Disclaimer:

Southern Pine design values are published by the Southern Pine Inspection Bureau in the SPIB Standard Grading Rules for Southern Pine Lumber after approval by the Board of Review of the American Lumber Standard Committee. The Southern Forest Products Association (SFPA) does not test lumber or establish design values. Accordingly, neither SFPA, nor its members, warrant that the data or design values herein are correct, and disclaim responsibility for injury or damage resulting from the use of such design values.

Reference design values are based on normal load duration and dry service conditions. Because the strength of wood varies with conditions under which it is used, these design values should only be applied in conjunction with appropriate design and service recommendations from the National Design Specification® (NDS®) for Wood Construction published by the American Wood Council.

The conditions under which lumber is used in construction may vary widely, as does the quality of workmanship. Neither SFPA, nor its members, have knowledge of the quality of materials, workmanship or construction methods used on any construction project and, accordingly, do not warrant the technical data, design or performance of the lumber in completed structures.
