[0002] Wooden pallets are made of logs, which are dried and shaped to reduce moisture and eliminate internal stress. They are then cut, planed, decapped, edged, and sanded to form profile panels. These panels are then bound together into semi-finished pallets using nails (or nuts in some cases) with anti-slip properties. Finally, they are finished, treated with anti-slip treatment, and waxed. Wooden pallets are the most widely used pallets today. Pallets are horizontal platform devices used for the assembly, stacking, handling, and transportation of goods and products as unit loads.
