Southern Pine Lumbers
Solid sawn pine wood products are classified in different ways, based mainly on use. “Dimension lumber” consists predominately of 2X4s, 2X6s, etc., and is produced for use as supporting members in building structures. Consequently, dimension lumber quality is based on predicted strength and stiffness, with higher quality (grades) expected to support heavier loads for the size. Wood products sawn for mainly decorative uses is generally categorized as “boards” and graded predominately for appearance. Higher grade boards contain fewer discolorations and discontinuities like knots or holes. “Poles” for supporting vertical loads are graded on size (height and diameter) and shape (straightness in particular) with strength considered too.
