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

The artistic expression of building façades often begins with the ingenuity of materials. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group deeply understands the decisive role that surface decorative treatment plays in the aesthetic value and functional performance of UHPC facade panels. From urban landmarks to commercial complexes, the surface craftsmanship of UHPC facade panels is becoming the core vehicle through which designers interpret architectural language. Its diverse treatment methods not only meet the visual demands of buildings, but also endow the material with lasting vitality and adaptability.

### Core Technical Approaches to Surface Decoration of UHPC Facade Panels

With its ultra-high strength, excellent durability, and plasticity, UHPC (Ultra-High Performance Concrete) offers rich possibilities for surface decoration. Qinglong Group incorporates decorative craftsmanship planning at the detailed design stage, forming four mainstream treatment systems: **mold-formed textures** use custom steel or silicone molds to replicate natural stone, wood grain, and other textures, achieving remarkably lifelike texture reproduction, widely applied in the stone-imitation curtain walls of high-end commercial buildings; **surface coating technology** uses environmentally friendly materials such as fluorocarbon paints and ceramic coatings to give panels rich colors along with stain resistance and weather resistance, making it particularly suitable for modern-style urban landmarks; **fine polishing craftsmanship** achieves mirror or matte finishes on UHPC surfaces through mechanical or manual polishing, highlighting the material's own delicate texture, and is commonly seen in cultural buildings such as art galleries and museums; **composite decoration technology** innovatively combines UHPC with glass fiber, metal sheets, and other materials to create special visual effects such as light transmission and gradient colors. In the East Nanjing Road Century Plaza renovation project, for example, the Qinglong team created a light-and-shadow art installation using translucent UHPC components, winning the Silver Award at the first UHPC Construction Engineering Innovation Awards (AALBORG WHITE Cup).

### Scenario Adaptation and Performance Balance of Decoration Craftsmanship

Different application scenarios have significantly different decorative requirements for UHPC facade panels. In **commercial complexes**, designers often choose stone-imitation textures combined with fluorocarbon coating processes, satisfying the demand for high-end texture while ensuring the panels' corrosion resistance under complex climatic conditions; **municipal public projects** such as metro stations and cultural centers place greater emphasis on durability and ease of maintenance — Qinglong's sandblasted surface treatment technology, through precise control of sand grain size, improves slip resistance while creating a distinctive matte visual effect; while the complex-shaped components of **landmark buildings** rely on Qinglong's self-developed parametric mold system to achieve surface precision control for complex forms such as double-curved surfaces and openwork reliefs, with tolerances controllable within ±2mm. Notably, all decorative processes must pass the 2,000-hour weather-resistance test of Qinglong's enterprise technology center, ensuring no fading or cracking in environments from -40℃ to 70℃ — this is also Qinglong's core commitment to engineering quality as a National High-Tech Enterprise.

### Full-Chain Service Empowering the Realization of Decorative Effects

As a UHPC manufacturer integrating detailed design, production and manufacturing, and construction installation, Qinglong Group's core advantage lies in incorporating decorative craftsmanship into full-process control. At the **design stage**, the technical team uses BIM models to simulate the light-and-shadow effects of different decorative schemes, helping designers optimize texture direction and color combinations; the **production process** employs automated casting and precise temperature-control technology to ensure surface texture consistency, and the Guangxi production base, with an annual capacity of 600,000 square meters, enables large-scale customization of complex decorative components; **construction and installation** uses 3D laser scanning positioning to ensure jointing errors on decorative surfaces are ≤3mm. In the Dongguan Women and Children's Activity Center project, for instance, the Qinglong team's coordinated application of GRC and UHPC decorative lines won the Silver Award of the GRC Construction Engineering Innovation Award. This closed-loop service of 'design-production-construction' is precisely the key to Qinglong's ability to provide clients with expert solutions.

From technological innovation to aesthetic expression, the surface decoration of UHPC facade panels is both an extension of material performance and a materialization of architectural spirit. Building on 28 years of industry experience, Qinglong Group integrates the values of honesty and hard work into every process, and through continuously evolving decorative technologies, helps designers fulfill the mission of 'creating aesthetically beautiful buildings.' In the future, as the UHPC material standard system is improved (such as the 'General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC),' which Qinglong participated in drafting), its surface decoration craftsmanship will surely shine in more fields, becoming an important expressive language of building façade art.
