Commercial Softwood Lumber
There are two major categories for commercial softwood lumber: construction lumber and lumber for remanufacture. Construction lumber is normally used in construction at the same size as it was graded. Grading for construction lumber is normally decided at the sawmill. No further grading occurs once the piece leaves the sawmill. On the other hand, lumber for remanufacture normally undergoes a number of additional manufacturing processes and reaches the consumer in a significantly different form.
