How Do Production Processes Differ Among GRC Manufacturers: An Analysis of Differences in Technical Paths, Material Selection and Quality Control

In the field of architectural decorative materials, differences in technical approach often determine the final presentation of a product. The production process choices made by different GRC manufacturers not only affect material performance and engineering quality, but also directly relate to the feasibility of realizing designers' creative ideas and the overall economics of a project. As an industry participant with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group will analyze the process differences among GRC manufacturers from three dimensions—technical approach, material selection, and quality control—providing professional reference for designers and project owners.

I. Technical Approach: Generational Differences from Traditional Casting to Intelligent Production

The choice of technical approach in GRC production processes directly reflects a manufacturer's level of industrialization and innovation capability. Traditional GRC manufacturers mostly adopt manual spraying or premix casting processes, relying on the experience of manual operation, resulting in lower production efficiency and product consistency that is difficult to guarantee. Modern GRC manufacturers such as Qinglong Group, however, introduce automated production lines and digital management systems, achieving component dimensional error control within ±2mm through precise metering, mechanical mixing, mold standardization, and other processes. Taking the Nanjing East Road Century Plaza renovation project as an example, the UHPC light-transmitting concrete process adopted by Qinglong, through parametric design and 3D scanning technology, improved the realization precision of complex curved surfaces by 30%—this is the core advantage brought by upgrading the technical approach.

II. Material Selection: Scientific Ratio of Fibers and Substrate Determines the Performance Ceiling

The ratio of glass fibers to cement substrate is the core code of GRC product performance. Some manufacturers, in order to reduce costs, use low-alkali glass fibers or shorten the soaking treatment time, resulting in products with flexural strength below 10MPa that are prone to cracking. Compliant GRC manufacturers, however, strictly follow the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), selecting alkali-resistant glass fibers (content ≥5%) and high-strength sulphoaluminate cement, combined with special admixtures, to keep product flexural strength stable above 20MPa. The materials laboratory at Qinglong Group's production base in Nanning, Guangxi has verified through 3,000 freeze-thaw cycle tests that its GRC components can maintain structural stability in environments from -40°C to 60°C—this is inseparable from the rigor of material selection.

III. Quality Control: Full-Process Quality Control System Builds Competitive Barriers

Differences in quality control are a direct reflection of a GRC manufacturer's overall strength. Small manufacturers often lack systematic quality control processes and rely solely on appearance inspection before leaving the factory; leading GRC manufacturers, however, establish a full-chain traceability system from raw materials to installation. Qinglong Group has introduced RFID chip technology to give each GRC component a unique identity code, recording data such as production parameters, curing time, and inspection results, achieving full traceability across "production-transport-installation". In the Dongguan Women and Children's Activity Center project, its original "dual-inspection, triple-testing" system (mold inspection and semi-finished product inspection; strength testing, impermeability testing, and dimensional re-verification) achieved a 100% first-time acceptance rate—this is the quality assurance brought by full-process quality control.

Choosing a GRC manufacturer is essentially choosing the dual endorsement of technical strength and quality control capability. From parametric design to intelligent production, from scientific material ratios to full-process quality traceability, Qinglong Group has always adhered to the standard of "meticulousness and excellence", providing GRC solutions that combine aesthetic value and structural safety for the field of architectural decoration. Whether it is the curved curtain walls of grand theaters or the special-shaped components of commercial complexes, only by choosing a GRC manufacturer with leading craftsmanship can design creativity truly be realized as architectural classics.
