For the 20-storey stock exchange building, designed by KSP Engel & Zimmermann, Bauporte developed 3 fully automatic revolving doors.
The round shapes of the 4-winged Circular Prestige seamlessly flow into the facade of the cube-shaped building.
For maximum security, the curved panels close off the entrance completely at night. During the day, these disappear into the curved walls of the entrance.
The 6.5-metre-high revolving doors were installed to be entirely freestanding and are only in contact with the building through flexible seals.
Three self-supporting design revolving doors were installed in the stately reception hall
