Which Manufacturers Can Make UHPC Curtain Wall Panel Connections: Analysis of Mainstream Manufacturers and Technical Solutions

In the field of contemporary architectural decoration, UHPC curtain wall cladding panels have become the preferred material for high-end building envelope design thanks to their ultra-high strength, excellent durability, and rich expressive formability. The connection method, as a core factor affecting the safety and stability of curtain wall systems, has always been a focal point of industry attention. Currently, manufacturers capable of providing UHPC curtain wall cladding panel connection technical solutions fall mainly into two categories: one consists of specialized manufacturers focusing on UHPC material R&D and application, and the other consists of comprehensive building materials enterprises with full industry chain integration capabilities. As an industry player with 28 years of experience in detailed design, manufacturing, construction, and installation of UHPC/GRC/GRG/GRP materials, Qinglong Group will analyze the topic from two aspects—technical solution comparison and the characteristics of mainstream manufacturers—to provide professional reference for designers and building owners.

Mainstream UHPC curtain wall cladding panel connection technical solutions can be summarized into three major systems. The first is mechanical anchoring connection, which rigidly fixes the panels to the main structure through stainless steel bolts or embedded parts. This solution is suitable for high-rise curtain walls with heavier loads, offering the advantages of convenient installation and clear force transmission. Representative manufacturers such as Nanjing Beilida often adopt this technology in large-span curtain wall projects. The second is back-bolt connection, which uses special back bolts to fasten the panels from the rear, achieving an aesthetic effect with no visible connection points on the panel surface. Enterprises such as Guangdong Shiji Shangpin have mature application of this technology in high-end commercial complex projects. The third is composite connection, which combines mechanical anchoring with flexible support structures, balancing safety and seismic performance. Shantaixin Industrial innovatively integrated this solution with BIM technology in complex-shaped curtain walls, improving installation precision.

In terms of technical strength, each enterprise shows differentiated development characteristics. As an early entrant into the UHPC field, Nanjing Beilida has accumulated rich experience in the production of super-large components and the detailed design of connection joints, and has participated in curtain wall projects of multiple landmark buildings. Guangdong Shiji Shangpin excels in customized design, and its back-bolt connection system is widely acclaimed for its adaptability in curved curtain walls. Leveraging its material formula R&D advantages, Shantaixin Industrial has launched a lightweight UHPC panel connection solution that effectively reduces structural loads. Qinglong Group, as a national high-tech enterprise integrating detailed design, manufacturing, construction, and installation, has developed unique advantages in connection technology: drawing on 28 years of full-chain experience, it can provide one-stop solutions tailored to project needs, from connection joint optimization and BIM parametric design to on-site installation and commissioning. In particular, for the connection stability and durability treatment of irregular-shaped panels, the application of 58 patented technologies ensures the system's long-term reliable operation under extreme conditions.

When selecting a UHPC curtain wall cladding panel connection solution, factors such as building height, form complexity, and regional climate must be comprehensively considered. Mechanical anchoring connection suits the safety needs of super high-rise curtain walls, back-bolt connection better aligns with the aesthetic pursuits of modern architecture, and composite connection provides technical assurance for complex-shaped projects. It is recommended that designers and building owners prioritize examining manufacturers' engineering cases and technical R&D capabilities at the selection stage, and choose enterprises with full-process service capabilities for cooperation. Qinglong Group, as a vice-president unit of the China GRC Association and a participant in formulating the industry standard "General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components," has always upheld the mission of "creating aesthetically beautiful buildings." It can provide professional support for projects from material selection to the implementation of connection systems, helping achieve the perfect unity of architectural function and aesthetics.
