Block vs stringer pallets: differences and when to use each

Summary

Choose a stringer pallet when you want the lowest cost, one-way or closed-loop use and mostly 2-way handling. Choose a block pallet when you need true 4-way entry for forklifts and pallet jacks, heavy reuse, pooling, automation or the European 1200 × 800 footprint.

The difference is what sits between the top and bottom decks. A stringer pallet uses two or more continuous beams, the stringers, running the full length. A block pallet uses nine (sometimes more) blocks with stringerboards tying them together. That one choice changes fork entry, strength behavior, cost and repair.

Side-by-side comparison

Stringer pallet Block pallet
Structure 2–4 full-length stringers (3 typical on a 48 × 40 in) 9 blocks (3 × 3) plus stringerboards
Fork entry 2-way; partial 4-way with notched stringers Full 4-way for forklifts and pallet jacks
Typical 48 × 40 in weight about 30–50 lb (14–23 kg) about 50–70 lb (23–32 kg)
Bottom deck Boards across the stringers Boards in one direction, perimeter or cruciform
Racking Strong spanning along the stringers; weaker across More even in both directions
Repair Simple; stringers can be replaced or plated Blocks and stringerboards replaceable; more parts
Pools and exchange White-wood exchange (GMA style) CHEP, PECO pooled 48 × 40; EPAL and CP pallets
Relative cost Lower Higher

Weights are typical ranges for new hardwood or mixed-species builds and vary with species, moisture and board sizes. See how much a pallet weighs.

How they carry load

A stringer pallet behaves like two or three beams. When the stringers span between rack beams (beams under the stringer ends), the stringers carry the load efficiently. When the pallet is turned so the beams run parallel to the stringers, the deckboards must span the gap and capacity drops sharply. Notches cut for fork entry also take material out of the stringer at the point where bending is highest, which is why notch depth and length are controlled in the Uniform Standard for Wood Pallets.

A block pallet carries load through the stringerboards into the blocks. Its behavior is similar in both directions, which makes it more predictable in racking and in automated systems where the pallet may arrive turned. Blocks also resist the side impacts that break stringers, so block pallets usually survive more trips.

Neither type has a fixed capacity. The rating comes from the design (species, grade, board sizes, fasteners) and the support condition. See pallet load capacity.

Handling and fork entry

  • Stringer: forks and pallet jacks enter from the two ends. With notched stringers, forklift tines also enter from the sides, but a pallet jack cannot, because its wheels need gaps in the bottom deck. This is partial 4-way entry.
  • Block: all four sides have full-height openings, and bottom deck layouts are designed so pallet jack wheels reach the floor from at least two sides, often all four.

If your warehouse turns pallets frequently, uses pallet jacks on both faces or loads trailers sideways, block pallets save time. See two-way vs four-way pallets.

Cost

Stringer pallets are cheaper to build: fewer parts, simpler assembly, and every US pallet shop can make them. A new 48 × 40 in GMA-style stringer pallet is roughly $10–25 in 2026 US estimates, moving with lumber prices, volume and specification. Block pallets use more pieces and labor and usually cost more per pallet. Buying used lowers both; see pallet cost.

For one-way shipping, stringer usually wins on cost. For many trips, block pallets can cost less per trip because they last longer and repair well. Pooled block pallets are rented, not bought; see pallet pooling.

When to choose each

Choose a stringer pallet when:

  • the pallet is one-way or used in a short closed loop;
  • handling is mostly from the ends, or partial 4-way is enough;
  • you need a custom size quickly from local shops;
  • lowest purchase price matters most.

Choose a block pallet when:

  • you need full 4-way entry for pallet jacks;
  • pallets go through racking in both directions or automated systems;
  • the customer requires pooled pallets (CHEP, PECO) or EPAL / CP pallets;
  • pallets make many trips and you can recover them.

Specifying it for a quote

Put the class (stringer or block), footprint, entry (2-way, partial 4-way, 4-way), deck boards, stringer or block sizes, species, fasteners, load and support condition, and heat treatment on the RFQ. See the pallet RFQ checklist. You can open a block pallet in the designer or start from the GMA stringer template.

Frequently asked questions

Is a GMA pallet a block or stringer pallet?

Traditionally the GMA 48 × 40 is a stringer pallet with three notched stringers. The pooled 48 × 40 pallets used by major grocery suppliers today are block pallets built to the same footprint.

Which is stronger, block or stringer?

Neither by default. Capacity depends on species, board sizes, nailing and how the pallet is supported. Block pallets are usually more consistent in racking across both directions and hold up better to repeated handling.

Can a pallet jack enter a stringer pallet from the side?

Not on a standard notched stringer pallet. Forklift tines fit through the notches, but pallet jack wheels hit the bottom deckboards. That is why notched stringer pallets are called partial 4-way.

Are block pallets more expensive?

Usually, yes. They use more components and more labor per pallet. For multi-trip use the lower cost per trip can offset the higher purchase price.
