Plywood is a manufactured wood which is made by gluing several thin sheets of wood together with the grain alternately running along the sheet then across it.

A common reason for using plywood instead of plain wood is its resistance to cracking, shrinking and changing shape. It is used to make a range of things from sheds, to cladding to cabinets. It is graded on the quality, from class A to class D, A being the best quality and D being the worst quality.

There are two types of plywood: softwood and hardwood. They are used for different purposes.
