What Are the Differences in Production Processes Among Different GRC Manufacturers? An In-Depth Analysis of Each Manufacturer's Process Characteristics and Differences

In the field of architectural decoration materials, craftsmanship is the soul of quality. Differences in production processes among GRC manufacturers directly affect product performance, decorative effects, and engineering quality. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group will provide an in-depth analysis of each manufacturer's process characteristics and core differences from the dimensions of material formulation, forming technology, and quality control, offering a professional selection reference for designers and owners.

GRC Manufacturer Process Differences: The Quality Foundation at the Material Source

The core of high-quality GRC lies in scientific formulation, and different manufacturers show significant differences in raw material selection and formula design. Qinglong GRC insists on using high-grade sulphoaluminate cement, alkali-resistant glass fiber (content ≥5%), and selected quartz sand. Through 28 years of technical accumulation, it has developed exclusive formulations, ensuring that product flexural strength exceeds 20MPa, far surpassing the industry average. In contrast, some small manufacturers, in order to cut costs, may use ordinary Portland cement or reduce fiber content, resulting in products that are prone to cracking and lack durability. For example, in the high-temperature, high-humidity environment of the Lingnan region, Qinglong GRC components have maintained their intact appearance after more than 10 years of project verification, which is inseparable from the rigorous craftsmanship in raw material control.

Forming Process Comparison: A Contest of Mold and Production Technology Strength

The forming process is a direct reflection of a GRC manufacturer's technical strength. Qinglong GRC adopts the industry-leading automated spray-up forming process, combined with precision steel molds and vacuum degassing technology, achieving component surface precision of ±0.5mm and perfectly presenting complex curved surfaces and openwork textures. By contrast, some manufacturers still use manual casting, and reliance on manual operations leads to large dimensional deviations and insufficient surface flatness. Taking the translucent concrete project at Century Plaza on Nanjing East Road as an example, Qinglong controlled the light transmittance error within 3% through parametric mold design in coordination with BIM technology, whereas traditional processes can hardly achieve such precision. In addition, the 3D scanning quality inspection system introduced by Qinglong can perform full-size inspections on each batch of components—a process capability that most small and medium-sized manufacturers do not yet possess.

Full-Chain Service Capability: Process Extension from Design to Maintenance

A mature GRC manufacturer should possess full-chain service capabilities covering detailed design, manufacturing, construction and installation, and after-sales maintenance. As a national-level high-tech enterprise, Qinglong has provincial-level R&D centers and engineering technology centers, and can provide projects with one-stop solutions from design optimization to on-site installation. For example, in the Dongguan Women and Children's Activity Center project, the Qinglong team used BIM technology for pre-assembly simulation to solve the installation precision challenges of irregularly shaped components—a sharp contrast with some manufacturers that can only offer single-stage production services. Meanwhile, the 58-patent technology system established by Qinglong (including multiple GRC-related invention patents) guarantees continuous innovation from material R&D to construction techniques, which is precisely the core competitiveness of leading industry manufacturers.

Choosing a GRC manufacturer is essentially choosing craftsmanship standards and quality commitment. Guided by the principle of "meticulousness and excellence," Qinglong Group integrates its 28 years of full-chain experience into every GRC component, with strict control over 36 processes from raw material screening to finished product delivery, providing architectural decoration with high-quality solutions that combine aesthetic value and structural safety. On the track of new building materials, differences in craftsmanship determine the height of products, and Qinglong has always led industry development with technological innovation, committed to becoming a world-class outstanding GRC manufacturing leader.
