The spiral staircase Tours, with a diameter of 140cm, is a sturdy industrial spiral staircase in cast iron with a very comfortable rise (17.5cm per tread). The staircase is suitable for both indoor and outdoor installation due to the fact that the treads are perforated which allow the water to pass through. The staircase is available turning anti-clockwise with a speed of 14 steps per full turn (25,714 degrees per tread).
The height can be determined by multiplying the number of treads. The height of a tread is 17.5cm.
The diameter of the staircase is 1400mm, which is the outside diameter, handrail included. Ideally the stairwell is of the same dimension, but can be larger as well. The staircase is available turning anti-clockwise with a rotation speed of 14 treads to the circle (360 degrees turn).
The staircase weighs about 26kg per tread, all elements included.
The landing is the last tread, the exit of the staircase, connecting the staircase to the upper floor. Three shapes are standard available: 1/6 round, straight corner and triangular. If needed, a bespoke landing can be made.
The staircase is delivered in raw loose parts without finish. It is up to the client to choose the desired finish: either to keep the raw appearance of the metal, to wax or to paint. A (metal) wax or matt paint (anthracite grey or black) can be ordered and delivered with.
To make a balustrade (to secure the stairwell) there are additional balusters available. Calculate the number of balusters you need depending on the distance you want to keep between the balusters.
