Plywood  is a sheet material manufactured from thin layers or "plies" 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 includes  medium-density fibreboard  (MDF) and  particle board  (chipboard). 

 All plywoods bind resin and wood fibre sheets ( cellulose  cells are long, strong and thin) to form a  composite material . This alternation of the grain is called  cross-graining  and has several important benefits: it reduces the tendency of wood to split when nailed at the edges; it reduces expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across all directions. There are usually an odd number of plies, so that the sheet is balanced—this reduces warping. Because plywood is bonded with grains running against one another and with an odd number of composite parts, it is very hard to bend it perpendicular to the grain direction of the surface ply. 

Smaller thinner plywoods and lower quality plywoods (see Average-quality plywood photo below and right) may only have their plies (layers) arranged at right angles to each other, though many better quality plywood products will by design have five plies in steps of 45 degrees (0, 45, 90, 135, and 180 degrees), giving strength in multiple axes.

Benefits include:
  • High uniform strength  
  •  Freedom from swelling and warping 
  •  Non-splitting qualities 
  •  Availability of large sizes 
  •  Economical and effective utilisation of figured wood 
  •  Greater dimensional stability Ease of fabrication of curved surfaces Conservation of timber by eliminating waste and defects
