Geze

GEZE is a German, family-owned global manufacturer of door, window, and safety technology, best known in the trade for door closers, automatic door systems (sliding/swing/revolving), window drives, and smoke & heat extraction (SHEV) solutions used in modern building safety and automation. 

Founded in 1863, GEZE remains independently owned and headquartered in Leonberg, near Stuttgart - one of the reasons it’s often described as a “proper engineering company” rather than a brand label slapped on a catalogue. 

In practical terms, GEZE lives in the space where comfort meets compliance:

• Door closing: from standard overhead closers to integrated systems for higher-spec doors and fire/smoke applications. 

• Automatic entrances: operators for swing and sliding doors used in public buildings, retail, airports, offices—accessibility and flow without sacrificing safety. 

• Safety + building automation: electrically operated window systems for natural ventilation and for smoke and heat extraction in a fire, plus increasing emphasis on digital networking of doors/windows in “smart building” setups. 

Scale-wise, GEZE states it has 3,000+ employees worldwide, 37 subsidiaries, and reported €507m+ turnover (FY 2022/23) - big enough to be everywhere, still small enough to feel focused.
