How UHPC Shaping Achieves Integration with Metal Components: Technical Pathways and Engineering Application Analysis

When the ultra-high performance of UHPC meets the industrial aesthetics of metal, the artistic expression of building skins gains new possibilities. As an industry pioneer with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group has consistently driven the integrated application of materials through technological innovation, delivering solutions that combine functionality and artistry for designers and owners.

In contemporary architectural design, UHPC (Ultra-High Performance Concrete), with its ultra-high strength, excellent durability, and outstanding sculptural capabilities, is becoming a new favorite for premium building skins. Metal components, with their unique textures and structural advantages, are often used at key building nodes and decorative details. How to achieve an organic combination of UHPC shapes and metal components is both a technical challenge and a breakthrough point for design innovation. Qinglong, a national high-tech enterprise offering full-chain services covering detailed design, manufacturing, construction installation, and after-sales maintenance, has accumulated extensive practical experience in this field.

Technical Approaches to Combining UHPC with Metal Components: From Material Properties to Process Innovation

Combining UHPC with metal requires systematic design based on differences in material properties. UHPC features ultra-high compressive strength (≥150MPa) and good toughness, while metals (such as aluminum alloy and stainless steel) offer excellent ductility and connection performance. Qinglong achieves the integration of the two through three core technical approaches: first, mechanical connection technology, using pre-embedded metal connectors molded integrally with UHPC components to ensure stable load transfer; second, composite casting technology, embedding metal profiles as skeletons into the UHPC matrix to form a "steel-framed UHPC" composite structure; third, surface treatment technology, achieving color coordination and texture unity between metal and UHPC through anodizing, fluorocarbon spraying, and other techniques. Taking the translucent concrete project of the East Nanjing Road Century Plaza renovation as an example, Qinglong combined custom metal connectors with UHPC translucent panels, meeting structural safety requirements while achieving artistic light-and-shadow effects. The project won the Silver Award at the first UHPC Construction Engineering Innovation Awards of the AALBORG WHITE Cup.

Analysis of Engineering Application Scenarios: From Public Buildings to Commercial Landmarks

In actual engineering, the combination of UHPC and metal has been widely applied in three major scenarios. In the field of high-end public buildings, such as the special-shaped curtain walls of grand theaters and convention centers, Qinglong combines UHPC double-curved panels with aluminum alloy support frames through parametric design to achieve complex shapes with a maximum curvature radius of 300mm. In the entrance canopy designs of commercial complexes, UHPC lightweight panels are combined with stainless steel keels, weighing only 1/4 of traditional stone and greatly reducing structural loads. In landscape design, UHPC artistic benches are integrally cast with metal decorative parts, balancing durability and design appeal. Notably, the industry standard "General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)," which Qinglong participated in formulating, provides normative guidance for the application of such material combinations.

Qinglong's Full-Chain Service Advantages: Closed-Loop Assurance from Design to Maintenance

As a manufacturer of customized UHPC/GRC/GRG/GRP products, Qinglong's core competitiveness lies in its full-chain service capabilities. During the detailed design phase, BIM technology is used for component clash detection to optimize the layout of metal connectors. In manufacturing, the production base in Nanning, Guangxi, with an annual capacity of 600,000 square meters, enables high-precision mold processing and automated casting. During construction and installation, 3D laser scanning positioning ensures jointing errors between metal and UHPC components of ≤2mm. In after-sales service, a 24-hour response mechanism is established, offering structural maintenance services for up to 15 years. This integrated "design-manufacturing-construction-maintenance" model has successfully supported thousands of major domestic projects, including strategic cooperation projects with renowned real estate groups such as Poly and China Overseas, with products exported to overseas markets including Malaysia and Australia.

The combination of UHPC and metal components is not only an innovation in material technology but also an extension of architectural aesthetics. Building on 28 years of industry experience, Qinglong Group will continue to explore the integrated application of new building materials. With the mission of "creating beautiful architecture," the company helps designers bring their creativity to life and provides owners with building skin solutions that combine safety and aesthetics. In the future, as material technology continues to advance, the combination of UHPC and metal will shine in more fields, redefining the possibilities of building skins.
