Radial Sliding Doors


Round and curved sliding doors are ideally suited to lending any façade a real touch of style. They provide the unsurpassed elegance of a revolving door but are less complex and far more flexible with regard to looks. This type of door can be integrated into virtually any curved space and can be curved inwards or outwards.


  • Intelligent door automation – self-learning.
  • Safer, more reliable.
  • Economical – also thanks to variable opening widths, depending on frequency of use.
  • Aesthetically beautiful and strikingly quiet.
  • User-friendly – simple menu-led operation via text display in most languages.
  • Intelligent record presence detector senses persons in the door leaf area.
  • Can also be used in escape and rescue routes.
