Top deck boards
Thickness 16-22 mm, width 95-145 mm, length 800-1200 mm. The deck face that touches the load, sound and reasonably knot-free, planed or rough-sawn per spec. Pine and whitewood dominate, with KD-HT moisture content 18-22%.
Bottom deck boards
Thickness 16-22 mm, width 95-145 mm, length 800-1200 mm. Permits more knots than top boards but must still satisfy bending strength under racked load. The cost-saver line in the pallet, often a lower visual grade than the top deck.
Stringers (American-style two-way pallets)
Cross-section 22-38 mm × 95-145 mm, length 800-1200 mm. The longitudinal load-bearing member running between top and bottom decks. Notched for two-way fork entry on US-style pallets; full-section solid for four-way entry.
Bearers
Cross-section 35-45 mm × 70-100 mm, length 800-1200 mm. Cross-members supporting the deck above pallet feet, sized to bridge the block spacing without sagging under load.
Blocks
Standard EPAL dimensions 78×78×95 mm, 78×78×100 mm, 78×78×145 mm. Variants from custom pallet plants run 100×100×100, 100×145×95 and 145×145×78. Solid, finger-jointed and composite, see the dedicated block article.
