OSB, or oriented strand board, is a type of engineered wood panel made by compressing and gluing together small strands or flakes of wood in a specific orientation. It is similar to plywood but uses strands of wood instead of thin veneers.

The strands in OSB are typically arranged in three layers, with the outer layers oriented perpendicular to the inner layer. This cross-oriented construction gives OSB its strength and stability, making it a popular choice for construction and building applications.

OSB is commonly used as a sheathing material for walls, roofs, and floors, as well as in the manufacture of furniture and other wooden products. It is known for its affordability, durability, and versatility, and is often used as a substitute for plywood in many applications.
