Helical Staircases

Rintal’s helical staircases, thanks to their shape, decorate the space with sinuous elegance and lightness.

Characterized by the absence of the central pole, helical staircases make walking on them easier and leave ample room for the passage, especially at hand- and shoulder-height, thus favoring the passage of bulky items even on stairs with small diameters.
