If the angles of the different sections of the handrail to be joined are known very precisely, they can be factory-made, at least with the help of computer-aided accounting and design as well as manufacturing units partially prefabricate. Practice shows, however, that it is precisely with such stairs that can be adapted accordingly to the inevitable tolerances on the building that the handrails must also be put together accordingly on the building.
  • the handrail supports that rise vertically in the stairwell and at the lower and upper end of the respective run are known from conventional stair manufacturing.
