Pallet Rack Systems: Block Pallets and Stringer Pallets
Just like pallet rack, pallets come in many styles, sizes, materials, and configurations. However, all pallets fall into one of two categories: Stringer pallets and Block pallets. When Block or Stringer pallets are manufactured, they are usually suited to a specific load, moving system, and pallet rack system. Here is a brief explanation of Stringer pallets and Block pallets:
Stringer pallets: are the most common pallet used in the United States. On a Stringer pallet, there are three long parallel boards sandwiched in between the top and bottom deckboards. These parallel boards are called “stringers,” which support the load on the pallet. The top and bottom of the Stringer pallet has flat deckboards which are attached to the stringers in between them. Stringer pallets may be “two-way pallets” (because a pallet jack or forklift can only lift them from two directions)—or if the stringers are notched to allow access from all four sides, the Stringer pallet can be a “four-way pallet.”
Block pallets: cost more to manufacture than Stringer pallets, but Block pallets are typically stronger. In a block pallet, the top deckboards are supported by 4 to 12 blocks of wood. A Block pallet may or may not have bottom deckboards. The major advantage of a Block pallet is that it can be accessed from all four sides with a pallet jack or forklift, making it a true four-way pallet. Since the Block pallet is internally supported by blocks, and not boards, there is more open space for a pallet jack or forklift to lift the pallet.
