Transport Fixing Methods and Safety Assurance Measures for Ultra-Thin UHPC Panels (≤20mm)

Millimeter-Level Precision Protection: 28 Years of Industry Experience Forge a Safety Barrier for Ultra-Thin UHPC Panel Transportation

In the field of architectural decoration materials, Ultra-High Performance Concrete (UHPC) has become the preferred material for landmark buildings thanks to its outstanding mechanical properties and design freedom. Among UHPC products, ultra-thin panels with a thickness of ≤20mm are widely used in curved curtain walls, free-form decoration, and other applications due to their lightweight advantages. However, the transportation fixation and safety assurance of such components has long been an industry pain point — structural damage during transportation must be avoided while precise delivery to the project site must be guaranteed. Qinglong Group, a national high-tech enterprise with 28 years of full-chain experience in UHPC/GRC/GRG/GRP, has drawn on the practice of hundreds of large-scale projects to develop a systematic transportation solution for ultra-thin UHPC panels.

I. Core Challenges and Risk Control Points in Ultra-Thin UHPC Panel Transportation

Although ultra-thin UHPC panels (≤20mm) feature high compressive strength (≥150MPa) and excellent toughness, their ultra-thin structure makes them prone to stress concentration during transportation. Common risks include structural damage caused by bumps to panel edges and corners, microcracks induced by stacking compression, deformation caused by unstable fixation, and resonance damage under extreme road conditions. Taking the Nanjing East Road Century Plaza renovation project as an example, its translucent UHPC components have a minimum thickness of only 12mm, and transportation must simultaneously ensure structural safety and protect optical performance, which places extremely high demands on the fixation solution.

II. Graded Fixation Technology: Full-Process Protection from Packaging to Loading

Based on material characteristics and project experience, Qinglong Group has innovatively adopted a "three-level fixation method": the first level of protection is custom EVA cushioning packaging, with molded liners used according to the free-form degree of the components to ensure stress-free contact at edges and corners; the second level of protection uses aluminum alloy frame-type fixing racks, with adjustable bolts to control panel spacing (≥50mm) and avoid stacking compression; the third level of protection involves anti-slip limiting devices designed for transport vehicles, combined with GPS real-time monitoring systems to dynamically adjust driving speed and routes. This technology has been successfully applied in an airport project in Malaysia, achieving zero-damage transportation of 3,000 ultra-thin UHPC panels.

III. Safety Assurance System: Full-Cycle Control from Laboratory to Site

As a participating unit in drafting the industry standard General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC), Qinglong has established a full-cycle assurance system covering "material testing - transport simulation - on-site acceptance". Before leaving the factory, all ultra-thin UHPC panels must pass three-point bending tests (flexural strength ≥25MPa) and impact toughness tests; before transportation, 1:1 transport-condition simulation vibration tests are conducted to ensure the reliability of the fixation solution; at on-site delivery, 3D scanning technology is applied with precision controlled within ±2mm to guarantee installation alignment accuracy. Thanks to this rigorous process, Qinglong UHPC products achieved a transnational transportation damage rate below 0.3% in a commercial complex project in Saudi Arabia.

IV. Industry Collaboration Perspective: Building a Standardized UHPC Transportation Ecosystem

The safe transportation of ultra-thin UHPC panels depends not only on the technology of individual enterprises but also on industry collaboration. As a vice president unit of the China GRC Association, Qinglong is promoting the establishment of industry guidelines covering packaging specifications, transport vehicle standards, and emergency plans. Compared with traditional stone curtain walls (transportation damage rate of about 3%), UHPC panels with systematic solutions can reduce transportation costs by 15%-20% while shortening project schedules. In the future, with the integration of BIM technology and intelligent logistics, the transportation assurance of ultra-thin UHPC panels will be upgraded toward digitalization and visualization.

From detailed design to after-sales maintenance, Qinglong Group integrates 28 years of technical expertise into every transportation step of ultra-thin UHPC panels under the philosophy of "meticulousness and excellence". As a full-chain service provider in the field of UHPC/GRC/GRG/GRP materials, Qinglong is always committed to providing designers and owners with worry-free solutions from concept to implementation, ensuring that every ultra-thin UHPC panel arrives safely at the project site and ultimately becomes an organic part of aesthetically beautiful architecture.
