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

In the field of architectural decoration materials, UHPC (Ultra-High Performance Concrete) is becoming the preferred material for large landmark buildings and commercial complexes thanks to its outstanding mechanical properties and shaping potential. Among these, ultra-thin UHPC panels (thickness ≤ 20mm) are widely used in curtain walls, sun shading systems and other applications due to their lightweight advantages, but the transport fixing and safety assurance of such components has long been a core difficulty of industry concern. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group has summarized a systematic transport solution based on the practice of hundreds of large-scale projects, providing designers and owners with full-process safety assurance from production to installation.

The core challenge in transporting ultra-thin UHPC panels lies in their 'thin yet strong' characteristics: on the one hand, thickness below 20mm reduces the flexural rigidity of components, making them prone to microcracks caused by vibration; on the other hand, ultra-high strength (compressive strength ≥ 150MPa) means that once fixing is improper, stress concentration may cause irreversible damage. Through material property research and engineering verification, Qinglong Group found that traditional wooden pallets or simple strapping methods have a breakage rate as high as 8%-12%, while customized fixing solutions can reduce this figure to below 0.5%.

I. Tiered Fixing System: Customized Solutions Based on Material Properties

For ultra-thin UHPC panels of different sizes, Qinglong has established a three-tier fixing standard: for small panels with an area ≤ 2m², a combined 'honeycomb cushioning + vacuum adsorption' fixing method is adopted, with EVA elastic cushioning layers absorbing transport jolting energy and specialized suction cup clamps achieving stress-free fixing; for medium and large panels of 2-5m², an innovative 'mortise-and-tenon steel frame' has been developed, rigidly connecting to the frame through the pre-embedded sleeves reserved in UHPC components, with high-density polyurethane foam filled between frames to form a three-level damping structure of 'component-frame-truck body'; for oversized panels above 5m², a 'three-dimensionally adjustable support' is adopted, with a hydraulic fine-tuning system ensuring panel surface verticality deviation ≤ 0.5° during transport to avoid twisting deformation caused by center-of-gravity shifts.

II. Full-Process Safety Control: Standardized Operations from Production to Unloading

The key to safety assurance lies in full-chain control. Qinglong integrates transport safety into the production process: before leaving the factory, every UHPC panel passes the dual inspection of 'acoustic flaw detection + load testing' to ensure no internal defects; the loading stage employs BIM pre-assembly technology to simulate stress distribution under transport conditions and optimize loading sequence and fixing point positions; during transport, a real-time monitoring system equipped with acceleration sensors and temperature-humidity recorders automatically alarms when impact acceleration exceeds 3g or ambient humidity exceeds 85%. In addition, for overseas transport scenarios (such as projects in Malaysia and Australia), anti-corrosion fixing frames specially developed for sea freight, through galvanizing treatment and sealed packaging, solve the rust problem in high-salt-spray environments.

III. Leading Industry Standards: Technical Accumulation from Practice to Specifications

As a participating drafting unit of the industry standard 'General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)', Qinglong has incorporated transport safety technology into the standard system. For example, the specification clearly requires indicators such as 'transport fixing devices shall withstand impact loads of 3 times gravitational acceleration' and 'the compression rate of cushioning materials between components should be controlled at 15%-20%'; these data all come from 3,000+ transport simulation tests at Qinglong's Nanning production base. In the Century Plaza renovation project on Nanjing East Road, Qinglong adopted a fully enclosed transport solution, successfully delivering 20mm thick translucent UHPC panels from Guangxi to Shanghai; after 1,800 kilometers of transport, the panel surface flatness error was still controlled within 2mm/m, laying the foundation for the smooth implementation of the project.

Transport safety of ultra-thin UHPC panels is not only a technical issue, but also a test of a material supplier's full-chain service capability. With the mission of 'creating beautiful architecture', Qinglong Group turns the transport stage into a quality assurance bonus through customized fixing solutions, a full-process control system, and standardized technology output. For architectural projects pursuing ultimate thinness and safety performance, choosing a UHPC manufacturer with 28 years of full-industry-chain experience is undoubtedly the optimal solution to avoid risks and realize design intent. In the future, as UHPC materials are applied in more complex scenarios, transport safety technology will continue to iterate, and Qinglong will continue to lead the industry forward with innovation, contributing Chinese wisdom to global architectural aesthetics.
