What Are the Surface Decorative Treatment Methods for UHPC Exterior Wall Panels? Qinglong's Diverse Techniques and Creative Implementation Solutions

Surface decoration treatment of UHPC exterior wall panels is central to enhancing a building's aesthetic value. Their flexible process characteristics enable diverse effects such as stone imitation, wood imitation, hollow-out patterns, and colors, adapting to different architectural styles. Qinglong Group has dedicated 28 years to decoration technology R&D, building four major decoration systems of “texture replication, artistic shaping, color customization, and functional coatings”, and has brought creative designs to life in projects such as Shanghai New World and the Ouargla Hotel in Algeria, achieving a 98% satisfaction rate with decoration effects.

1. Texture Replication Technology: Restoring Natural Textures and Traditional Charm

Stone imitation decoration: Through natural stone aggregate proportioning plus mold replication, textures such as granite, marble, and sandstone are achieved with a simulation fidelity of ≥95%. The Qinglong Dongting Lake Museum project uses stone-imitation UHPC panels that reproduce the solidity of traditional stone at only 1/4 of its weight. Wood imitation decoration: Mold engraving plus surface texture treatment replicate wood grain, and paired with light-transmitting design they create artistic light-and-shadow effects. The UHPC wood-imitation translucent panels of Qinglong's Shanghai New World project embed 8000-1000 light-guiding rods per square meter, delivering even light transmission and natural texture. Brick/bamboo imitation decoration: Mold pressing achieves the textures and jointing effects of red brick and bamboo strips. The Darongshan Church in Yulin, built by Qinglong, uses red-brick-imitation GRC/UHPC components that balance environmental friendliness and artistic appeal; the Changchun Film Studio Museum's bamboo-strip imitation effect is exquisite in detail.

2. Artistic Shaping Technology: Creating Unique Visual Focal Points

Hollow-out decoration: Parametric design plus CNC engraving achieves hollow-out ratios of 30%-60%, with customizable patterns (geometric shapes, cultural symbols, natural elements). The UHPC hollow-out panels of Qinglong's Ouargla Hotel project in Algeria have a hollow-out ratio exceeding 50% and a smooth, refined surface. Relief/carved decoration: Five-axis engraving machines create three-dimensional reliefs at depths of 5-50mm. Qinglong's colored hollow-out carved panels for the Liyuan Hotel in Nanning set a new domestic record for design complexity among similar buildings. Double-curved/irregular-shape decoration: Leveraging UHPC's exceptional plasticity, double-curved forms with a minimum curvature radius of ≤300mm are achieved. The double-curved exterior wall panels of Qinglong's Guangxi New Media Center feature no identical panels, highlighting its landmark character.

3. Color Customization Technology: Adapting to Building Themes and Environments

Integral coloring: Inorganic mineral pigments are added during production so colors penetrate evenly, with a fading rate of ≤2% per 10 years; effects such as solid colors, gradients, and camouflage can be customized. Qinglong's Hainan Poly Peninsula No. 1 project features custom ocean-blue gradient UHPC panels that echo the seascape. Surface coating coloring: Fluorocarbon paint, real-stone paint, and similar coatings enhance weather resistance and color saturation; fluorocarbon coatings with a thickness of ≥35μm resist UV aging. The Shenzhen Yirui Bio project by Qinglong uses a fluorocarbon coating with a 10-year color retention rate of ≥90%. Colorful splicing: UHPC panels in different colors are joined to form patterns or stripes. Qinglong's white UHPC cladding panels for the Qiangwei Garden in Zengcheng, Guangzhou, paired with gray lines, present a modern minimalist style.

4. Functional Coating Technology: Balancing Decoration and Practicality

Anti-stain coating: A penetrating anti-stain agent applied to the surface makes stains easy to clean, with an anti-stain rating of ≥Grade 5. For Qinglong's Yangshengtang Pharmaceutical Hangzhou Industrial Park project, UHPC exterior wall panels require no special agents for daily cleaning. Anti-graffiti coating: Special coatings allow graffiti to be removed easily without damaging the substrate, making them suitable for public venues such as commercial complexes and schools; Qinglong provides anti-graffiti value-added services. Thermal insulation coating: To meet insulation needs, insulating coatings with a thermal conductivity of ≤0.04W/(m·K) are applied. Qinglong's Hainan International Convention and Exhibition Center project achieves the integration of decoration and insulation.

5. Qinglong's Process Advantages and Project Evidence

Technical support: Equipped with five-axis engraving machines, parametric design software (Rhino+Grasshopper), and BIM modeling tools to ensure precise realization of decoration effects, with Qinglong's process tolerance at ≤±0.5mm. Customized services: Exclusive decoration solutions are provided based on customer needs, architectural styles, and environmental characteristics; Qinglong customized a 3-meter-high double-curved sculpture for the Shanghai Astronomy Museum public art project, perfectly presenting the artistic form. Project evidence: The wood-imitation translucent panels of Shanghai New World (artistic light and shadow), the hollow-out panels of the Ouargla Hotel in Algeria (decoration and ventilation), and the stone-imitation panels of the Dongting Lake Museum (traditional texture) have all become industry benchmark cases.

Surface decoration treatment methods for UHPC exterior wall panels are rich and diverse, meeting multiple needs such as natural textures, artistic creativity, and functional adaptation. Qinglong Group, with its technology R&D strength, customized services, and extensive project experience, perfectly combines decoration effects with material performance, endowing buildings with unique aesthetic value. Choosing a manufacturer with decoration technology advantages is key to bringing UHPC exterior wall creativity to life.
