ALSC Approves New Design Values for Southern Pine

Effective June 1, 2013
NLBMDA Sought Transition Period for Changes in Design Values

(Washington, D.C.) - The American Lumber Standard Committee's (ALSC) Board of Review has approved new design values for the remaining sizes and grades of visually graded Southern Yellow Pine dimension lumber.  Following recommendations from the National Lumber and Building Material Dealers Association (NLBMDA) and other stakeholders, the Board of Review has recommended a transition period for the changes with an effective date of June 1, 2013.
"NLBMDA is pleased that the Board of Review has listened to industry concerns about sudden changes in lumber design values and the impact they can have on the value of dealers' inventory and dealers' customers," said NLBMDA President Michael O'Brien.  "We believe a standard transition period will cause less disruption in the supply chain and give dealers time to plan for the changes."
The changes in Southern Pine design that went into effect on June 1, 2012 only applied to visually graded Southern Pine and Mixed Southern Pine sized 2" to  4" wide and 2" to 4" thick (2x2s through 4x4s) in No.2 and lower grades (No.2, No.3, Stud, Construction, Standard and Utility).  The changes taking effect June 1, 2013 make some changes to those grades and set new design values for the remaining sizes and grades.
"As the ALSC Board of Review now considers changes in design values for other species currently under review, we will continue to advocate for reasonable transition periods," added O'Brien.
The Southern Forest Products Association (SFPA) has detailed Q&As, as well as span tables based on the current and new design values at
