How to Achieve Integration of UHPC Shaping with Metal Components: Technical Approaches and Engineering Applications

As architectural aesthetics and structural performance seek balance in the collision between metal and concrete, the combination of UHPC (Ultra-High Performance Concrete) and metal components is becoming a major breakthrough in contemporary architectural innovation. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group has leveraged its full-chain technical capabilities to accumulate extensive solution experience in this interdisciplinary field, creating building envelope systems for designers and owners that combine artistic expressiveness with engineering reliability.

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

With its ultra-high strength (compressive strength up to 150-200 MPa), excellent durability, and design freedom, UHPC complements the mechanical properties of metal materials. Through technical practice, Qinglong has explored three core integration approaches: first, mechanical anchoring connections, where embedded stainless steel connectors achieve rigid fixation between UHPC components and metal frames—a process successfully applied in an 8-meter-span UHPC sunshade system for a landmark project in Nanning; second, composite casting, where metal skeletons serve as internal support cast simultaneously with UHPC, leveraging UHPC's rheological properties to achieve one-time forming of complex curved surfaces, such as the double-curved curtain wall units of a commercial complex in Guangzhou; third, chemical bonding enhancement, which adopts custom modified epoxy resin systems to increase the interfacial bond strength between UHPC and metal by 40%, resolving the stress concentration issues of traditional connection methods.

Innovative Applications in Engineering Scenarios: From Aesthetic Expression to Underlying Logic

In actual projects, Qinglong advances the implementation of technical solutions through precise matching of material properties with architectural requirements. In a cultural center project in Shenzhen, a composite envelope of UHPC and aluminum alloy was adopted, with parametric design enabling seamless assembly of 1,200 irregularly shaped units—meeting the structural requirements of a 3.5-meter cantilever while achieving 0.5mm-level precision tolerance on UHPC surfaces through flatness control of the metal substrate. In the renovation of a historic building in Shanghai, UHPC precast components were innovatively combined with brass decorative lines, using UHPC's antique finishing techniques to replicate the metal decorative texture of the historic building while meeting modern structural safety standards.

Full-Chain Service Assurance: From Design Development to After-Sales Maintenance

As a national high-tech enterprise, Qinglong has established a full-process service system covering design, production, construction, and maintenance. During the design development stage, BIM technology and the Rhino parametric platform are used to simulate in advance the stress states of UHPC-to-metal connection nodes; the production stage employs automated production lines to keep component dimensional deviations within ±2mm; and the installation stage applies 3D laser scanning positioning technology to achieve millimeter-level precision assembly. To meet after-sales maintenance needs, Qinglong has developed an RFID chip-based full lifecycle traceability system for components, which, together with regular inspection and maintenance, ensures long-term stable system operation.

From envelope innovation in landmark buildings to detail refinement in commercial spaces, the combination of UHPC and metal components is reshaping the boundaries of architectural expression. Built on 28 years of technical accumulation, Qinglong Group will continue to explore more possibilities in composite material applications, providing designers with complete technical support from concept to implementation, allowing architectural beauty to radiate new vitality through the dual empowerment of technology and craftsmanship.
