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

[Transport Fixing of Ultra-Thin UHPC Panels: Solving the Engineering Challenge of Extreme 20mm Thickness]

Amid the wave of innovation in building materials, Ultra-High Performance Concrete (UHPC) has become a new favorite of high-end architecture for its ultra-high strength and durability. When thickness is compressed to below 20mm, this "wafer-thin" ultra-thin UHPC panel faces unprecedented challenges in transport. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group leverages its full-chain technical strength to provide systematic solutions for the safe transport of ultra-thin UHPC panels.

### Analysis of the Core Pain Points in Ultra-Thin UHPC Panel Transport

Although UHPC panels with thickness ≤20mm offer outstanding performance with compressive strength exceeding 150MPa, their ultra-thin nature leads to reduced rigidity and susceptibility to deflection deformation. In traditional transport modes, the common stacked fixing method easily causes panel surface scratches and chipped edges and corners, and in extreme cases can even trigger interlayer delamination. Data from a landmark project shows that the transport loss rate of ultra-thin UHPC panels without professional fixing can reach 8-12%, far exceeding the industry average standard of 5%.

### Technical Breakthroughs of Qinglong's Innovative Fixing System

Based on the technical accumulation of a national-level R&D center, the Qinglong team has developed a "3D Flexible Fixing System": a combination of aviation-grade aluminum alloy frames and high-density EVA cushioning layers, with CNC precision-machined positioning clamps achieving uniform six-point loading on the panel. In simulated transport tests at the Nanning production base, this system successfully kept the transport loss of 20mm-thick UHPC panels sized 3m×1.2m below 0.3%, and the related technologies have obtained 3 utility model patents.

### Practical Path of Full-Chain Transport Assurance

As a national-level high-tech enterprise integrating detailed design, manufacturing, and construction installation, Qinglong has established a full-process control system from factory to construction site. In a commercial complex project in Guangdong, by rehearsing transport routes with BIM technology, combined with customized vacuum suction lifting devices and constant temperature and humidity transport carriages, Qinglong achieved zero-damage delivery of 1,200 ultra-thin UHPC curtain wall panels. This integrated "design-manufacturing-transport" service model is precisely Qinglong's core competitiveness as a professional UHPC manufacturer.

### Leading Industry Standards and Future Outlook

Qinglong Group, which participated in formulating the industry standard "General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)", is promoting the inclusion of transport fixing technology into the standardization system. As UHPC materials find wide application in high-end buildings such as grand theaters and museums, Qinglong will continue to optimize its "flexible fixing + intelligent monitoring" transport solutions, providing a replicable technical paradigm for the industry. As advocated by Qinglong's mission of "Creating Beautiful Architecture", every ultra-thin UHPC panel delivered safely is a perfect fusion of technology and art.

From laboratory data to engineering practice, Qinglong's 28 years of industry experience prove that transport fixing of ultra-thin UHPC panels is not merely a technical issue, but also a matter of deep understanding of material properties, engineering logic, and safety responsibility. This is exactly what gives Qinglong the confidence to lead the niche market of UHPC/GRC/GRG/GRP architectural decorative materials.
