Book excerpt: Excerpt from Potential for Producing Ponderosa Pine Plywood in the Black Hills A major advantage of producing plywood in the Black Hills area of South Dakota and Wyoming is prox imity to major markets. Plywood produced there could be delivered to Great Plains and upper Midwest markets at a freight cost lower than that from other major softwood plywood producing regions. Market potentials for softwood plywood in the United States are very strong for the foreseeable future. However, because ponderosa pine is not a well established plywood species, there is some question about the share of the market it can command. Because Black Hills ponderosa pine yields primarily C and D grade veneers, its utilization would be limited mainly to plywood products made from these grades, such as roof and wall sheathing, siding, or flooring. Other special plywood products for use in new residential, homeowner, nonresidential construction, and indus trial markets seem promising also. Small volumes of B Patch and better veneer might be marketed as stock for products where appearance is of some importance, such as cabinets. In addition, recent developments in performance standards for sheathing panels, including plywood, may have expanded market possibilities for woods such as ponderosa pine. Performance-rated sheathing panels are designed, manufactured and identified for specific construction end uses (american Plywood Association Such panels conform to criteria for panel strength, stiffness, durability, stability and other properties relevant to the end-use. If structural criteria are met, panels can be made entirely from veneer faces bonded to a reconstituted wood core, or from reconstituted wood. In the case of plywood manufactured from ponder osa pine in the Black Hills, the provisions of Product Standard 1-74 (american Plywood Association 1974] remain applicable. However, it is possible that such plywood could now obtain upgraded span ratings through testing for sheathing end-use applications. See the appendix for details about sheathing applications and span ratings. Plywood variables such as veneer thickness and orientation, along with inherent wood properties, would determine in part how well such panels meet the standards for performance-rated sheathing.
