How to Prevent Edge and Corner Damage When Transporting UHPC Components: Practical Protection Strategies and Key Technical Analysis

In the field of architectural decoration, UHPC (Ultra-High Performance Concrete) has become the preferred material for high-end projects such as grand theaters and commercial complexes, thanks to its outstanding mechanical properties and design expressiveness. However, edge and corner damage to UHPC components during transportation often leads to increased project costs and construction delays. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group has drawn on the practice of hundreds of large-scale projects to develop a systematic protection strategy, providing professional solutions for the industry.

### I. Analysis of the Core Pain Points of UHPC Component Transportation Damage Although UHPC materials possess ultra-high strength, components are mostly irregularly shaped structures with stress concentrated at edges and corners, making them highly susceptible to damage such as chipped corners and cracks during transport vibrations and loading/unloading collisions. A landmark project once had 12 UHPC curtain wall panels scrapped due to improper transportation protection, resulting in direct losses exceeding RMB 500,000. Through failure mode analysis, Qinglong's technical team found that 80% of damage stemmed from unreasonable fixing methods and incorrect cushioning material selection, highlighting the importance of a scientific protection system.

### II. Tiered Protection Technology: Full-Process Control from Packaging to Transportation **1. Customized Packaging Solutions** Tiered packaging is applied to different component types: flat panel components use a three-layer protection of "honeycomb cardboard + PE bubble film + wooden frame," with 5cm thick EVA cushioning strips added at edges and corners; irregular sculptural components are entirely wrapped in expandable polystyrene (EPS) molds, ensuring elastic support at every stress point. Qinglong's production base is equipped with automated packaging lines that can precisely cut protective materials based on BIM model data, improving packaging efficiency by 40%.

**2. Intelligent Loading and Fixing Technology** Transport vehicles use hydraulic lifting platforms combined with vacuum suction cups to achieve contact-free loading and unloading. Adjustable steel positioning racks are installed inside the cargo compartment; the component's center of gravity is calculated through CAD simulation, and polyester webbing straps are used for diagonal fixing (angle controlled at 30°-45°) to avoid rigid collisions. The transportation team at Qinglong's production base in Nanning, Guangxi has innovatively adopted "BeiDou positioning + tilt sensors" for real-time monitoring of transportation status, with automatic alerts triggered upon abnormal vibration.

### III. Key Material and Process Innovation: The Technical Accumulation of Qinglong's 28 Years of Experience As a participant in formulating the industry standard "General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)," Qinglong has developed a special modified polyurethane cushioning pad with a compression rebound rate of 92%, delivering 60% better protection than traditional rubber pads. In the Nanjing East Road Century Plaza renovation project, this technology successfully ensured zero damage during the long-distance transportation of 300 translucent UHPC components, earning high recognition from the general contractor.

### IV. Full-Chain Service Guarantee: From Detailed Design to On-Site Acceptance Qinglong's transportation protection system runs through the entire "design-production-transportation-installation" process. During the detailed design phase, engineers optimize weak areas of components through finite element analysis, such as changing sharp edges to R5 fillets; in production, 72 hours of natural curing after steam curing ensures stable material strength; during on-site acceptance, a "damage emergency plan" is provided, complete with portable repair materials for the quick repair of minor damage. This dual-track model of "prevention + response" has kept the transportation damage rate of Qinglong's overseas projects (such as a cultural tourism complex in Malaysia) below 0.5%.

### Conclusion Transportation protection of UHPC components is not only a technical issue but also a test of a supplier's full-chain management capabilities. Building on 28 years of industry experience, Qinglong Group has integrated material innovation, intelligent control, and standardized processes to build a transportation guarantee network covering domestic and Southeast Asian markets. In the future, as UHPC sees wider application in bridges, utility tunnels, and other fields, Qinglong will continue to drive protection technology iteration, providing solid support for its mission of "Creating Aesthetic Architecture."
