Bolted staircases are an especially modern type of staircases. They are sensationally self-supporting or bolted.
With this type of construction, the single stairs are combined one below the other with bolts. Sometimes for additional stabilizing they are mounted to the wall with wall anchors.
Bolted stairs can completely do without a supporting construction and impress with their filigree optic. Their type of design is suitable for straight staircases as well as for spiraled staircases.
