Crafted with Ingenuity: The Complete Production Process of UHPC Exterior Wall Decorative Lines

UHPC (Ultra-High Performance Concrete) exterior wall decorative lines have become a preferred choice for high-end architectural decoration thanks to their high strength, high durability, and exquisite shapes. As a manufacturer with 28 years of experience in UHPC detailed design and production, Qinglong Group has developed a mature UHPC exterior wall decorative line manufacturing process through projects such as Fengjingwan in Nanning and Yangguang Madrid in Yangjiang, ensuring excellence in both product quality and decorative effect.

The production of UHPC exterior wall decorative lines involves multiple stages including design, materials, molds, production, and installation, with each step requiring precise control. Leveraging its full-chain service advantages, Qinglong integrates craftsmanship into every process detail to create decorative pieces that combine aesthetics with performance.

???? Detailed Design: Precisely Connecting Creativity with Implementation

Based on the architectural drawings, detailed design is carried out in line with the characteristics of UHPC materials to define the dimensions, shapes, wall thicknesses, and installation nodes of the lines. BIM technology is used for 3D modeling and clash detection to optimize structural rationality and avoid construction conflicts. In the Dongguan Women and Children's Activity Center project, Qinglong achieved the precise realization of complex curved decorative lines through parametric design, ensuring consistency with the building's overall style.

???? Mold Making: Ensuring Precise Shapes and Surface Texture

High-quality fiberglass-reinforced plastic or steel molds are selected and precisely machined according to the line shapes, with mold surface flatness deviation controlled within 2mm/m. For complex textures or relief patterns, silicone molds are used for fine replication to ensure faithful reproduction of the decorative effect. Qinglong's mold-making process achieves line shape deviations of ≤1mm and a mirror-grade surface finish, laying the foundation for subsequent forming.

⚙️ Batching and Mixing: Precise Proportioning to Ensure Material Performance

According to the dedicated formula ratios, cement, quartz sand, active mineral admixtures, steel fibers, admixtures, and water are fed into a forced-action mixer, with mixing time controlled at 5–8 minutes to ensure uniform mixing of materials and even fiber dispersion. Qinglong uses an automated batching system with a batching error of ≤±1%, ensuring stable strength and flowability of the UHPC material to meet casting and forming requirements.

????️ Casting and Curing: Careful Operation to Ensure Forming Quality

The uniformly mixed UHPC slurry is poured into the molds, with vibrating tables or manual auxiliary vibration used to ensure the slurry fills completely without trapped air bubbles. After casting, initial curing is performed, followed by high-temperature curing in a steam curing kiln, with temperature controlled at 60–80°C and a curing time of 3–5 days, allowing component strength to quickly reach the required standard. In the Kaiyin New Town project in Zhongshan, Qinglong's precise curing kept the compressive strength of the decorative lines consistently above 120MPa.

???? Finishing and Installation: Attention to Detail for a Perfect Presentation

Before leaving the factory, components undergo surface grinding and repair to remove burrs and defects, ensuring a flat and smooth surface. On-site installation is carried out using dry-hanging or adhesive bonding methods according to the installation node design, with laser levels controlling installation accuracy to within ≤2mm. In the Nanhu Mingdu project in Nanning, Qinglong achieved seamless connections of the decorative lines through a standardized installation process, enhancing the overall aesthetic of the building facade.

The production of UHPC exterior wall decorative lines combines technology with craftsmanship, and every process step requires strict control. With its mature process system, advanced production equipment, and professional technical team, Qinglong Group provides full-process services from design to installation, delivering high-quality UHPC decorative lines for architectural projects. In the future, as the process continues to advance, UHPC decorative lines will shine in more high-end buildings.
