From one of the largest pressure treated wood companies in the U.S., Industry experts say Southern Yellow Pines density makes it the strongest softwood structural lumber species. Changes may be a coming as earlier this year the Southern Pine Inspection Bureau (SPIB) sent shock waves through the construction industry when it revealed it had submitted new, substantially lower design values for visually graded southern pine dimension lumber to the American Lumber Standard Committee (ALSC) for review. Forest Products Society, Madison, WI. I found this recently at www.spib.org: The Family owned and publicly traded companies that choose to use the SPIB logo on their Products represent the best of the lumber producers. ASTM (2013) D 4761-13 Standard test methods for mechanical properties of lumber and wood-base structural material.

While the cold formed steel industry is quick to throw stones at southern yellow pine lumber, the revision in design values does not affect machine stress rated or machine evaluated southern yellow pine which is heavily used in the prefabricated wood truss, glu-lam and I joist industries. SPIB also proposed a 200,000 psi reduction in the modulus of elasticity for southern pine. I do a lot of research on most everything I blog about.
