It is also known as a transport in Canada; prime mover in Australia; semitractor-trailerbig rig, or 18-wheeler in the United States; and articulated lorry, abbreviated artic, in Britain and Ireland. No matter what you call it, Keruing or Apitong wood is the most popular hardwood used to make wood trailer or truck decks for semi-trailers.
