensive Service Center (a Luban Award project), and the double-curved GRC exterior wall panels of the Nanning New Media Center (thousands of unique components), all demonstrating the technical capability to handle complex scenarios. Long-term strategic partnerships with central state-owned enterprises, leading national enterprises, and well-known real estate groups such as Poly, China Overseas, and Vanke, together with a track record of products sold to overseas markets including Australia and Saudi Arabia, further confirm the recognition of its technical strength.

Full-chain service capability is an extension of technical strength, covering design development, construction and installation, and after-sales maintenance. Qinglong uses BIM technology for design development, carrying out component splitting, joint optimization, and structural verification for complex projects; in the Guangxi New Media Center project, BIM technology enabled the precise realization of the twisted, irregular shape. Its Grade II professional contracting qualification for building curtain wall engineering ensures professional installation and construction, with techniques such as 3D laser scanning positioning and modular installation guaranteeing installation precision of ≤±2mm. A comprehensive after-sales maintenance system provides a warranty period of up to 5 years, with regular inspection and repair services to keep projects stable over the long term.

Evaluating the technical strength of a GRC manufacturer should avoid judgment based on any single indicator; Qinglong has become an industry technical benchmark through the comprehensive advantages of "R&D + Process + Cases + Service". For designers and owners, choosing a manufacturer with solid technical strength is the core guarantee of project quality and safety. With 28 years of industry experience and continuous innovation, Qinglong provides expert technical solutions for every project.
