There is a shortage of smart serial produced stairs. There seems to be great interest in advanced interiors, especially for duplex apartments, where the staircase is an important part of the interior.
The principle of the stair is simple. The shape of an ellipse is actually a tilted circle and a staircase is usually leaning at an angle of 30 degrees for comfortable usage. If you use an elliptical beam with angled cuts, the elliptical cuts will create perfectly round circles. In our case, we have chosen a cast module of the beam at each step, with an integrated step attachment. This means that you can turn each module 360 degrees and orient the stairs freely as needed, from straight to the S-shaped or spiral shape. So simple and obvious when you see it.
