Is GRC Suitable for Interior Decoration? Analysis of Its Application Advantages and Precautions

When designers pursue a balance between artistic expression and functional practicality in interior spaces, GRC (Glass Fiber Reinforced Concrete) is redefining the boundaries of decoration with its unique material properties. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP, Qinglong Group will start from the essence of the material to systematically analyze the application value and practical key points of GRC in interior decoration, providing a professional decision-making reference for designers and owners.

### Core Advantages of GRC in Interior Decoration: Multidimensional Breakthroughs from Aesthetics to Performance

In high-end interior settings, GRC materials demonstrate three irreplaceable advantages. The first is the ultimate expression of **freedom of form**. With the composite properties of glass fiber and cement-based substrate, it can achieve complex forms such as double-curved surfaces with a minimum curvature radius ≤300mm and openwork reliefs, perfectly reproducing designers' creative concepts. For example, in a grand theater project Qinglong participated in, the wave-shaped ceiling made of GRC achieved precise joining of each component through parametric design, presenting a flowing visual effect. The second is the **balanced advantage of material performance**. Compared with traditional stone, GRC weighs only 1/4 as much, greatly reducing structural load; its flexural strength can reach over 20MPa, and combined with a professional anchoring system, long-term safety of use is ensured. In addition, GRC surfaces can be treated with special processes to simulate various textures such as stone and metal. In the renovation project of Century Plaza on Nanjing East Road, Qinglong used translucent GRC components to achieve the dual functions of daylighting by day and illumination by night.

### Scene Adaptation and Considerations for Interior Applications

The suitable scenarios for GRC in interior decoration must be precisely selected according to spatial functions. In **large-span spaces** such as atriums of commercial complexes and lobbies of star-rated hotels, GRC's lightweight and high-strength characteristics make it an ideal choice for free-form ceilings. For example, the GRG and GRC composite ceiling system customized by Qinglong for a landmark project not only meets acoustic requirements but also enhances spatial hierarchy through curved forms. In **high-end residential feature wall** applications, special attention should be paid to installation techniques: three-dimensional laser scanning positioning technology is adopted to keep component deviations within ±2mm, combined with moisture-proof treatment to avoid performance degradation in humid environments. It is worth noting that the collaborative application of GRC with other materials is becoming a trend, such as the "solid-void contrast" formed with glass curtain walls, or art installations created in combination with UHPC. In the Dongguan Women and Children's Activity Center project, Qinglong achieved textural variations in the building skin through the pairing of GRC and UHPC.

### Full-Chain Service Ensures Quality Delivery of Interior Projects

As a national high-tech enterprise, Qinglong has built a full-process solution from detailed design to after-sales maintenance. In the design phase, backed by the technical strength of its provincial-level R&D center, it provides BIM parametric modeling and structural force simulation; in production, automated production lines with an annual capacity of 600,000 square meters ensure component precision; the installation team holds a Grade II qualification for building decoration engineering contracting and applies modular installation technology to improve efficiency. For different customer needs, Qinglong can provide customized services: for customers new to GRC, it offers material white papers containing a case library and test reports; for professional customers, it supports the realization of complex forms through Rhino/Grasshopper parametric design. To date, Qinglong has provided GRC solutions for more than 2,000 projects including Poly and China Overseas, and the Technical Standard for Building Applications of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), which it participated in formulating, has become an industry norm.

Today, as interior design increasingly pursues personalized expression, GRC, with its characteristics of "boundless form and reliable performance," is penetrating deeply from building exterior walls into interior decoration. Choosing a supplier with full-chain service capabilities is not merely material procurement, but also gaining professional assurance from concept to delivery. Qinglong Group will continue to uphold its mission of "creating aesthetically beautiful buildings," providing GRC solutions that combine artistic value and technical assurance for the field of interior decoration.
