GU door hinges for project, residential, and side entrance doors
In public buildings, doors are constantly in motion, so solutions for doors with high loads must be reconciled with requirements for security and design. GU door hinges combine universal applicability with an elegant appearance and meet the highest technical standards. Safety always comes first: our door hinges impress with tested burglary resistance up to resistance class RC3 in accordance with EN 1627-1630, thus ensuring reliable protection, even for emergency exit and escape route doors.
Function and construction
Door hinges form the crucial link between door and frame and enable the smooth rotational movement of the door leaf. They basically consist of three components: the lower hinge part, which is fixed to the frame or casing, the upper hinge part, which is attached to the door leaf, and the pin, which acts as the pivot and ensures the connection of the two parts. They are available in two- and three-part versions.
GU door hinges for PVC elements
For PVC elements, we offer both butt hinges and robust screw-on hinges. Butt hinges impress with their elegant, slim design: when the door is closed, only the pivot rollers are visible, giving them a particularly modern and discreet appearance. For heavy doors, screw-on hinges are also available, providing high load-bearing capacity for lasting security. In this way, our door hinges for PVC elements ensure both aesthetics and reliable functionality.
GU door hinges for wooden elements
For wooden elements, we offer a wide range of door hinges, including concealed hinges as well as mortise and drill-in hinges. Concealed hinges are particularly in demand, as they enable a modern, linear door design that does not interrupt the clear lines of the door. Versions are available for both rebated and flush doors. Our adjustable mortise hinges are available either with an elegant stainless steel hinge roller or as a version with clip-on sleeves for a wide variety of colors. The range is complemented by drill-in hinges, which allow quick and easy installation, thus perfectly rounding off the product portfolio for wooden doors.
GU door hinges for metal elements
GU screw-on hinges combine a delicate appearance with high, long-lasting load capacity and, thanks to their universal applicability, are ideal for metal doors in commercial and residential construction. In addition, they offer increased burglary resistance and are SKG-certified with up to 3 stars, thus meeting the highest security requirements.
Project hinges for doors in emergency and escape routes
Every second counts in escape and rescue routes – and the quality of the components used can be a matter of life and death. Gretsch-Unitas therefore offers you a comprehensive range of CE-certified door hinges according to EN 1935, which are approved for use on emergency exit and escape route doors. With the GU license for PVC doors, the time-consuming individual test of the "release capability" by a notified body is no longer required – for greater planning reliability and efficiency.
