Specific Gravity Correction Value Sources

This specific gravity (SG) correction value was developed by Wagner Meters. These values are based on our research and have been developed to give users a general correction factor for plywood & oriented strand board (OSB). Please keep in mind that plywood & OSB manufacturing processes can differ slightly and some plywood and OSB of the same species may vary slightly.
