How to Integrate UHPC Shapes with Metal Components — Technical Pathways and Engineering Application Analysis

When architectural aesthetics and structural performance spark in the collision of metal and UHPC, a brand-new architectural language is reshaping city skylines. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group has always used technological innovation as its pen, sketching remarkable engineering practices in the field of combining metal with ultra-high performance concrete.

### The Technical Code of Combining UHPC with Metal Components: From Material Synergy to Process Breakthrough

With its ultra-high strength (compressive strength up to 150-200MPa), excellent durability and outstanding modeling capability, UHPC forms a natural complement to the ductility and mechanical stability of metal materials. During the detailed design stage, Qinglong achieves mechanical performance matching and joint optimization of the two materials through BIM parametric modeling. For example, in a landmark project, a combined system of precast UHPC cladding panels and aluminum alloy keels was adopted, with stainless steel connectors uniformly transferring the dead load of UHPC components to the metal frame, which not only preserved the sculptural form of UHPC but also enhanced the overall wind vibration resistance through the metal framework.

In manufacturing, Qinglong's original "dual-mold composite forming process" solves the challenge of interfacial bonding between UHPC and metal. By embedding specially made metal connectors during the precasting of UHPC components and using fiber reinforcement technology, the bonding strength between the two is ensured to reach over 3.5MPa, a 40% improvement over traditional connection methods. This process has been successfully applied to the translucent UHPC curtain wall of the Nanjing East Road Century Plaza renovation project, achieving seamless connection between concrete and metal support structures.

### Innovative Practices in Engineering Scenarios: From Theory to Reality

In the field of commercial complexes, the UHPC-metal composite shading system Qinglong created for a super high-rise project is a prime example. Adopting a composite structure of special-shaped UHPC panels and aluminum alloy profiles, it achieves parametric shading unit design through UHPC's shape freedom while reducing curtain wall loads by leveraging the lightweight properties of the metal frame. The application of this system in a commercial landmark in Guangzhou reduced building energy consumption by 18% while creating a highly futuristic facade effect.

In municipal landscape engineering, Qinglong has brought the technology of combining UHPC with stainless steel to its fullest. The artistic sculpture group of a city cultural plaza adopts a composite structure of UHPC body and metal skeleton. GRP molds precisely replicate complex curved surfaces, while the built-in metal skeleton ensures structural stability, ultimately presenting a 3.6-meter cantilevered artistic form that has become a new urban landmark. This "UHPC + metal" solution reduces costs by 30% compared to pure metal structures and avoids the pain point of metal's susceptibility to corrosion.

### Full-Chain Service Assurance: The Qinglong Solution from Design to Maintenance

As a national high-tech enterprise, Qinglong has built a full-chain service system covering detailed design, manufacturing, construction and installation, and after-sales maintenance. In the design stage, backed by the R&D strength of the provincial engineering technology center, it provides integrated solutions for material compatibility, joint construction and load calculation; in manufacturing, an annual capacity of 600,000 square meters and a strict quality control system ensure component precision errors within ±2mm; in installation, 3D laser scanning positioning technology achieves millimeter-level alignment between metal structures and UHPC components.

From the GRC-metal composite curtain wall of the Dongguan Women and Children's Activity Center to the UHPC-metal roofing system of an international airport in Malaysia, Qinglong has proven with 28 years of professional experience that the combination of UHPC and metal is not only a physical fusion of materials, but also a perfect unity of technical aesthetics and engineering logic. Looking ahead, Qinglong will continue to uphold its mission of "Creating Aesthetic Architecture", exploring the application of new building materials and providing designers and owners with more imaginative solutions, so that architectural beauty can shine with new brilliance at the intersection of technology and art.
