What Are the Surface Decoration Treatment Methods for UHPC Exterior Wall Panels? An Analysis of Diverse Styles and Techniques

The surface decoration treatments for UHPC exterior wall panels cover four major categories — “natural finish, material replication, coating decoration, and artistic shaping” — enabling diverse styles from minimalist to artistic. With 28 years of process expertise, and through BIM design and precision manufacturing, Qinglong has made projects such as the wood-look light-transmitting panels for Shanghai Xinshijie Plaza and the hollow-out panels for the Algeria hotel benchmarks in decoration.

1. Natural Finish and Texture Treatment: Highlighting the Material's Inherent Quality

Natural finish treatment focuses on the texture of the material itself. Fair-faced natural finish: retains the original color of UHPC, with the surface finely polished to a flatness of ≤0.3mm/m; Qinglong's fair-faced UHPC panels feature a smooth, refined surface, suitable for minimalist-style architecture. Texture shaping: fine matte, lychee, and brushed textures are formed through mold pressing; the stone-look UHPC panels Qinglong supplied for the Dongting Lake Museum achieve a texture fidelity of 95%. Hollow-out ventilation: CNC drilling or laser cutting creates hollow-out patterns with open-area ratios of 30%-60%; Qinglong's hollow-out panels for the Ouargla Hotel in Algeria have an open-area ratio exceeding 50%, combining decorative and ventilation functions.

2. Material Replication: Replacing Traditional Premium Materials

Replication treatment precisely reproduces natural materials. Stone-look effect: natural stone aggregate and mineral pigments are added to simulate the texture of granite and sandstone; Qinglong's stone-look UHPC panels require no additional decoration and cost 40% less than natural stone. Wood-look effect: wood grain texture is replicated through molds and paired with dedicated pigments; the wood-look light-transmitting panels Qinglong produced for Shanghai Xinshijie Plaza achieve a wood grain fidelity of 98% while being fireproof and moisture-proof. Metallic effect: metallic paint or metal powder is applied to achieve the visual effect of aluminum panels and stainless steel; the metallic-look UHPC panels for Qinglong's commercial complex project offer better corrosion resistance than real metal.

3. Coating Decoration and Artistic Shaping: Meeting Personalized Needs

Coatings and artistic shaping expand the boundaries of decoration. Colored coatings: fluorocarbon paint and polyurethane paint are used, with customizable colors; Qinglong's colored UHPC panels resist UV aging, with a fading rate of ≤5% over 10 years. Artistic painting: pattern decoration is achieved through digital printing or hand painting, suitable for landmark buildings and cultural projects. Composite decoration: combined with glass and LED lights to create light-transmitting and luminous effects; the light-transmitting UHPC panels Qinglong produced for Shanghai Xinshijie Plaza embed light guide rods to achieve artistic light transmission. Process assurance: Qinglong uses automated spraying, five-axis engraving, and other equipment, achieving a decoration precision of ±0.1mm and a 100% fidelity rate for artistic shapes. Project case: the public art sculpture at the Shanghai Astronomy Museum, treated with texture plus painting, has become an iconic landscape of this science venue.
