Wooden pallets are made from logs, which undergo drying and shaping to reduce moisture and eliminate internal stress. They are then cut, planed, trimmed, edged, and sanded to form profile panels. These panels are then assembled into semi-finished pallets using anti-loosening nails (and in some cases, nuts). Finally, they undergo finishing, anti-slip treatment, and waxing. Wooden pallets are currently the most widely used type of pallet. Pallets are horizontal platform devices used for assembling, stacking, handling, and transporting goods and products as unit loads. They are generally made of wood, metal, or fiberboard, facilitating the loading, unloading, and handling of unitized materials and small quantities of goods.
Log Materials: Currently, the main materials used for wooden pallets in China are pine, hemlock, fir, and other miscellaneous hardwoods. Different materials represent different performance characteristics of the pallets. European pallet standards explicitly prohibit the use of poplar.
Moisture Content: The moisture content of the logs used for pallets affects the shrinkage, deformation, and even cracking of the pallet. High-standard pallets have strict controls on their moisture content. European standards for wooden pallets stipulate that the moisture content must not exceed 22% of the wood's weight when dry. A moisture content between 22% and 26% is defined as a minor defect, while a content exceeding 26% is considered unacceptable.
