Plywood is a material manufactured from thin layers of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. It is an engineered wood from the family of manufactured boards which include medium-density fibreboard (MDF) and particle board (chipboard).

A typical plywood panel has face veneers of a higher grade than the core veneers. The principal function of the core layers is to increase the separation between the outer layers where the bending stresses are highest, thus increasing the panel’s resistance to bending. As a result, thicker panels can span greater distances under the same loads. In bending, the maximum stress occurs in the outermost layers, one in tension, the other in compression. Bending stress decreases from the maximum at the face layers to nearly zero at the central layer.

Types of Plywood

  • Softwood plywood : Softwood plywood is usually made either of cedar, Douglas fir or spruce, pine, and fir (collectively known as spruce-pine-fir or SPF) or redwood and is typically used for construction and industrial purposes.
  • Block Board : Block Board are made by stocking the cubical wood between two thin sheets of ply. These wood are commonly used in the construction sites as they have got the higher resistance against bending and wrapping.
  • Decorative plywood : Decorative plywood or veneer is basically a thin slice of expensive grained wood. Or reconstituted wood stuck to a lesser expensive plywood, MDF, or particle board piece.
