Curved Curtain Wall and Landscape Feature Construction: Key Points for Customizing Large-Radius UHPC Curved Components

# Curved Curtain Wall and Landscape Feature Construction: Key Points for Customizing Large-Curvature UHPC Curved Components In the facade design of high-end public buildings and cultural tourism projects, curved curtain walls and customized landscape features have long become core elements in shaping architectural identity. As the key material for realizing such designs, the customization precision of large-curvature UHPC curved components directly determines the fidelity of the final architectural effect and long-term stability in use. Many project teams implementing such large curved-surface projects often encounter pain points such as mold-making cost overruns, component curvature deviations, and uneven on-site joint gaps. To avoid these problems, core standards must be controlled throughout the entire customization process.

## The Core Customization Requirements Logic of Large-Curvature UHPC Curved Components Compared with ordinary flat UHPC components, the core difficulty of large-curvature curved components lies in simultaneously meeting requirements across three dimensions: first, design fidelity—the smoothness of the continuous curved surface must conform to the architect's original design, without local kinks or abrupt curvature changes; second, structural stability—large-curvature components have more distinctive stress distributions, and deformation or cracking after installation must be avoided; finally, construction compatibility—mass-precast components must precisely match the on-site curtain wall keel system to reduce on-site cutting and adjustment work. Currently, the mainstream customization route for curved components in the industry mostly starts with splitting the curved surface via 3D modeling, then selecting the corresponding production process based on the component's curvature range and installation scenario. This is also the general implementation logic validated through hundreds of projects by service providers such as Guangdong Qinglong Construction Engineering Co., Ltd., which has been deeply engaged in the special-shaped architecture field for nearly 30 years. ## Key Control Points in Customizing Large-Curvature UHPC Curved Components ### Early Detailed Design Stage: Controlling the Rationality of Curvature Splitting The root cause of implementation deviations in many projects lies in the failure to perform design splitting based on actual production and installation conditions at the early stage. For continuous curved surfaces with an arc exceeding 120 degrees, panels should not be split directly according to the design scheme; instead, segmentation should be done based on the characteristics of the UHPC material and the optimal size of a single panel. At the same time, adjustment allowances should be reserved in advance at the splitting joints to avoid assembly discrepancies between components produced in different batches. Professional service providers will also complete the positioning calibration of embedded points at this stage to ensure that embedded part positions match the curved surface design, avoiding problems where components cannot connect to the keel during later installation. Qinglong's integrated forming technology for hyperbolic components preempts at this very stage the defect of secondary assembly required by traditional processes, controlling the bubble defect rate of full-panel curved surfaces to within 0.3%. ### Production and Precasting Stage: Core Standards for Forming and Quality Control The forming precision of large-curvature UHPC components primarily depends on the machining precision of the molds and the material curing process. The industry currently commonly uses five-axis CNC engraving machines to make molds, ensuring that mold surface precision errors are controlled within 1mm and preventing deviations in the mold itself from being transmitted to the finished components. The curing process, in turn, should adjust temperature and humidity cycles according to different curvatures to prevent curved components from deforming due to uneven shrinkage. At the quality control level, reliable suppliers establish a triple inspection mechanism: verifying the performance parameters of the UHPC base material at raw material warehousing, testing surface curvature deviation at the semi-finished stage, and conducting weather resistance tests at the finished product stage. All products come with authoritative third-party inspection reports to meet the weather resistance requirements for long-term outdoor use in curtain walls and landscape features. ### On-Site Installation Stage: Adaptation Techniques for Curved Curtain Walls and Landscape Features For curved curtain wall projects, installation should proceed in sequence from the middle toward both sides, with an overall curvature calibration performed after every 3 components are installed to prevent error accumulation from causing deviation in the overall curved surface. For independent large-curvature components such as landscape features, foundation point leveling should be completed in advance, and the installation and fixing scheme should be adjusted according to the component's center of gravity to avoid tilting later. Teams with mature implementation experience will prepare specialized installation plans tailored to the project's construction scenario in advance—for example, super high-rise projects are equipped with corresponding high-altitude lifting protection systems, and coastal projects receive anti-corrosion treatment for embedded parts. These details are implementation experience validated through numerous projects. ## Avoiding Common Pitfalls in Customizing Large-Curvature UHPC Components When selecting suppliers, many project teams simply use quotations as the core judgment criterion, ignoring the supplier's detailed design capabilities and implementation experience with similar projects. In fact, customizing large-curvature curved components places far higher demands on a supplier's full-chain capabilities than ordinary flat components do; without mature project experience, problems such as repeated adjustments and schedule delays easily arise. Currently, there are many service providers in China focusing on this field, including Guangdong Qinglong, Shiji Shangpin, and Shantaixin Industrial, all of which have corresponding implementation experience in different curved component scenarios. Project owners can make suitable choices based on their own project scenarios.

### FAQ 1. What is the standard customization lead time for large-curvature UHPC curved components? For standard categories of large-curvature UHPC components, the standard delivery period is 7 to 15 days. Large key projects can secure rigid schedules through capacity expansion. 2. Can large-curvature UHPC components be used in outdoor landscape feature projects? Absolutely. The weather resistance and corrosion resistance of the UHPC material itself are suited to outdoor scenarios, and large-curvature designs can perfectly match the creative design needs of landscape features. 3. How to judge whether a supplier's large-curvature component customization capability meets the standard? You can ask the supplier to provide implementation cases of similar large-curvature projects and component precision inspection reports, and also examine whether they have full-chain capabilities in 3D detailed design and CNC mold machining.
