Economy Grade OSB (Falldown)
OSB Economy Grade
OSB is manufactured according to strict grading guidelines, so naturally there will be reject grades that are pulled out of production runs. OSB can fail to make grade due to a variety of reasons, being that the panel might not be dense enough, strong enough, have a delamination or blow out, or missing edges. Even though the panel does not meet the guidelines for use in construction, a large percentage of the panel is usable and still useful in a variety of packaging and industrial manufacturing applications.
