Plywood is manufactured in many variations. Plywood is used to build furniture, cabinets, concrete forms or any other construction project that requires large, flat pieces of wood. Plywood is created by placing thin layers of wood with glue under extreme pressure in hydraulic presses to create a single sheet of wood. Softwood plywood is typically used for structural building and construction applications. Hardwood plywood is used for furniture and cabinets.
Aircraft grade plywood, often Baltic birch, is made from 3 or more plies of birch, as thin as 1/64 thick in total, and is extremely strong and light. At 3/8 thick, mahogany 3-ply wiggle Board or Bendy Board come in 4' x 8' sheets with a very thin cross grain central ply and two thicker exterior plies, either long grain on the sheet, or cross grain.
