The Southern Forest Products Association (SFPA) has produced a new pocket span card for pressure-treated Southern Pine dimension lumber.

The laminated card measures 3.75” x 7.75” and contains three tables for treated floor and deck joists in nominal sizes ranging from 2×6 through 2×12.  Spans are listed for the visual grades of No.1, No.1 Prime, No.2 and No.2 Prime for the most common on-center spacings of 12, 16 and 24 inches.  Typical treated lumber quality marks are explained.

“This new card will be a handy field reference for the treated lumber spans needed for both raised floor foundations and decks,” noted SFPA’s Eric Gee.  “Marine and other outdoor building applications will also benefit from the information on this card,” he added.

Cards can be ordered from the Publications page of for $2 each; 50 or more are $1.25 each. Building code offices can receive five free cards upon request on official letterhead.
