Pallets Protect Freight to be Shipped

If you want your products to be delivered intact, with minimal time to load and unload, appropriately sized pallets will keep freight safe, and reduce the time, labor, and cost of loading and unloading. The optimal pallet size is determined by the size of the product being shipped, and trailer space available.  Standard size pallets have been developed to maximize the amount of freight that can fit in truck trailers.

Standard Pallet Dimensions

GMA Pallets

More than 30% of pallets used in the U.S.  are sized to accommodate consumer packaged goods. These pallets conform to standard pallet sizes developed by the Grocery Manufacturers Association (GMA). Standard GMA sized pallet dimensions are 48″ x 40″, and can hold up to 4,600 lbs. This size pallets are often called GMA pallets.The GMA pallet’s typically weighs 37 lbs., and its height is 6 ½” tall. The deck boards measure 3 ½” wide 5/16” thick each.

Other Common Pallet Dimensions & Sizes

After GMA pallets, the most common pallet dimensions are 42” x 42” and 48” x 48” respectively.

Pallet Types

In addition to the pallet size, you will want to specify the pallet type. Your selection of pallet type and construction is determined by how you will be moving pallets, and the weight the pallet will need to support.

The wood sections on the sides of the pallets are called stringers. The least expensive pallet type is a stringer pallet. The stringer boards have cutout notches, where the forklift tines enter and then lift the pallet. Stringer pallets are either 2-way entry pallets, where the lift can load the pallet from only two of the four sides, or a partial 4-way entry.Partial 4-way pallets can be entered from all four sides with a forklift, but only from two sides with a pallet jack.

For freight that is moved by forklift, pallet jack, or conveyors, and for heavier loads, block pallets are recommended.Block pallets are more flexible when it comes to handling, as they can be lifted from any of the four sides — referred to as full 4-way entry pallets. Conveyor systems may also require block pallets have bottom deck boards that run in both directions.

In summary,

  • Two-way, “unnotched” pallets
    Forklift openings on only two sides, and smaller side openings on remaining sides.
    Stringer boards are on the outside perimeter of the pallet only
  • Stringer pallets
    Forklift openings on only two sides. Middle stringer boards are added in addition to the stringer boards on the perimeter of the pallet for extra support
  • Four-way pallets
    Forklift openings on all four sides, providing the most flexible maneuverability for loading and unloading
  • Block Pallets
    Forklift openings on all four sides, with extra support of solid wood blocks at the end of the stringer boards to support greater loads

The number of deck boards used on the top surface and pallet bottom also add to the strength and durability of the pallet.
