How it's built
The 7 top deckboards (22 mm thick) are nailed through 3 stringerboards into 9 blocks, 145 mm × 100 mm × 78 mm.
The base is unidirectional: bottom boards run one way only, 22 mm thick. The openings between the blocks take forklift tines from all four sides (full 4-way entry).
Nails follow the Uniform Standard for Wood Pallets minimum per joint by board width: 51 in the top deck and 21 in the bottom deck, 72 in total, 2-1/4 in helical.
