Spiral staircase with a lateral stringer (metal frame and wooden steps)
ELI AC
RIZZI
The helicoidal shape gives the staircase an elegant and aerial appearance, making it unique in natural essence and absolute technical reliability.
The helicoidal staircase is made up of monolithic elements and it has no central support column. This is an important feature that leaves plenty of space at hand and shoulder height and facilitates the transport of bulky objects, even on low-diameter staircases.
