In this respect, GU Automatic GmbH is committed to being your competent and reliable partner.

Sliding doors


Automatic sliding doors are easy and convenient to pass through, meaning they are scarcely noticed by those using the building. They provide a modern entrance solution for public buildings, airports, train stations, shopping centres, banks, hospitals, retirement homes and homes for the disabled. With their compact and slimline design and their drive height of just 100 mm, the sliding doors from the compactMaster series do not just provide reliable functionality, but are also extremely attractive and elegant. Conflicting directives are reconciled with the HM-F FT escape route sliding door. The type-tested escape route sliding door guarantees a secure escape route, even when locked.Sliding doors


Revolving doors


Revolving doors are used wherever impressive entrances are needed. They are primarily used to provide public buildings, hotels, banks, insurance offices or airports with a striking entrance. Security revolving doors and security curved sliding doors are used for any entrance that requires extra security. In particular, they provide banks, insurance offices, government ministry buildings, authorities, data centres, industrial plants or office buildings with extra security and convenience.Revolving doors


Swing-door drives


Automatic closing is desirable with fire and smoke protection doors. However, a closed door always represents an obstruction. Nevertheless, convenience and accessibility can only be ensured if the door is easy to open. Automatic swing-door drives from the GU Group ensure secure closure yet allow convenient access via the radar motion sensor, push-button or access control system. Entrance doors in the facade can also make use of the benefits of the swing-door drive: when combined with multi-point locking, burglar protection and escape route safety are equally possible as well as ensuring accessibility.Swing-door drives


Glass sliding panels


Elegant appearance, flexible in terms of use of space and minimal space requirements: the benefits of glass sliding panels are most evident in public areas. As partition walls, the glass sliding panel systems from the GU Group offer modern solutions that combine maximum accessibility with a high level of versatility.Glass sliding panels

Controlling access to company premises, automatically controlling admission tickets and directing large numbers of people into ordered lanes: by offering high-quality products for controlled physical access, GU Group is making a real difference to the security of buildings and their users and offers suitable and visually appealing solutions for every area
of application.Controlled physical access systems


Door closer


If you are familiar with door clo­sers, you will quickly conclude that with GU pro­ducts, it's quality that counts. The clo­sing action is controlled hydrau­li­cally. Clo­sing force and clo­sing speed can be adjusted depending on the door leaf size and weight. The ver­sa­tile range of GU door clo­sers comprises overhead door clo­sers and floor springs as well as special solu­tions for hold-open sys­tems for 1-leaf and 2-leaves doors for stan­dard and highly sophisticated building concepts. One more thing, GU door clo­sers don't just work safely and reli­ably, are also nice to look at!Door closer
