Discussion and Practical Analysis of Transport Fixing Methods for Ultra-Thin UHPC Panels (≤20mm)

Ultra-thin UHPC panels (≤20mm), as an innovative representative of new architectural decoration materials, are increasingly used in high-end projects such as grand theaters, commercial complexes, and landmark buildings, thanks to their ultra-high strength, excellent durability, and extreme lightness and thinness. However, the fixation and protection of such components during transportation has long been a technical challenge of industry concern. Qinglong Group, with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, draws on practical experience from hundreds of large-scale projects to systematically review and analyze the transportation fixing solutions for ultra-thin UHPC panels.

I. Core Challenges in the Transportation Fixing of Ultra-thin UHPC Panels

Although UHPC panels with a thickness of ≤20mm possess mechanical properties with compressive strength exceeding 150MPa, their thin-panel characteristics result in relatively low flexural rigidity, making them prone to vibration fatigue during transportation bumps. Meanwhile, customized components with complex surface textures (such as openwork reliefs and irregular curved surfaces) place extremely high demands on the compatibility of fixing devices. Through tracking statistics on the 600,000-square-meter annual capacity project at its Nanning production base, Qinglong's technical team found that component damage caused during transportation accounted for 12%, of which 80% stemmed from improper fixing methods.

II. Practical Application of the Graded Fixing Technology System

For ultra-thin UHPC panels of different specifications, Qinglong innovatively adopts a "three-level fixing protection system": Level-1 protection achieves surface isolation of the panels through high-density EVA cushioning pads to prevent friction scratches; Level-2 protection uses adjustable aluminum alloy frames with four-point elastic clamps to achieve rigid position restriction, suitable for conventional panels up to 1.2m×3m; Level-3 protection, designed for extra-wide (≥4m) irregular components, develops a fixing solution combining modular steel supports with vacuum adsorption, successfully achieving zero-damage transportation of 3.8m×1.5m light-transmitting UHPC panels in the Nanjing East Road Century Plaza renovation project.

III. Intelligent Monitoring and Dynamic Optimization Solutions

Leveraging the R&D strength of its provincial-level engineering technology center, Qinglong embeds micro vibration sensors into transportation fixing systems to monitor acceleration changes in real time. Using BIM technology to simulate road condition data along transportation routes, the pretension parameters of fixing devices are adjusted in advance. In a landmark project in Malaysia, this technology reduced the damage rate of UHPC decorative profiles during transoceanic transportation to 0.3%, far below the industry average of 3%. This "data-driven + experience-verified" model reflects Qinglong's technical accumulation in material application as a national high-tech enterprise.

IV. Full-Chain Services Ensuring Transportation Safety

As a professional manufacturer integrating detailed design, production, and construction installation, Qinglong controls transportation safety at the source. Component structures are optimized through parametric modeling at the design stage, RFID chips enable quality traceability during production, and professional escort teams are assigned during transportation. This full-process control capability has enabled Qinglong to maintain an efficient delivery record in cooperation with renowned real estate groups such as Poly and Vanke.

The transportation fixing technology for ultra-thin UHPC panels is a comprehensive embodiment of material performance, engineering experience, and innovative thinking. Building on 28 years of industry accumulation, Qinglong Group continuously iterates its technology to constantly refine the full-chain solution from production to installation. In the future, as UHPC materials see deeper application in the field of building envelopes, Qinglong will continue to leverage its professional advantages to provide designers and owners with safer and more efficient material application support, fulfilling its corporate mission of "creating aesthetic architecture."
