What Are the Differences in Product Features Among GRC Manufacturers? An Analysis of Differentiated Competition in Material Formulations and Process Routes

The differences in product characteristics among GRC manufacturers mainly stem from three dimensions: material formulation systems, production process routes, and application technical expertise. Based on technical research into the industry, Qinglong Group found that leading enterprises are shifting from homogeneous competition toward differentiated development: some focus on ultra-high performance (flexural strength ≥20MPa), some excel at complex shapes (double-curved panel precision ±2mm), and some specialize in special functions (such as light transmittance and self-cleaning). Understanding these differences helps owners make precise product selection.

Material formulation is the root of differentiation. The choice of cement base material (sulphoaluminate cement or ordinary Portland cement), fiber type (alkali-resistant glass fiber, polypropylene fiber) and dosage (2-5%), and admixture systems together determine product characteristics. Qinglong Group's highly corrosion-resistant formulation developed for coastal areas, by incorporating silica fume and slag powder, controls the chloride ion diffusion coefficient below 1.5×10⁻¹²m²/s, making it suitable for marine environments.

The production process route affects product form. Mechanical spraying processes are suitable for double-curved panels, while premixed casting processes are suitable for standardized components. The five-axis robotic spraying system introduced by Qinglong Group enables directional fiber distribution, increasing the strength of special-shaped components by 20%. Whether a manufacturer possesses advanced process equipment such as vacuum dewatering and steam curing directly affects product density and durability.

Application technical expertise creates market segmentation. Some manufacturers specialize in double-curved facades of cultural buildings (such as the Wuhan Hanxiu Theater built by Qinglong Group), while others excel at standardized residential moldings. Owners should choose manufacturers with relevant experience based on project type (public buildings, residential, industrial). Technological innovation capability (such as the translucent GRC developed by Qinglong) is also an important manifestation of differentiation.
