Hardwood plywood is a manufactured panel made up of 3 or more thin layers of wood veneer laid on top of each other and glued with the grain of each layer or ply running perpendicular to the one on either side of it. Hardwood plywood offers a strong, inexpensive, and environmentally responsible alternative to its solid wood counterparts.
Medium-density fiberboard (MDF), particleboard, combi-core, and lumber can also be used as cores. The predominate North American hardwood species are maple, cherry, red or white oak, hickory, ash, alder, walnut, and poplar.
