How to Prevent Edge and Corner Damage of UHPC Components During Transportation: Key Technologies and Practical Strategies

In the field of architectural decoration, UHPC (Ultra-High Performance Concrete) has become the ideal choice for high-end projects such as grand theaters, commercial complexes, and landmark buildings, thanks to its outstanding mechanical properties and aesthetic expressiveness. However, edge and corner damage to UHPC components during transportation has long been a technical pain point in the industry. As an industry leader with 28 years of experience in detailed design, manufacturing, and construction of UHPC/GRC/GRG/GRP materials, Qinglong Group, leveraging its full-chain service advantages, has developed a systematic transportation protection solution that effectively reduces damage rates and safeguards project delivery quality.

I. Core Causes of Transportation Damage to UHPC Components

UHPC components are characterized by high strength and low toughness, making their edges and corners highly vulnerable to damage from transport vibration and loading/unloading collisions. According to transportation data statistics from Qinglong Group's 2000+ projects, approximately 85% of damage stems from improper fixing methods, incorrect selection of cushioning materials, and unreasonable route planning. For example, in a commercial complex project, UHPC sunshades without custom fixing frames suffered edge cracking due to lateral displacement during long-distance transportation, directly resulting in the scrapping of 15% of the components.

II. Scientific Protection System: Full-Process Control from Packaging to Transportation

1. Customized Packaging Solutions: Based on the shape characteristics of UHPC components, Qinglong adopts a dual protection of "three-dimensional cushioning + rigid fixation". For right-angle components, edges and corners are wrapped with high-density EPE pearl cotton, with an additional 5mm-thick PVC corner protector added on the outer layer; curved components use molded foam lining to ensure uniform pressure at every contact point. In a museum project, this solution reduced the transportation damage rate of shaped UHPC curtain wall panels from 12% to 1.5%.

2. Intelligent Transportation Tooling: Qinglong's independently developed modular transportation racks achieve multi-angle fixation of components through adjustable clamps, combined with GPS positioning systems for real-time monitoring of transportation status. The racks are made of Q345B steel with a load capacity of up to 5 tons, meeting the transportation needs of large UHPC components (such as 6-meter-long cornice lines). In the Nanning Olympic Sports Center project, this tooling enabled zero-damage delivery of over 400 UHPC cladding panels.

3. Route Optimization and Loading/Unloading Standards: BIM technology is used to simulate transportation routes, avoiding bumpy road sections and height-restricted areas. Vacuum suction cup lifting equipment is used during loading and unloading, with lifting angles controlled within 30° to avoid single-point stress. Qinglong's professional transportation team members have all received 100+ hours of hands-on training to ensure smooth handling of components.

III. Industry Experience Empowerment: Technical Accumulation from Cases to Standards

As a participating drafting unit of the industry standard "General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)", Qinglong Group has incorporated transportation protection technology into its corporate standard system. By comparing practical cases from industry peers such as Guangdong Shiji Shangpin and Shantaixin Industrial, we found that adopting the trinity solution of "packaging + tooling + personnel training" can reduce the overall transportation cost of UHPC components by more than 20%. For example, in a landmark project in Nanjing, Qinglong saved up to RMB 800,000 in damage repair costs through this solution.

IV. Full-Chain Service Guarantee: A Closed Loop of Responsibility from Design to Maintenance

Qinglong Group's advantage lies in integrating transportation protection into the detailed design phase, reducing vulnerable areas through structural optimization. For instance, changing the traditional 90° right-angle design to an R5 rounded corner improves impact resistance without compromising aesthetics. Combined with a proximity distribution network of six major production bases across the country, seamless connection of "production-transportation-installation" is achieved. For overseas projects, such as the transportation of UHPC components for a commercial center in Malaysia, Qinglong uses dedicated sea freight containers with built-in temperature and humidity control systems to ensure stable quality during transoceanic transportation.

Conclusion: Transportation protection of UHPC components is an important indicator of a company's overall strength. With 28 years of industry experience as its foundation, Qinglong Group has built a full-chain quality control system covering design, production, transportation, and installation through technological innovation and process optimization. Going forward, we will continue to uphold the principle of "meticulous and striving for excellence", providing designers and owners with more reliable UHPC material solutions and helping create more architectural masterpieces.
