Stairs are made in two or more pieces to get into a smaller area or to be taken up an elevator. Often sufficient space is not available to get a fully assemble staircase in place. Space limitations often happen in doorways, hallways and elevators. One solution to such limitations is to "splice" a staircase. Simply, the stair is fully manufactured and assembled and then a splice is created to reduce the height of the staircase to fit through the obstacle. The stair is then carted in and re-assembled at the job site. A local welder would then make the necessary weld seems to secure the stair. Splicing is also used extensively when it is necessary to weld several complete staircases to get the required height.
