Block and stringer pallets are the two most common types of pallets. Each has a different use case.
The stringer pallet is the most common type of pallet used in the United States. Pallets with stringers are called stringers because they use “stringers” to support the unit load. Stringers are the board that are sandwiched between the top and bottom deckboards, and are typically made out of 2 x 4’s or 3 x 4’s.
Stringer pallets tend to be cheaper due to the wide scale manufacturing of them. They are also the most commonly recycled pallet. Used stringers are often classified as grade A or grade B depending on condition.
Stringer Pallet Uses:
Grocery stores
Warehousing
Lighter loads
One way shipping
Block pallets use blocks of solid wood, plywood, or plastic to support the unit load. To support the top deck boards, block pallets typically use four to twelve blocks. There are thin stringers, which form a mat with the deck boards, between the blocks and the deck boards. A block pallet’s length is determined by the stringer board’s length and its width by the duckboard’s length, just as a stringer pallet. There are different types of block pallets, including those with and without bottom deck boards, and those with full perimeter bases.
Block Pallet Uses:
Heavy duty loads
