Finding alternative uses for small diameter raw materials is a critical problem throughout the United States. Insufficient markets for small diameter, southern yellow pine (Pinus spp.) trees from first plantation thinnings are impacting silvicultural practices on millions of acres of land. In western states, the lack of markets for small diameter ponderosa pine (Pinus ponderosa) and lodgepole pine (Pinus contorta) creates multiple problems in terms of excess material in the forest. This excess material enhances fire potential and reduces land management practices. This research deals with a new structural composite from small diameter raw logs using a technology called steampressed scrim lumber (SPSL). Mechanical and physical properties were performed and evaluated for each species. This research was conducted to evaluate these properties and to determine the suitability for commercialization
