Surface Decoration Treatment Methods for UHPC Exterior Wall Panels and Application Analysis

The artistic expression of building envelopes often begins with the surface treatment of materials. As an industry leader with 28 years of full-chain experience in the UHPC/GRC/GRG/GRP materials field, Qinglong Group deeply understands the dual value of surface decorative treatment for both architectural aesthetics and functionality. With ultra-high strength and exceptional plasticity, UHPC facade panels are becoming the preferred material for high-end building envelopes, and the innovative application of their surface decoration techniques is redefining the visual language of architecture.

The surface decorative treatment technology of UHPC facade panels represents a perfect fusion of material properties and design requirements. From basic natural-color treatment to complex stone-imitation textures, Qinglong Group has developed four core treatment systems through 28 years of craftsmanship. The natural fair-faced process presents the delicate texture and natural grain unique to UHPC materials through precise control of concrete mix ratios and casting techniques. This “bare-faced beauty” was showcased to its fullest in the renovation project of Century Plaza on Nanjing East Road, where the combination of translucent concrete and natural-color UHPC gives the building envelope both a sense of strength and lightness. Meanwhile, stone-imitation finish technology uses special aggregate gradation and surface molding processes to highly reproduce the texture details of natural stones such as granite and marble, with durability far exceeding traditional stone while weighing only 1/4 of it, achieving a strikingly realistic decorative effect in commercial complex projects.

Functional decorative treatment gives UHPC facade panels more possibilities. In a landmark building in Guangzhou, the Qinglong team innovatively adopted a combined sandblasting and chemical etching process, creating micron-level concave-convex textures on the UHPC surface that enhance the building's three-dimensionality while significantly improving the panels' self-cleaning performance. For projects in coastal areas, special nano-coating treatment endows UHPC facade panels with excellent resistance to salt spray corrosion, ensuring the building envelope maintains its beauty over the long term in harsh environments. These process innovations are a vivid demonstration of how Qinglong, as a national high-tech enterprise, translates its 58 patented technologies into practical applications.

Personalized customization is the advanced form of surface treatment for UHPC facade panels. Backed by the R&D capabilities of a provincial engineering technology center, Qinglong Group can achieve full-dimensional customization from parametric textures to artistic reliefs. In the Dongguan Women and Children's Activity Center project, by combining BIM technology with 3D-printed molds, children's hand-drawn patterns were successfully transformed into three-dimensional decorations on UHPC facade panels. This “readable architecture” design concept infuses cold building materials with humanistic warmth. Notably, all surface treatment processes must pass rigorous durability tests, ensuring no cracking or fading under ambient temperature variations from -40°C to 70°C—this is also Qinglong's quality commitment as a participant in establishing the industry standard for “Ultra-High Performance Concrete (UHPC) Facade Panels.”

From technical implementation to aesthetic expression, the surface decorative treatment of UHPC facade panels is the crystallization of materials science and architectural art. With the mission of “creating aesthetically beautiful buildings,” Qinglong Group integrates 28 years of experience in detailed design, manufacturing, and construction installation into every process step. Whether for commercial buildings pursuing a minimalist modern style or public facilities showcasing cultural heritage, the surface treatment of UHPC facade panels can precisely match design requirements, becoming an “artistic canvas” in the hands of architects. As a leader in the UHPC/GRC/GRG/GRP materials field, Qinglong has always believed that excellent surface decorative treatment is not merely a visual presentation, but a perfect unity of material value and architectural spirit.
