Block Pallets vs Stringer Pallets: Choosing the Right Foundation

Every pallet decision starts with a fundamental choice: block or stringer construction. These are not interchangeable options — they differ in strength, cost, weight, compatibility with handling equipment, and suitability for different supply chain applications. Understanding the difference saves money and prevents operational headaches.

Stringer Pallets

Stringer pallets use two or three parallel boards (stringers) running the length of the pallet to provide structural support. Deck boards are nailed across the top and bottom of the stringers. This is the most common pallet design in North America — the standard 48x40 GMA pallet is a stringer pallet.

Stringers provide two-way entry by default (forklifts access from the ends), but most stringer pallets include notches cut into the stringers to allow partial four-way entry. The notching allows forklift tines to enter from the sides, though with slightly less clearance than the full open ends.

Stringer pallets are lighter, cheaper to manufacture, and widely available in recycled form. They are the default choice for most domestic shipping applications, standard warehouse racking, and any scenario where cost efficiency matters more than maximum load capacity.

Block Pallets

Block pallets use solid wood blocks (typically nine — four corners, four edges, and one center) between the top and bottom deck boards. This construction provides true four-way entry with full clearance on all sides, making them easier to handle with both forklifts and pallet jacks from any direction.

The block design is inherently stronger. A well-built block pallet can support 5,500 pounds or more in dynamic loading, compared to roughly 2,800 pounds for a standard stringer pallet. They are also more durable — the block construction distributes stress more evenly, resulting in longer service life and fewer repairs.

The tradeoff is cost. Block pallets typically cost 25-50% more than equivalent stringer pallets due to additional materials and more complex assembly. They are also heavier, which can affect freight costs on weight-sensitive shipments.

When to Use Which

Use stringer pallets for standard domestic shipping, general warehousing, and any application where the GMA standard is expected. If your pallets are going into standard racking and your loads are under 2,500 pounds, stringer pallets are the cost-effective choice.

Use block pallets when you need maximum load capacity for heavy products such as beverages, building materials, or industrial equipment. They are also the better choice for automated warehouse systems where consistent four-way entry is critical, and for export shipments to European markets where block construction is the norm.

The Bottom Line

Do not over-specify. We regularly see buyers ordering block pallets for light-duty applications where stringer pallets would perform identically at a lower cost. Conversely, we see stringer pallets failing under loads they were never designed to carry. Match the pallet to the job. When you request through The Pallet Book, PalletMind factors in your load weight, handling requirements, and destination to recommend the right construction type — because the right pallet is not always the most expensive one.
