How to Prevent Edge and Corner Damage During UHPC Component Transportation: Key Technologies and Practical Measures

The slightest difference in transportation determines the perfect presentation of UHPC components — a full-chain protection solution distilled from 28 years of industry experience

Driven by the dual forces of contemporary architectural aesthetics and engineering technology, Ultra-High Performance Concrete (UHPC) has become the preferred material for high-end projects such as landmark buildings and commercial complexes, thanks to its outstanding mechanical properties and molding plasticity. However, during transportation from the production base to the construction site, edge and corner damage to UHPC components—caused by the brittle nature of the material and complex shape requirements—has always been an industry pain point. As a full-chain solution provider with 28 years of deep expertise in the UHPC/GRC/GRG/GRP materials field, Qinglong Group has drawn on practical experience from thousands of projects to develop a systematic transportation protection technology system, ensuring that every customized component arrives safely at the installation site.

I. Analysis of the Core Causes of UHPC Component Damage During Transportation

The ultra-high strength of UHPC material itself (compressive strength can exceed 150MPa) and its low ductility make it highly prone to stress concentration when subjected to impact or uneven loading. In transportation scenarios, common damage risks include: collisions between components caused by vehicle bumps, accidental scratches during hoisting, structural deformation caused by unstable fixing, and thermal stress damage under extreme weather conditions. In a commercial complex project, the lack of targeted protective measures resulted in 20% of the UHPC decorative lines suffering edge chipping during transportation, causing not only direct economic losses but also delays to critical construction milestones.

II. Full-Process Protection Technology: Standardized Operations from Packaging to Unloading

Through full-chain coordination of detailed design, production and manufacturing, and construction installation, Qinglong Group has established a "three-tier protection system":

1. Customized Packaging Solutions: A composite protection approach of "soft wrapping + hard support" is adopted for components of different shapes. Flat components are fully covered with EPE pearl cotton, with 5mm thick high-density polyethylene corner protectors added at the corners; irregular curved components use dedicated foam molds generated through 3D scanning to achieve precise point-to-point fixing. At the Nanning production base, every UHPC component is equipped with a recyclable steel frame transportation rack, which forms flexible contact with the component surface through rubber buffer pads.

2. Intelligent Loading and Fixing Technology: BIM technology is used to simulate transportation conditions and calculate the optimal loading and ballast plan. Transport vehicles are equipped with hydraulic shock absorption systems; components are rigidly fixed to each other with adjustable steel clamps, and combined with pre-tightening force monitoring devices, displacement during transportation is kept within 2mm. In a museum project, this technology enabled the deformation-free transportation of an 8-meter-long UHPC decorative cornice.

3. Full-Journey Monitoring and Emergency Response: Transport vehicles are fitted with temperature and humidity sensors and three-axis acceleration recorders to monitor environmental changes and impact intensity in real time. When monitoring data exceeds the threshold, the system automatically triggers an alert, and the dispatch center can immediately adjust the driving route or stop for inspection. Qinglong's overseas project team once used this system to promptly detect abnormal vibration during transportation in Malaysia, avoiding damage to GRP daylighting roof components worth one million yuan.

III. Industry Experience Empowerment: Practical Verification of 28 Years of Technical Accumulation

As an enterprise that participated in formulating the industry standard "General Technical Requirements for Non-Load-Bearing Ultra-High Performance Concrete (UHPC) Components", Qinglong Group has incorporated transportation protection technology into its product life-cycle management system. By integrating structural optimization at the detailed design stage (such as chamfering and stiffener design), curing control during production (28-day standard curing to ensure strength stability), and precise alignment during construction and installation, a closed-loop solution is formed. In the renovation project of Century Plaza on Nanjing East Road, this system achieved zero-damage transportation of light-transmitting UHPC components, with installation precision errors controlled within 1mm, winning the AALBORG WHITE Cup UHPC Construction Engineering Innovation Award.

From understanding material properties to putting engineering into practice, transportation protection of UHPC components is not only a technical issue but also a systems engineering endeavor. With the mission of "creating beautiful architecture", Qinglong Group transforms its 28 years of industry experience into standardized solutions, providing designers and owners with full-chain assurance from detailed design to after-sales maintenance. In the field of new architectural decorative materials, only by carrying detail control through every link can the mechanical beauty and artistic beauty of UHPC be perfectly integrated into the city skyline.
