Types of Pallets Explained: Stringer vs Block, Materials, and Which to Choose

"Pallet" is one word for a lot of very different structures. Pick the wrong type and you get forklift entry problems, weak loads, failed exports or wasted money. This is the full breakdown of pallet types and how to choose.

The two structural types: stringer vs block

The biggest distinction is how the pallet is built underneath:

• Stringer pallets use parallel boards ("stringers") between the top and bottom decks. A basic stringer pallet allows 2-way forklift entry (notched stringers can allow partial 4-way). Cheaper, common.
• Block pallets use solid blocks at the corners and midpoints, giving full 4-way entry — a forklift or pallet jack can enter from any side. Stronger and easier to handle; the basis of many standard and export pallets.

Pallet vs skid: a pallet has a top and a bottom deck; a skid has only a top deck (no bottom boards). Skids are simpler but less stable for stacking.

Entry types

• 2-way entry: forklift enters from two opposite sides only.
• 4-way entry: access from all four sides — faster handling, fewer repositioning moves on a busy dock.

For high-throughput dispatch, 4-way block pallets reduce handling time.

Pallet materials

Reversible vs non-reversible, wing vs flush

• Reversible pallets have identical top and bottom decks — usable either way up.
• Non-reversible have a distinct top deck (often for delicate loads).
• Wing pallets have top/bottom decks overhanging the stringers (for strapping or bar handling); flush pallets do not.

How to choose the right pallet

1. Handling: need 4-way access on a busy dock? Choose a block pallet.
2. Load weight: match the pallet's rated capacity to your heaviest load.
3. Export: wood needs ISPM-15; plastic avoids it entirely.
4. Reuse / hygiene: plastic for many trips, washdown, pharma and food.
5. Your machine's range: make sure your strapping/handling equipment fits the pallet's height and width.

Don't forget what holds the load on the pallet

Choosing the right pallet is half the job — the load still has to be secured to it. Whatever pallet type you run, the load should be strapped to the deck at consistent tension so it travels as one unit. Mobile machines such as the ErgoPack 726X, GO and 700 handle the full range of pallet widths (40–270 cm) on the same floor. See how to pack a pallet for shipping.

Pallet type quick reference

• Stringer = cheaper, usually 2-way; block = stronger, 4-way
• Pallet has two decks; a skid has one
• Match material to route: ISPM-15 wood or plastic for export
• 4-way block pallets speed up busy-dock handling
• Confirm your equipment fits the pallet size range
• Whatever the type — strap the load to the deck

Pick the structure, entry, and material for your load and your dock, and make sure your equipment — and your strapping — handles the whole range.
