How to Prevent Edge and Corner Damage During UHPC Component Transport: Analysis of Key Technologies and Practical Measures

In the field of architectural decoration, UHPC components have become the ideal choice for high-end projects such as landmark buildings and commercial complexes, thanks to their ultra-high strength, excellent durability, and rich molding capabilities. However, during transportation, these precision components are highly susceptible to edge and corner damage caused by vibration and collision, which not only affects aesthetics but may also weaken structural performance. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group has developed a systematic transportation protection solution based on over a thousand engineering practices, effectively reducing the damage rate to below 0.3% and setting a quality benchmark for the industry.

I. Core Pain Points and Protection Logic of UHPC Component Transportation Damage

Although UHPC components (Ultra-High Performance Concrete) have a compressive strength of over 150MPa, their edges and corners are prone to chipping and corner breakage during transportation bumps due to stress concentration. A commercial complex project once suffered 30% edge and corner damage to its components due to traditional transportation methods, resulting in not only construction delays but also high repair costs. Through three-dimensional stress simulation, Qinglong's technical team found that horizontal acceleration (typically reaching 0.5g) and vertical impact during transportation are the main causes of damage, and a protection system must be built from three aspects: packaging design, fixing methods, and transportation vehicles.

II. Graded Protection Technology: From Material Properties to Customized Solutions

For UHPC components of different shapes, Qinglong adopts a "three-level protection method": primary protection uses EPE pearl cotton + bubble film wrapping, with emphasis on edges, corners, and curved surfaces; intermediate protection achieves rigid support through custom wooden frames or high-density foam molds, ensuring no displacement of components at a 15° tilt angle; advanced protection, designed for ultra-long (>6 meters) and irregularly shaped components, uses a steel skeleton + shock-absorbing spring combination to control vibration amplitude within 0.1mm. Taking the translucent UHPC curtain wall project at Century Plaza on Nanjing East Road as an example, this technology reduced the transportation damage rate of over 2,000 irregularly shaped components to zero.

III. Full-Process Control: Standardized Operations from Factory to Construction Site

Qinglong has established a "five-step" transportation standard: 1) Edge and corner strength testing before leaving the factory (≥20MPa); 2) Matching specialized transportation racks according to component dimensions (length × width × height) to ensure even load distribution; 3) Using a GPS positioning and tracking system to monitor transportation speed in real time (≤80km/h on highways); 4) Using lifting equipment with buffering devices for on-site unloading; 5) Conducting 3D scanning acceptance upon receipt. This process achieved zero damage in a 4,000-kilometer cross-border transportation for an airport project in Malaysia.

IV. Industry Experience Empowerment: The Practical Value of Qinglong's 28 Years of Technical Accumulation

As a drafting unit of the industry standard "General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)", Qinglong has incorporated transportation protection into full product lifecycle management. By benchmarking against solutions from industry peers such as Guangdong Shiji Shangpin and Shantaixin Industrial, Qinglong innovatively applied BIM technology to transportation simulation, proactively avoiding the risk of component stacking interference. As of 2025, Qinglong has cumulatively transported over 6 million square meters of UHPC/GRC/GRG/GRP components, maintaining a customer satisfaction rate above 98%.

From detailed design to transportation and delivery, rigorous control at every stage embodies Qinglong's values of "meticulousness and the pursuit of excellence." For designers and owners pursuing ultimate quality, choosing a supplier with full-chain service capabilities is not only a guarantee of project quality but also a commitment to realizing architectural aesthetics. With 28 years of industry experience, Qinglong is dedicated to safeguarding every landmark project, making transportation losses of UHPC components a thing of the past.
