Mixed helical staircase with 9 alternate straight steps (5 initial and 4 final) built in a private house in Bologna in order to connect the ground floor to the first floor (one ramp).

The staircase is part of our Struktura series and has a diameter of 300-A, height H. 332 and a fine plaster finish.

Riser and tread steps cladding is made of grey porcelain stoneware.

STRUKTURA is manufactured in 15 standard diameters and features a closed tread and riser.

It is the sturdiest model as a result of the special structure of the internal section called “Ciklope”, which provides solidity and safety as well as a harmonious and sleek helical movement between the steps.

All our stairs are an exclusive European patent.
