It has three notched stringers (partial four-way entry), 7 top and 5 bottom deckboards with 5-1/2 in lead boards, stands about 4.75 in tall and uses about 13.5 board feet and 84 nails.

Why it matters

The 48x40 is the most common North American pallet footprint, reported at about 30% of new US wood pallets, and GMA-style construction is what "standard pallet" usually means in US grocery and retail. It is partial four-way: forklifts from all sides, pallet jacks from the ends.

Load ratings

Vendor capacity claims for GMA pallets vary widely, because the design is loosely specified and species and nails differ. Treat any single number as illustrative and ask for a rating in your support condition, from a PDS analysis or a test. palletdesign.ai shows an indicative rack check for each design.
