New Design Values

June 01, 2012

June 1, 2012

The Southern Pine Inspection Bureau (SPIB) has issued Supplement No. 9 to SPIB’s 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” wide and 2” to 4” thick (2x2s through 4x4s) in No.2 and lower grades (No.2, No.3, Stud, Construction, Standard and Utility). SPIB is in the process of submitting new design values for No.2 Dense and No.2 NonDense to the Board of Review of the American Lumber Standard Committee for approval. The new design values for No.2 Dense and No.2 NonDense will also become effective June 1, 2012.

Design values for all other grades and sizes of visually graded Southern Pine remain the same, pending results of testing scheduled for completion later in 2012.

Effective June 1, 2012 — New Design Values: Only No.2 and Lower Grades
