Stringer pallet: construction, dimensions and when to use one

Summary

A stringer pallet is a wooden pallet whose deckboards are nailed across two or more continuous beams called stringers, usually three on a 48 × 40 in pallet. It is 2-way entry, or partial 4-way when the stringers are notched. It is the most common and cheapest pallet design in North America.

The stringer pallet is the workhorse of North American shipping. It has fewer parts than a block pallet, it is fast to build on automated nailing lines, and it can be made to almost any size. Most one-way and closed-loop wooden pallets in the US are stringer pallets.

What is a stringer pallet?

A stringer pallet is a pallet built on stringers: continuous lumber beams that run the full length of the pallet. Deckboards are nailed across the stringers on top and usually on the bottom. By North American convention, the stringer length is the pallet's first dimension, so a 48 × 40 in pallet has 48 in stringers and 40 in deckboards.

How is a stringer pallet built?

A standard 48 × 40 in stringer pallet has three component groups. The values below are from a typical GMA-style design.

Component Count Typical size (in) Metric (mm)
Top lead deckboards 2 5/8 × 5-1/2 × 40 16 × 140 × 1016
Top interior deckboards 5 5/8 × 3-1/2 × 40 16 × 89 × 1016
Stringers 3 1-3/8 × 3-1/2 × 48 35 × 89 × 1219
Bottom lead deckboards 2 5/8 × 5-1/2 × 40 16 × 140 × 1016
Bottom interior deckboards 3 5/8 × 3-1/2 × 40 16 × 89 × 1016
Overall height 4-3/4 121

The two outer stringers sit flush with the pallet edges and the centre stringer is centred. Top boards are usually spaced evenly with the lead boards flush to the ends; in the design above the gaps are 3.25 in (83 mm). The fastener schedule is typically 3 nails per joint for 5-1/2 in lead boards and 2 per joint for 3-1/2 in boards, giving 84 nails per pallet.

Notches and partial 4-way entry

A notch is a cutout in the bottom edge of each stringer so forklift tines can enter from the sides. The Uniform Standard recommends an opening about 2 in (51 mm) high (notch depth plus bottom deckboard) and 9 in (229 mm) long, with a radiused profile and at least 7 in (178 mm) of flat top between notches. Square notches are not acceptable. Bottom deckboards are placed so they do not cover the notches.

With notches, a forklift can enter from all four sides, but a pallet jack can only enter the two ends. The pallet is then partial 4-way. Without notches it is two-way.

Where are stringer pallets used?

Stringer pallets carry most one-way and in-house loads in North America: grocery and consumer goods, building products, bagged goods, paper, beverages and industrial parts. They suit custom sizes because only board lengths change. Retail distribution often specifies the GMA pallet, while pooled programs (CHEP, PECO) use block pallets.

Pros and limits

Pros Limits
Lowest cost wooden design Pallet jacks enter from two sides only
Easy to build in any size Notches weaken stringers
Easy to repair (companion stringers, new boards) Less stable in racking across the width than many block designs
Light for its strength Deckboard ends can split when forks strike them

Weight and capacity

A 48 × 40 in stringer pallet usually weighs 30–70 lb (14–32 kg). Species and moisture drive the spread. Capacity depends on how the pallet is supported:

  • Stacked on a flat floor, a well-built 48 × 40 can carry several thousand pounds.
  • Racked across its length (stringers spanning the beams) it carries much less, and racking across the width (deckboards spanning the beams) is often the weakest case.
  • Notched stringers lose section at the notch, which reduces racking strength across the length.

One published analysis of a GMA-style design rated it 1,558 lb (707 kg) racked across the length and 5,223 lb (2,369 kg) stacked one high. Treat such numbers as examples only. The manufacturer's PDS analysis or ASTM D1185 test is authoritative for a given design. See pallet load capacity and racking and deflection.

ISPM 15

Stringer pallets are solid wood, so they need heat treatment and an ISPM 15 mark for most export. Domestic loads do not. See heat-treated pallets.

What drives the cost?

  • Board feet: the GMA-style design above uses 13.5 board feet at actual dimensions. Thicker decks, more boards or a fourth stringer add lumber.
  • Species: SPF and SYP are usually cheaper per board foot than dense hardwood, but prices vary by region.
  • Notching: a machining step, usually small.
  • Heat treatment and kiln drying.
  • Volume and freight.

As a 2026 US estimate, a new standard 48 × 40 costs about $10–25, and prices move with lumber markets. The board feet calculator shows how lumber volume changes with the design.

Frequently asked questions

How many stringers does a pallet have?

A 48 × 40 in stringer pallet normally has three. Heavy-duty or wide pallets use four or more, and narrow pallets such as the 48 × 20 in half pallet use two.

What size is a pallet stringer?

Hardwood stringers are commonly 1-1/4 or 1-3/8 × 3-1/2 in (32 or 35 × 89 mm). Softwood stringers are usually 2 × 4 lumber at 1-1/2 × 3-1/2 in (38 × 89 mm). Length equals the pallet length.

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

No. Notches let forklift tines enter from the sides, but a pallet jack needs its wheels to reach the floor, and the bottom deckboards block that. That is why notched stringer pallets are called partial 4-way.

Is a stringer pallet the same as a GMA pallet?

A GMA pallet is one specific stringer pallet: 48 × 40 in, three notched stringers, seven top and five bottom deckboards. Stringer pallets come in any size and board layout.
