Oriented Strand Board (OSB) is a type of engineered wood panel made by compressing and binding strands of wood together with adhesive under heat and pressure. The strands are typically arranged in cross-oriented layers, which enhances the panel's strength and stiffness. OSB is widely used in construction and renovation projects as a structural panel for walls, floors, and roofs, offering similar applications to plywood but with distinct characteristics.

Key features of OSB include its affordability, dimensional stability, and consistent quality due to its manufacturing process. It's available in different grades and thicknesses, suitable for various applications ranging from sheathing in residential and commercial buildings to packaging and furniture production.
