What material is created by gluing thin sheets of wood together with grains at right angles?

Plywood is created by gluing thin sheets of wood, known as veneers, together with the grains of each layer oriented at right angles to one another. This cross-lamination process significantly enhances the wood's strength and stability, reducing the risk of expansion or contraction due to moisture. The alternating grain direction of the sheets helps to distribute tension and stress evenly across the material, making plywood a durable and versatile choice for various applications, including furniture, construction, and cabinetry.

In contrast, particle board is made from wood chips, sawmill shavings, or sawdust that are bonded together with adhesives, while laminate involves a thin layer of material applied to a surface for aesthetic purposes, and hardwood refers to solid wood that comes from deciduous trees. Plywood stands out for its structural integrity, which is a direct result of the way the sheets are layered and glued.
