Ultra-Thin UHPC Panel (≤20mm) Transport Fixing Solution: Qinglong's Safety Assurance Practice

Ultra-thin UHPC panels (≤20mm), due to their thin thickness and low stiffness, are prone to bending and breakage during transportation. A scientific transportation fixing method is key to ensuring product quality. Drawing on extensive experience in transporting ultra-thin components, Qinglong Group has developed a safe and reliable fixing solution.

I. Core Transportation Risks of Ultra-thin UHPC Panels The transportation risks of ultra-thin UHPC panels mainly stem from three aspects: first, insufficient inherent stiffness, as bumps during long-distance transportation can easily cause bending deformation; second, fragile surfaces, where collisions or friction can easily cause scratches and edge chipping; third, stacking pressure, as bottom panels in multi-layer stacks are prone to compression damage. Qinglong's tests found that without dedicated fixing methods, the transportation breakage rate of 20mm-thick UHPC panels can exceed 15%, while with standardized fixing, the breakage rate can be reduced to below 1%.

II. Core Fixing Methods: Customized Protection and Precise Positioning Qinglong adopts a triple fixing solution of "custom brackets + cushioning protection + layered fixing". The custom brackets are made of high-strength aluminum alloy, with slot-type structures designed according to the dimensions of the ultra-thin panels, and 5mm-thick rubber buffer pads pasted inside the slots to restrict horizontal and vertical displacement of the panels. For cushioning protection, the panel surfaces are covered with PE protective film, and hard plastic corner protectors are added to the edges to prevent collision damage. Layered fixing adopts a spaced layout, with 30mm-thick honeycomb cardboard placed between each layer of panels, and compression devices installed at the top of the brackets to ensure no relative sliding during transportation. In the Shanghai Astronomy Museum public art project, Qinglong used this solution to transport 20mm-thick ultra-thin UHPC sculpture components with zero breakage throughout the journey.

III. Transportation Process and Detail Control: Full-Chain Safety Assurance Beyond fixing methods, detail control of the transportation process is equally important. Qinglong's transportation process includes: panel strength testing before shipment (panels can only be transported if bending strength is ≥15MPa), dedicated vehicles (flatbed trucks are used to avoid squeezing inside containers), transportation route planning (avoiding bumpy road sections, with speed controlled within 60km/h), and on-site unloading (vacuum suction cup lifting devices are used to avoid direct dragging). In the Ouargla Hotel project in Algeria, Qinglong transported 20mm-thick ultra-thin UHPC perforated panels from China to overseas, achieving zero-breakage delivery of thousands of panels through this full-chain control. In addition, Qinglong purchases transportation insurance for each batch of ultra-thin panels to further reduce risks.

The transportation fixing of ultra-thin UHPC panels (≤20mm) relies on customized solutions and refined control to prevent transportation issues from affecting project progress and quality. With its extensive experience in transporting ultra-thin components, Qinglong Group has established a mature safety assurance system. Choosing a supplier with specialized transportation capabilities is the core guarantee for the safe delivery of ultra-thin UHPC panels.
