Plywood is the material that made from thin slices of wood (veneer) are stacked in layers until it reaches a certain thickness. Plywood consisting of consisting of 3 sheets of plywood veneer, while consisting of 5 sheets of veneer, or more commonly called a multiplex.
Thin sheets are brought together using adhesive / glue special. Various kinds of wood can be used to serve as plywood panels, both hardwood and softwood.
Plywood main strength lies in the fiber cross / perpendicular. So when the first sheets of horizontal fibers, the fiber pieces on it vertically, horizontally fiber on it again, and so on. This pattern provides rigidity and strength for the composition of the wood sheets to withstand the burden and slow the cracks.
Usually one sheet of plywood made from layers of wood in an odd number. So when the bottom layer of fiber horizontal, then vertical fiber on the top. Some plywood, is the outermost layer of wood with fiber / tendon that good. Plywood as this is usually used for transparent finish (shown natural fiber wood).
Compared to other processed materials such as teakblock (made of wood potogan glued), particle board (made of compressed sawdust), MDF or medium density fiberboard (made of wood powder compacted), plywood is a bit more expensive, but far stronger. These materials can be used for cabinets, racks, stairs, or even the floor. But however, the panels are sold in sizes 2440 mm x 1220 mm and the thickness of the common 4 mm, 6 mm, 9 mm, and 12 mm is not resistant when exposed to water. Because bonded using glue, when exposed to water constantly, this adhesive can escape.
Today, many people who use these materials for a variety of furniture, such as kitchen sets, bookshelves, or desk TV. So it looks beautiful, this material can be coated takon, veneer, PVC, or other coating materials.
