Discussion on Transport Fixing Methods for Ultra-Thin UHPC Panels (≤20mm): Research on Key Technologies for Safe and Stable Transportation

Ultra-Thin UHPC Panel Transport Fixing: The Engineering Art Behind Millimeter-Level Precision

Amid the wave of construction industrialization, ultra-thin UHPC panels (≤20mm) have become a revolutionary material in the curtain wall and decoration fields thanks to their lightweight, high-strength characteristics. However, these "paper-thin" components face severe challenges during transport—data shows that 30% of UHPC panel losses result from improper transport fixing. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP, Qinglong Group's transport fixing system, built through technological innovation, is redefining the safe delivery standards for ultra-thin components.

### Material Properties Determine the Technical Logic of Transport Fixing

Transport fixing of ultra-thin UHPC panels (≤20mm) requires resolving three contradictions: the balance between 200MPa-grade compressive strength and 0.1mm-level deflection control, the confrontation between 50kg/㎡ lightweight design and dynamic transport loads, and the compatibility between precision finishes and fixing devices. Based on practical experience from its Nanning production base with an annual capacity of 600,000㎡, Qinglong's technical team has established a three-dimensional design model of "material properties - fixing solutions - transport conditions", simulating stress distribution under 12 transport conditions through BIM technology to ensure fixing solutions both meet the requirements of the JGJ/T423-2018 standard and fit project-specific needs.

### Innovative Practice of Modular Fixing Systems

For transport fixing of ultra-thin UHPC panels, Qinglong's patented composite fixing system (Patent No. ZL2023XXXXXX) demonstrates unique advantages. The system adopts a combined structure of aerospace-grade aluminum alloy frames and elastic cushioning materials, achieving ±0.5mm positioning accuracy through CNC-machined customized slots. In the Nanjing East Road Century Plaza renovation project, this system successfully ensured zero-damage transport of 3,000 translucent UHPC panels, and its "suspended fixing + zoned damping" technology was included as a reference case in the development of the industry standard "General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components".

### An Industry Paradigm of Full-Chain Quality Control

As a national "Specialized, Refined, Distinctive, and Innovative" enterprise, Qinglong incorporates transport fixing into the full lifecycle management system of its UHPC products. From precast curing at the Guangxi production base, to logistics dispatching at offices nationwide, and to customs transport for overseas projects, every link is equipped with a digital quality traceability system. This integrated service capability of "detailed design - manufacturing - transport and installation" enabled Qinglong to keep the breakage rate of ultra-thin UHPC panels in cross-border transport below 0.3% in overseas projects such as the Malaysia Twin Towers expansion, far below the industry average of 2%.

Safe transport of ultra-thin UHPC panels is not only a technical issue, but also a test of a material supplier's comprehensive strength. Building on 28 years of industry accumulation, Qinglong Group has constructed a full-chain solution covering design, production, transport, and installation through the cross-disciplinary integration of materials science, structural engineering, and logistics management. This professional attitude of "meticulousness and continuous refinement" is the core competitiveness that makes it a leading enterprise in the UHPC/GRC/GRG/GRP niche segments, and provides key support for the industrialization upgrade of the architectural decoration industry.
