In modern logistics and warehousing, pallets serve as the cornerstone of unitized cargo transportation. Their performance directly impacts the safety and integrity of goods during handling, stacking, and transportation. Despite the increasing emergence of pallets made of plastic and metal, wooden pallets, thanks to their natural material properties and proven manufacturing processes, continue to dominate the global market. In particular, they offer irreplaceable advantages in resisting vibration, preventing slippage, and absorbing shock, making them the preferred carrier for transporting heavy equipment, fragile goods, food, pharmaceuticals, and export goods.1. Natural Elasticity: Excellent Shock Resistance and Cushioning PropertiesWood is a biomaterial with inherent elasticity and toughness. Its fiber structure allows for slight deformation when subjected to stress and then returns to its original shape when the force is removed. This property gives wooden pallets excellent shock absorption and cushioning capabilities. Frequent stops and starts, coupled with jolting and vibration, are unavoidable in road transportation, and cargo is highly susceptible to damage from constant vibration. Wooden pallets effectively absorb and dissipate road impact energy through their elastic structure, reducing the acceleration transferred to cargo, thereby protecting delicate items such as precision instruments, glassware, ceramics, and electronics. In contrast, plastic pallets, while lightweight, are too rigid and offer poor cushioning, while metal pallets are virtually inelastic and easily damaged by impact. The "soft support" properties of wooden pallets are key to their popularity in long-distance transport.2. Rough Surface and Coefficient of Friction: Excellent Anti-Slip PerformanceThe surface of wooden pallets typically retains the natural wood grain or is lightly sanded to create a moderate roughness, imparting high static and kinetic coefficients of friction. This property prevents lateral slippage or displacement when placed on wooden pallets, ensuring stability even when forklifts make sharp turns or vehicles brake. For cartons, bagged materials, or containers with smooth surfaces, wooden pallets provide reliable grip, reducing the risk of cargo toppling or collision. Some wooden pallets also feature anti-slip ridges or a non-slip coating on the top deck to further enhance stability. While wood absorbs moisture and expands in humid environments, its surface friction performance decreases much less than that of smooth plastic or metal pallets, maintaining its basic anti-slip properties.3. Structural Design: Enhanced Overall Impact ResistanceWooden pallets often utilize a longitudinal beam or pad structure, with multiple closely spaced decking boards forming a sturdy grid-like load-bearing surface. This structure not only increases overall load-bearing capacity but also enhances bending and torsional resistance. When subjected to external impact, the force is quickly dissipated throughout the pallet through the crisscrossing beam and board structure, preventing localized stress concentration and damage. For example, during stacking, the contact between upper and lower pallets is surface-to-surface, rather than point-to-point, ensuring even pressure distribution and effectively protecting the underlying cargo. Furthermore, the mortise and tenon or screw joints in wooden pallets offer a certain degree of resilience, making them less susceptible to breakage even under minor impacts, demonstrating excellent durability.4. Breathability Indirectly Enhances StabilityWood is naturally breathable, allowing air to circulate when stacked, helping to regulate the temperature and humidity around the cargo. For fresh fruits and vegetables, dairy products, or goods with high moisture content, this feature prevents condensation accumulation, reduces the risk of packaging slipping and mold, and indirectly improves stability and safety during transportation.5. Cost-Effectiveness and RepairabilityEven in extreme cases, if wooden pallets suffer partial damage, the cost of repair is far lower than replacing the entire pallet. Most damage can be quickly repaired by replacing the panels or reinforcing the crossbeams, allowing the pallets to be put back into service, significantly reducing logistics costs. This "renewable" nature also aligns with the concept of a green, circular economy.With their natural elasticity, high coefficient of friction, sturdy structure, and excellent breathability, wooden pallets offer significant advantages in shock resistance, anti-slip properties, and cushioning. They serve not only as a platform for cargo but also as an invisible "protective barrier," silently ensuring the safe arrival of every item. In the pursuit of efficiency, safety, and sustainability in modern supply chains, wooden pallets, with their unpretentious yet robust and reliable performance, continue to play an indispensable role.
