Task force addresses questions regarding visually graded Southern Pine lumber

Answers address transition issues, how to obtain similar load-carrying capabilities, and why only some grades and sizes are affected at this time. 

February 10, 2012

The recent approval of the Southern Pine Inspection Bureau’s (SPIB) new design values for visually graded Southern Pine lumber by the American Lumber Standard Committee (ALSC) Board of Review has generated more questions among producers and customer groups.

The Southern Forest Products Association (SFPA) facilitated a task group of industry leaders representing key customer groups to develop answers to the most commonly asked questions regarding new design values and their implementation. This new collection of questions and answers is now available at www.southernpine.com.

SPIB issued Supplement No.9 to the 2002 Standard Grading Rules for Southern Pine Lumber providing new design values effective June 1, 2012.

The only design values that will change on June 1 apply to visually graded Southern Pine and Mixed Southern Pine sized 2 to  4-in-wide and 2 to 4-in-thick (2x2s through 4x4s) in No.2 and lower grades (No.2, No.3, Stud, Construction, Standard and Utility).

What about dense and nondense lumber?  What about prime lumber grades?  What happens between now and June 1?

These are among the new questions answered in SFPA’s updated web pages. A helpful table is included listing the new design values for Southern Pine and Mixed Southern Pine, effective June 1, 2012.

Answers address transition issues, how to obtain similar load-carrying capabilities, and why only some grades and sizes are affected at this time. More than two-dozen questions are answered in this updated collection, including a supplemental set of questions with answers providing important background information on this issue.

“The effective date of June 1 allows for an orderly transition to the new design values,” says Cathy Kaake, SFPA’s senior director of engineered and framing markets. “These answers address the most common questions raised since the ALSC’s decision earlier this month,” she adds.

 The Southern Forest Products Association (SFPA) continues to facilitate the dialog about new design values and their implementation. Between now and June 1, SFPA will provide more information as it becomes available; check www.southernpine.com frequently for updates. BD+C
