OSB (Oriented Strand Board) board, or particle board, is a type of engineered wood product made by compressing and layering strands of wood in different directions. The result is a strong and durable panel that is commonly used in construction, furniture making, and other applications where strength and stability are important. OSB board lumber is often preferred over traditional plywood because it is more cost-effective, easier to work with, and has a consistent surface quality. It is also more environmentally friendly as it uses smaller diameter trees and waste wood from sawmills, reducing the demand for large old-growth trees. Overall, OSB board lumber is a versatile and practical material that has become an increasingly popular choice for a variety of building and manufacturing projects.
