SOFTWOOD LUMBER

Many Western species share similar performance properties and are grown, harvested and manufactured together. These products are marked as a species combination to simplify marketing, design and engineering and allow design values to be assigned under a group rather than as individual species.

Western dimension lumber is manufactured in both single species and species combinations.  Douglas Fir, Ponderosa Pine, White Fir and Western Red Cedar are the most common single species sold as dimension lumber products.   

Structural lumber (including dimension lumber) is visually and/or mechanically (MSR) graded for its strength and physical working properties (appearance is secondary, unless specified). Basic end-use classifications are organized by size classifications and performance capabilities
