Can GRC Products Be Customized in Special Colors?

In the field of architectural decoration, the color expression of materials is often a key link in bringing design concepts to life. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group frequently receives client inquiries about custom special-color GRC products. In fact, GRC (Glass Fiber Reinforced Concrete), with its unique material properties, can not only achieve rich color effects but also meet diverse design needs ranging from classical to modern.

**Technical Pathways for Custom Special-Color GRC**
Color customization of GRC materials is mainly achieved through two technical approaches: one is adding inorganic pigments to the concrete substrate to achieve through-body coloring; the other is using surface coating processes to obtain higher-saturation or special-texture color effects. Qinglong Group uses imported German iron oxide pigments combined with its independently developed color proportioning system, achieving over 90% color reproduction within the CIE LAB color space to ensure color uniformity and weather resistance. Taking a cultural center project as an example, by adjusting pigment proportions and curing processes, the color value deviation of the design-required "terracotta red" was successfully controlled within the professional range of ΔE≤2, and color retention remained above 95% after 8,000 hours of artificial accelerated aging tests.

**Application Scenarios and Advantages of Special-Color GRC**
In actual projects, special-color GRC has been widely used for the surface decoration of landmark buildings. For example, a coastal theater project adopted gradient-blue GRC curtain wall panels, simulating the light and shadow of ocean waves through color transitions; a commercial complex used golden GRC components to create a light-luxury style entrance. Compared with traditional decorative materials, GRC offers three major advantages in color customization: first, controllable cost—special colors add only 5%-15% extra cost in mass production; second, flexible shaping, which can be perfectly combined with complex structures such as double-curved surfaces and openwork patterns; third, strong durability—GRC products colored with inorganic pigments have a service life of over 50 years, far exceeding paint-finish materials.

**Qinglong Group's Custom Service Capabilities**
As a national high-tech enterprise, Qinglong Group has established a full-process service system from color design to finished product delivery. The company employs professional color engineers who can perform precise color matching based on color cards, samples, or Pantone codes provided by clients, and confirm effects through 1:1 sampling. The production process adopts automated mixing systems and standardized curing processes to ensure color consistency in every batch. During project implementation, the company once customized a special off-white GRC ceiling for an overseas airport project, successfully solving the color uniformity challenge of long-span components by optimizing the cement-based formula and pigment dispersion technology, earning technical certification from the International GRC Association.

**Key Considerations for Special-Color Customization**
When customizing special-color GRC, clients should note the following points: first, provide clear color standards—physical color cards are recommended as references rather than electronic files; second, consider the building's environment—for example, alkali-resistant pigments should be selected in high-temperature and high-humidity regions; finally, plan the production schedule reasonably, as special-color products usually require an additional 3-5 days for color matching and testing. Qinglong Group recommends that clients communicate color schemes at the early stage of the project so that optimal solutions can be provided in combination with structural design and cost budgets.

With the growing demand for personalization in architectural design, special-color GRC is becoming an important vehicle for shaping architectural aesthetics. Qinglong Group will continue to leverage its 28 years of accumulated technical expertise, providing designers with broader space for color expression through material innovation and process upgrades, helping to fulfill its corporate mission of "creating aesthetically beautiful buildings." Whether it is retro brick-red European-style components or futuristic metallic curtain walls, GRC materials will inject a vibrant color soul into buildings with their unique customization capabilities.
