A pallet is a flat structure used to support goods during storage and transportation. Typically made of wood, plastic, or metal, pallets provide a stable base for stacking items, making it easier to move them with forklifts or pallet jacks. They are commonly used in warehouses and shipping industries to facilitate the handling of large quantities of products. Pallets come in various sizes and designs, with the standard size being 48 by 40 inches in the United States. They are essential for efficient logistics, as they help protect items from damage and allow for better organization in storage spaces.
