Composite pallets combine materials like wood, plastic, and metal to capitalize on the strengths of each. These pallets are engineered to meet specific requirements, offering a balance between durability, weight, and cost.
Stringer pallets utilize a frame of three or more parallel pieces of timber (stringers) that support the load. They are often referred to as "two-way" pallets because a forklift can lift them from only two sides. Variations include notched stringer pallets, allowing partial four-way entry, enhancing flexibility in handling.
Block pallets are constructed with blocks of solid wood or plastic supporting the top deck, allowing for true four-way entry by forklifts and pallet jacks. This design enhances efficiency in handling and is commonly used in international shipping due to its robustness and ease of access. Block pallets are integral to the operations of large retailers and warehouse clubs.
Double-face pallets have decks on both the top and bottom, providing additional strength and stability. Double-wing pallets feature deck boards extending beyond the stringers or blocks on both sides, increasing the load surface area. These designs are suitable for handling bulky or irregularly shaped loads, distributing weight more evenly.
Standardizing pallet sizes is critical for optimizing space in transportation and storage, ensuring compatibility with equipment and infrastructure. ISO standards have established six pallet sizes recognized internationally. The most common sizes include:
