Enthusiasm for perfect technology, outstanding design and excellent service have made Dr. Hahn one of the most innovative companies in the development and production of hinges for metal and PVC profile doors. Dr. Hahn offers precisely the right solution for any situation. Screw-on hinges, butt hinges, clamp hinges and concealed hinges meet all requirements due to maximum quality attributes.
The employees of a company are the source of success. They determine how well a company really operates. That's why we give our employees the necessary leeway for creatively addressing customer wishes and market requirements. After all, personal satisfaction and the opportunity to identify oneself with tasks and goals make the difference that makes a product really better than others.
A well thought-out strategy for assuring quality is necessary to ensure that outstanding ideas are translated into winning products. While strategy starts out with development and serves as a basis for procurement and production, it does not end with the sale of products. Thus, it stands to reason that we use high-quality materials and test according to the most stringent international standards (RAL, SKG, Ü label, CE mark) and that we are certified in accordance with DIN EN ISO 9001:2008 and DIN EN ISO 14001.
Decades of experience, closeness to the market and constant dialogue with customers enable us to identify trends and developments in constructing doors early on and to respond quickly to new requirements. By regularly investing in cutting edge production technology, we are capable of manufacturing custom-tailored solutions as well. Since most of our products are manufactured inhouse, we are able to offer prices that are consistent with the market, even with smaller production lots.
Every day we face new challenges, and we are constantly looking for new solutions and improvements. Nowadays, almost every installation situation involving metal and PVC doors can be solved using a Dr. Hahn hinge. On top of that, we consciously focus on simplifying handling, i.e. installation and adjustment, to save fitters valuable time and resources and to ensure a smooth process through to final installation of the door.
With the rapid pace of life today and communication channels changing and becoming shorter, it is necessary to react quickly and provide the best possible support. Dr. Hahn has put together for its customers a service package that is hard to match. Competent technical advisers resolve the technical situation and requirements at the outset. All our products come with high-quality documentation so that it is always readily available where it is really needed. Moreover, documentation can be downloaded on demand from the Internet.
Contemporary architecture and modern design call for a keen sense of forms, colour, finishes and functionality. Only after achieving perfect harmony with respect to the individual elements does an entire object become a visual masterpiece. Whether the task involves making a statement or designing a conservative element by concentrating on what's essential, Dr. Hahn fulfils the wish for something special. That is why the Hahn VL-hinge was awarded the renowned industrial design prize "red dot".
Although we have achieved a lot, we still do not allow ourselves to rest. We think ahead and constantly search for innovative solutions which will definitely meet the demands placed on building fittings today and tomorrow. Our success is proof that this strategy is right. But this success also comes with obligations, for instance to protect especially the environment. Besides high productivity, the most important criterion for new investment decisions is environmental protection.
Hahn hinges are subjected to the most diverse strains on a daily basis. Over the years, we have gathered a lot of experience and recognition due to the fact that our hinges are used in many locations throughout the world, as can be seen in our list of references. Hahn hinges can frequently be found in commercial buildings and office premises as well as in private homes, always opening doors ...with hahnfunction.
Dr. Walter Hahn, Company founder

Dr. Walter Hahn founded the company in 1961. Focus was initially placed on the thermoplastic moulding of plastics. Door hinges were required for presenting these products at a fair. The positive feedback was mainly responsible for the production of door hinges since that time.
Dr. Walter Hahn founded our company in 1961. We were initially concerned with the moulding of thermoplastic parts.
We originally produced PVC articles such as canopies and door fittings, followed by tube door closers. For presenting these products at a fair we required door hinges that then proved highly popular with the public. The positive feedback was mainly responsible for the production of door hinges since that time.
Aluminium profiles became increasingly popular as time progressed, and PVC profiles a short time later. The first Hahn hinge for PVC doors was launched in the market in 1984.
The demand for improved quality and design increased over the years. The first butt hinges and clamp hinges in 2001 set initial trends in hinge design. Today, butt hinges give doors a more sophisticated appearance throughout the world.
With the VL-Band ST and VL-Band AL concealed hinges we set a further milestone in terms of hinge design. Several international competitions have distinguished us for the design of Hahn concealed hinges.
We have filed patents for hundreds of inventions over the years. Among them are various hinge fastening solutions. We launched the step screw in 2001, followed by the screw anchor in 2005.
Since the year 2007, the anchor screw has made the fastening of our hinges easier, at first for Türband 4, then later also for the Series 60 AT and Türband 4 AT. The door builder now saves around half of the usually required working time with the Hahn anchor screw.
Turning old into new – the Türband 3 has been replaced by the new Türband 4. In addition to the hinge’s universal use, the improved follow-up model can also be fastened using the newly developed anchor screw, thus offering maximum comfort.
In 2009 the next step into the future was taken because space at Mönchengladbach was no longer sufficient. Just eight months of construction time was needed to create a modern production, storage and management building in Erkelenz on a plot of land of 53,000 m2. The architect designed the management building as an oversized door hinge, making it the largest door hinge in the world.
In 2010 the first concealed door hinge for PVC doors was launched in the market in the form of the VL-Band KT. The year saw a further innovation with the KT-FIX fastening solution. FIX in this regard indicates especially quick fastening and particularly firm attachment.
Dr. Hahn’s popular universal Series 60 AT hinge shines in new splendour. The modern design and improved technology are immediately evident. The new hinge series has been designed such that all mounting variations offered in our range can be implemented. Be it traditional installation with base plate fastening, modified with the screw anchor or with the completely new Hahn anchor screw. The Series 60 AT New offers a fitting solution for every door frame.
We developed a bearing bolt with anti-saw protection for our KT screw-on hinges to ensure increased protection against break-ins. This makes it impossible to saw through bearing bolts with a hacksaw.
Türband 4 AT is the flagship product in our door hinge range. We have now improved some important features in the hinge. In addition, details were incorporated into the design to make handling even more efficient in the workshop and on the building site. Another new feature in the series is the half measure zero, where the frame hinge blade has been reduced to the minimum space required. This new variation is used especially in situations, where there is only a small amount of space on the frame side.
Door hinges should still be able to work on angular fronts, recessed profile sections or high upstands. The Hahn KT-B 6R can also be used on a wide variety of profile sections. With this elegant door hinge, we are now able to handle almost any installation situation on a block profile section.
For use on high-quality aluminium doors. With the new Rollenband AT, we now offer a hinge system that can be adapted to all major door frame systems. Its barrel with a diameter of 20 mm meets the high design standards that building owners and architects have for making sure that hinges on their residential and commercial doors are as unobtrusive as possible.
Very delicate look – that is our motto here! The two series, the Hahn KT-RKN and Hahn KT-RKV, are each available in 2- and 3-piece versions. With a hinge diameter of only 18 mm, you can still support standard door weights with PVC profile sections. A new addition to the line is the silver anodised colouration (EV1).
Slim, stable and three-dimensionally adjustable. Dr. Hahn has introduced 2- and 3-piece door hinges for common PVC profile systems under the names Hahn KT-RV and Hahn KT-RN. In particular, the design with a slim hinge curl having a diameter of 22 mm looks both robust and elegant at the same time. This impression is additionally supported by the extended colour range in silver anodisation (EV1).
The technical advantages of the Hahn VL-Band AT include faster processing, greater convenience on the building site and easy adjustability. The new, concealed hinge design for doors made of flush-mounted aluminium profiles is completely concealed inside the profiles and meets the high design standards of building owners and architects.
