Actually, there are many prefabricated metal spiral stairs that are built on a column. What is meant by "free standing" is that the stair is not supported by the building's structure. It's bolted to the floor slab and attaches at the upper floor, but, other than that, it's not supported by the structure itself, hence the term "free standing." Such stairs can be installed, fully assembled at the factory, and that, coupled with the fact that they can be located anywhere, is waht makes them so atractive.
