When sourcing pallets for your warehouse, distribution center, or manufacturing operation, one of the most fundamental decisions you will face is choosing between block pallets and stringer pallets. These two construction types differ significantly in structure, strength, handling flexibility, and cost - and the wrong choice can lead to equipment incompatibilities, damaged loads, or unnecessary expense.
This guide explains exactly how each pallet type is built, where each excels, and how to determine which construction is the best fit for your specific operation.
Stamped kiln-dried pallet lumber, bulk warehouse stock, dimensional yard inventory, raw softwood logs, and sawmill operations - the supply chain behind every custom and standard pallet we ship.

The real difference between block and stringer construction is not strength, it is how each one fails and what it costs to put back in service. A stringer pallet is cheaper and far faster to repair. A block pallet absorbs more repairs before it has to be scrapped. Which one is cheaper for you depends entirely on whether your pallets come back.
| Build or repair attribute | Stringer pallet | Block pallet | Why it matters |
|---|---|---|---|
| Load-bearing members | 3 stringers, nominally 1.38 x 3.5 x 48 in, running the 48 in length | 9 blocks, typically 3 rows of 3, joined by stringer boards | The stringer is one continuous piece. Crack it and the pallet loses a third of its support at once. A block pallet loses one of nine. |
| Top deck boards (GMA spec) | 7 | 5 to 7 over 3 stringer boards | Deck board count drives how well the pallet supports small-footprint cases without them sagging between boards. |
| Fasteners | About 84 helically threaded machine nails | Higher, because every block is fastened top and bottom | More joints means more assembly cost, and it is the main reason block construction carries a price premium. |
| Primary repair method | Plug the cracked stringer, or nail on a companion stringer alongside it | Replace the damaged block, which usually means pulling the deck boards and stringer boards attached to it | This is the single biggest practical difference. A stringer repair is minutes; a block repair is a partial teardown. |
| Typical repair input cost | About $0.50 to $1.25 in materials plus 3 to 6 minutes of yard labor | About $1.00 to $2.00 in materials plus 8 to 15 minutes of yard labor | Derived from published pallet repair material costs of $0.50 to $2.00 per pallet and pallet yard labor of $12 to $18 per hour. These are input costs, not a quoted rate card. |
| Effect on service life | Baseline for open, non-pooled use | Roughly 20 to 30 percent longer, because individual blocks are replaceable without condemning the pallet | The longer life is why pooling operators standardize on block construction: the same pallet is cycled many times and repaired repeatedly. |
| What fails first | Stringer cracks at the fork entry notch, and lead deck board breakage | Block separation from the stringer board, and bottom deck board loss | Notch cracking is the classic stringer failure and it is caused by forks entering the notched side. It is the reason a notched stringer is not a true four-way pallet. |
| Repairability verdict | Faster and cheaper per repair | Survives more total repairs before condemnation | Stringer wins on cost per repair. Block wins on how many repairs the pallet can absorb over its life. |
Repair cost figures are derived, not quoted: they apply published pallet repair material costs of $0.50 to $2.00 per pallet and pallet yard labor of $12 to $18 per hour to the labor time each repair method actually takes. Your delivered repair price will differ by volume, region and lumber index. Ask for a quote.
Rule of thumb: if pallets leave your dock and do not come back, the repair advantage of block construction is worth nothing to you and you are paying a premium for a benefit the next owner collects. If you run a closed loop or a pooled program, the longer repairable life is the whole point.

Block pallets use 9 wood blocks in a 3x3 grid to support the deck boards, while stringer pallets use 3 or 4 parallel boards running the length of the pallet. Block pallets allow full four-way fork entry from all sides; stringer pallets typically allow two-way entry or limited four-way entry with notched stringers. Block pallets are stronger and preferred for food grade, pharmaceutical, and high-cycle racking applications. Stringer pallets are less expensive and dominate the recycled pallet market.
