Construction structure c/d grade pine plywoodPlywood is a wood product manufactured out of many sheets of veneer, or plies, pressed together and glued, with their grains going
in opposite directions. It tends to be extremely strong, though not very attractive, and is treated in many different ways
depending upon its intended application. Because of the way in which plywood is constructed, it also resists cracking, bending,
warping, and shrinkage, depending upon its thickness. It is also referred to as an engineered wood, although it is made from a
composite of wooden materials.
