The stringer stairs are complemented by the horizontal balustrade stringers at the elliptical slab edges. Beside their exceptional shape there are however further convincing aspects characterising these stringer stairs. One of them are the tangentially designed connections of the single components at the rounded and curved sections which increase the smooth and harmonious appearance of the stringer stairs.
- 115 risers without intermediate landings
- construction according to DIN 18065
- flight width 1.380 mm
- floor-to-floor height approx. 4.000 mm
A high level of accuracy was required for the tread step construction as the overhang between the treads and risers only amounted to 2 mm. Another challenge was the evenly execution of the chamfer accross the whole tread width. The ascending handrail is installed corresponding to the geometry of the stringer stairs. It consists of a bent round tube and is connected to the outer stringer.
