NOTE: Click here for additional background information regarding design values.
These easy-to-use tables were compiled by the Southern Forest Products Association (SFPA) as a service to design/build professionals and other Southern Pine users.
Reference design values are for normal load duration under the moisture service conditions specified. SFPA does not grade or test lumber, and accordingly, does not assign design values to Southern Pine lumber. The design values contained herein are based on the Southern Pine Inspection Bureau’s Standard Grading Rules for Southern Pine Lumber and modified as required by the American Wood Council’s National Design Specification® (NDS®) for Wood Construction. Accordingly, neither SFPA, nor its members, warrant that the design values on which the span tables for Southern Pine lumber contained herein are based are correct, and specifically disclaim any liability for injury or damage resulting from the use of such span tables.
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.
