The spiral staircase SIGMA has got 12 treads in lamellar lacquered beech including a triangular landing platform at the top - also in lamellar lacquered beech. The 12 treads plus landing gives 13 risers and a maximum height of 309 cm. Adjustable for all smaller heights. The banister is grey lacquered metal with 4 balusters on each tread, which also makes the staircase save – even though it has open risers. If you prefer this spiral staircase with black handrail and balusters you should have a look at the KAPPA spiral staircase.
Sculpture beauty - easy to install with minimal heavy components. No special tools are required.
The spiral staircases come in both 120 cm and 140 cm - pick them in the dropdown here.
To give an example the spiral staircase SIGMA Ø 120 cm only requires an opening of 125 cm x 125 cm or a round ceiling opening of 130 cm. In general, subtract 10 cm from your ceiling opening to get the right diameter of your new staircase.
Please consider window or door locations with stop inside or outside as well radiator locations to prevent assembly issues. For wall niches please note the entry and exit points and be aware the optimal ceiling opening is 10 cm larger than the staircase diameter.
Extra tread (2 treads max) and balcony balustrade 140 cm – please call or office for further assistance.
Height till landing: max. 309 cm
Adjustable spacer from 22-23.8 cm
