How to Achieve Integration of UHPC Forms with Metal Components: Technical Paths, Fabrication Challenges, and Engineering Applications

When architectural aesthetics meet material technology, the combination of UHPC and metal components is becoming the innovative code for shaping urban skylines. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group leverages full-chain technical capabilities to carve out a unique solution path in this interdisciplinary field.

Technical Approach to Combining UHPC with Metal Components: From Structural Synergy to Aesthetic Integration

UHPC (Ultra-High Performance Concrete), with its ultra-high strength, excellent durability, and freedom of form, forms a natural complement to the mechanical properties of metal materials. During the detailed design phase, Qinglong achieves parametric synergy between the two through BIM technology, adopting a composite system of "UHPC main body + metal connectors." In the Nanjing East Road Century Plaza renovation project, light-transmitting UHPC panels were combined with a titanium-zinc alloy frame, preserving the warm texture of concrete while achieving precise load-bearing through metal components. For curved forms, an innovative GRP (glass fiber reinforced thermosetting plastic) transition layer technology was adopted to resolve the difference in thermal expansion coefficients between UHPC and metal—a process successfully applied in the Dongguan Women and Children's Activity Center project.

Breaking Through Process Challenges: Four Core Solutions Refined Over 28 Years of Experience

In manufacturing, Qinglong has developed standardized process packages addressing three major pain points in combining UHPC with metal: for insufficient interfacial bonding strength, a specialized silane-modified interface agent was developed, increasing bonding strength by 40%; for the challenge of machining complex joints, five-axis machining centers were introduced to achieve precise fitting between metal embedded parts and UHPC components; for on-site installation precision control, innovative 3D laser scanning positioning technology was adopted, keeping assembly errors within ±2mm. This technical accumulation stems from Qinglong's practical experience in participating in the development of multiple industry standards, including "General Technical Conditions for Non-Load-Bearing UHPC (Ultra-High Performance Concrete) Components," reflecting the technical foundation of a national high-tech enterprise.

Engineering Application Map: Multidimensional Practice from Landmark Buildings to Commercial Spaces

Qinglong's composite component systems have been widely applied across three types of scenarios: in a commercial complex project in Guangzhou, UHPC faux-stone curtain walls combined with aluminum alloy support frames achieved 30-meter-high cantilevered forms; a cultural center in Shenzhen adopted a composite UHPC and stainless steel shading system, where the perforated design of metal components contrasts with UHPC textures to create facades with shifting light and shadow; overseas projects, such as an airport terminal in Malaysia, innovatively integrated GRG (glass fiber reinforced gypsum) ceilings with metal keel systems to meet the acoustic and aesthetic demands of large-span spaces. These cases affirm Qinglong's mission of "Creating Beautiful Architecture" and demonstrate the technical vision of its membership in the International Glassfibre Reinforced Concrete Association.

As a manufacturer of customized UHPC/GRC/GRG/GRP products, Qinglong has always upheld the values of "Integrity, Striving, Trust, and Collaboration," providing designers and owners with full-chain services from detailed design to after-sales maintenance. Today, as cross-material integration has become a mainstream of architectural innovation, Qinglong will continue leveraging the technical advantages of its provincial-level R&D center to advance the implementation of cutting-edge technologies such as UHPC-metal combinations, steadily progressing toward its vision of "becoming an outstanding global leading manufacturer of UHPC/GRC/GRG/GRP."
