Stringerboard
Also called: stringer board
Reviewed
A stringerboard is a full-length board on a block pallet that sits between the deckboards and the blocks and ties the blocks together, specified as thickness x width x length. The EPAL 1 Euro pallet uses three 22 x 145 x 800 mm stringerboards.
How stringerboards are specified
Stringerboards are stated like deckboards, as thickness x width x length. They run the full pallet length on block pallets, one over each row of blocks.
| Example | Stringerboards |
|---|---|
| EPAL 1 (1200x800) | 3 x 22 x 145 x 800 mm |
| PDS metric example (1200x1000) | 3 x 18 x 95 x 1200 mm |
Block pallets can have top stringerboards only, or top and bottom stringerboards (the overlap base). PDS also models trenched (dadoed) stringerboards that accept recessed deckboards.
How the deck is built
The top deckboards and stringerboards are often pre-assembled into a deck mat with clinched mat nails, then nailed down through the stringerboard into the blocks.
Stringerboard vs stringer
A stringer is a solid beam, typically 3-1/2 in or more tall, that spaces the decks apart on its own. A stringerboard is only a board: the blocks provide the height and the fork openings, which is what makes a block pallet enterable from all four sides.
Questions
- Do stringer pallets have stringerboards?
- No. Stringerboards belong to block pallets. A stringer pallet uses solid stringers instead.
