The spiral staircase DELTA from DOLLE is a straight-lined spiral staircase with anti-slip treads for those who want to combine design, colour contrast and comfort.
The staircase comes in anthracite powder-coated metal construction and anthracite painted treads gives it a beautiful, unique and contemporary design. The wide treads provide comfortable space and the single railing with continuous handrail ensures safe access.
The pitch height can be variably adjusted with spacer rings from 20,7 to 23,1 cm - depending on floor to floor height. The DELTA staircase is suitable for square ceiling openings thanks to the triangular landing platform that fits directly onto the ceiling area. It is possible to adapt the platform to suit round ceiling openings. It reaches a maximum floor height of 300 cm.
The DELTA spiral staircases come in both 120 cm and 140 cm - pick them in the dropdown here.
The spiral staircase Ø120 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.
