Freestanding staircases are often found in residential construction made from wood or metal and sometimes concrete. The term means that they are not supported by a central column but stand free, supporting their own weight.
When built in wood, the sringers are laid up of glued strips of wood, shaped and clamped to a form. They are similar in appearance to LVL manmade beams, though often better looking because of exposed edges in many applications.
