plywood vs wood

1) Expensive timbers go further. A cheap timber can be used for the core, with the expensive timber used on the outside.
2) The size of plywood is not restricted by the size of the tree it came from, but the size of the press table used to make it.
3) Solid wood is 20 times stronger along the grain than across. Plywood over 10mm thick is almost equal in strength in both directions.
4) Timber shrinks mostly across the grain. Shrinkage is almost eliminated in plywood due to the layers being in alternate directions.
5) Plywood can be formed or bent to make a curve.
6) Plywood does not split at the edges when nailed or screwed.

Advantages of plywood:

* Environmental Investment – It is a natural product made from a renewable resource. Therefore, it is one of the most environmentally friendly decorative products available to the consumer.

* Strength – Pound for pound, plywood is stronger than steel in static bending strength. What makes plywood so strong is its unique cross-layered structure. The adhesives used to bond the veneers in plywood are actually stronger than the wood itself.

* Efficiency – The plywood manufacturing process achieves a more complete utilization of the log than does lumber manufacturing. No sawdust results from either rotary cutting or slicing (the two most popular methods of cutting veneer). Greater square foot coverage, in comparison to solid wood products, is achieved by using veneer. Thus, plywood manufacturing makes better use of the high value woods prized by consumers today.

* Beauty – Architects and designers prefer the beauty of wood over any other material. The natural characteristics of wood make it attractive to the eye. Wood defies imitation. No material can match the infinite variety of natural markings and figure patterns offered through fine hardwood.

* Versatility – A great variety of products in various shapes and sizes can be manufactured from hardwood plywood. Chair backs and seats, domes, bowling alley channels, and pianos are just a few of the many various curved plywood products.

* Durability – In museums all over the world are ancient examples of plywood furniture and decorative veneers that have lasted hundreds of years.
