Plywood is a strong, versatile, and widely used building material made by gluing together thin layers of wood veneer. These layers, called plies, are stacked with their wood grain rotated at right angles to each other. This cross-graining gives plywood its strength, stability, and resistance to warping or cracking. Plywood comes in various thicknesses, grades, and types—designed for different uses such as furniture, flooring, walls, roofing, and even outdoor applications. It can be made from hardwood, softwood, or a mix of both, and is usually covered with a smooth finish or decorative veneer.
