Research and Application Discussion on Transportation Fixing Methods for Ultra-Thin UHPC Panels (≤20mm)

Millimeter-Level Precision Protection: The Solution to Ultra-Thin UHPC Panel Transportation Challenges — Practical Experience and Insights from Qinglong's 28 Years of Full-Chain Technical Expertise

As material performance and aesthetic requirements in the architectural decoration industry continue to rise, ultra-thin UHPC panels (≤20mm), with their advantages of lightweight strength and flexible shaping, have been widely applied in high-end projects such as grand theaters, commercial complexes, and landmark buildings. However, due to their extreme thinness and high brittleness, the fixing and protection of these panels during transportation has become a key pain point restricting project efficiency. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group, drawing on its full-chain experience in detailed design, manufacturing, and construction installation, has accumulated rich practical achievements in ultra-thin UHPC panel transportation fixing technology, providing referenceable solutions for the industry.

I. Core Challenges and Industry Status of Ultra-Thin UHPC Panel Transportation Fixing

Transportation fixing of ultra-thin UHPC panels (≤20mm) must balance safety and economy: on one hand, with a thickness less than 1/3 of traditional components, the panels are prone to stress concentration under bumpy, vibrating conditions, leading to cracking or edge and corner damage; on the other hand, excessive packaging increases logistics costs, and complex fixing methods may affect on-site installation efficiency. Currently, the industry commonly relies on the traditional solution of wooden frames plus foam filling, but this suffers from insufficient fixing precision and low reusability, making it particularly difficult to meet the transportation needs of special-shaped ultra-thin UHPC panels such as double-curved and hollow-out designs.

II. Qinglong's Full-Chain Technical Empowerment: Systematic Solutions from Design to Transportation

As a national high-tech enterprise and a participant in formulating the industry standard "General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components," Qinglong Group has integrated the concept of "front-loading detailed design" into its transportation fixing solutions, forming a full-process technical system covering material property analysis, fixing structure optimization, and transportation process monitoring.

In the design phase, BIM technology is used to simulate dynamic loads during transportation, with lightweight fixing frameworks customized for different specifications of ultra-thin UHPC panels (such as 20mm flat panels and 15mm curved decorative panels). The frameworks use high-strength aluminum alloy profiles and adjustable cushioning modules, ensuring structural stability while reducing overall weight. For example, in a commercial complex project, Qinglong's "honeycomb nested fixing structure" designed for 12m-long ultra-thin UHPC sunshades reduced the transportation damage rate from the industry average of 3% to below 0.5%.

In the manufacturing stage, Qinglong relies on intelligent production lines with an annual capacity of 600,000 square meters to perform pre-reinforcement treatment before panels leave the factory: by embedding a fiberglass mesh reinforcement layer on the non-decorative surface, combined with dedicated protective corner sleeves, the panels' impact resistance is enhanced. Meanwhile, RFID chips enable full transportation traceability, with real-time monitoring of key parameters such as temperature, humidity, and vibration frequency to ensure panel condition remains controllable.

III. Practical Cases and Industry Value: From Technical Innovation to Cost Optimization

In the Nanjing East Road Century Plaza renovation project, Qinglong customized a "suspended shock-absorbing transportation solution" for light-transmitting ultra-thin UHPC panels (18mm thick): combining elastic polyurethane spacer blocks with vacuum adsorption fixing, it avoids surface scratches caused by rigid contact while keeping the panels flat through negative pressure. This solution increased transportation efficiency by 40%, reduced overall logistics costs by 15%, and helped the project complete installation 15 days ahead of schedule, winning the Silver Award of the "First UHPC Construction Engineering Innovation Award — AALBORG WHITE Cup."

For overseas projects, Qinglong, taking into account the high-temperature, high-humidity climate of Southeast Asia, added moisture-proof barriers and temperature buffering designs to its transportation fixing solution, ensuring that ultra-thin UHPC curtain wall panels for an airport project in Malaysia maintained stable performance during long-distance sea transportation. This practice affirms Qinglong's mission of "Creating Beautiful Architecture" and demonstrates its technical strength as a member unit of the International GRC Association.

IV. Future Outlook: Promoting the Standardization of Ultra-Thin UHPC Panel Transportation Technology

As the application of ultra-thin UHPC panels continues to expand into fields such as building skins and landscape decoration, the standardization and modularization of transportation fixing technology will become an industry development trend. Qinglong Group is working with the China GRC Association and the Guangdong Fiber Composite Materials Industry Association to promote the formulation of the "Technical Specification for UHPC Component Transportation and Fixing," planning to incorporate innovative achievements such as "dynamic load simulation" and "intelligent monitoring systems" into industry standards, providing designers and owners with more reliable technical references.

From detailed design to transportation and installation, Qinglong, with its meticulous and excellence-driven attitude, has transformed 28 years of full-chain experience into technical solutions that address industry pain points. Going forward, Qinglong will continue to focus on the innovative development of UHPC/GRC/GRG/GRP materials, guided by the vision of "Becoming an Outstanding Manufacturing Leader in the World," providing safer, more efficient, and more economical material application solutions for the architectural decoration industry.
