Our History

From two craft businesses to a global technology company

Our story has promised excitement from the outset. The master turner Georg Friedrich Vöster, the mechanic Max Wessinger and the businessman Friedrich Carl Bauer first founded their own companies in different locations – until joining forces and laying the foundation stone for GEZE. A ground-breaking decision and the beginning of a long success story: because today – 160 years later – we are a globally active family business whose innovative solutions make buildings more comfortable.

What we stand for

GEZE Principles

We are proud of the history and achievements of our company and its employees. Our success and our growth are based on principles that we trust in, but which we also continually question – and further develop.

We support and connect all those involved in the building lifecycle – with one goal in mind: to develop comfortable residential and working spaces.

We always discuss our products with our customers to reach innovative and efficient solutions.

On the basis of the demand for our products we become an increasingly global and international company which is reachable locally by customers.

GEZE - Top Employer 2020

GEZE - Top Employer 2020

As a family business that looks back on almost 160 years of history, we attach particular importance to long-term relationships. Consequentially, aspects such as internal training and further education are very close to our hearts.

We are a learning organism and make use our own development potential first. We aim to fill specialist and management positions internally whenever possible.

As a family business, we therefore remain independent and flexible enough to identify and meet the changing needs of our customers.

To ensure we can supply state-of-the-art products and services to our international customers as quickly as possible, we manufacture at various locations – including China, Serbia and Türkiye as well as Germany.

But we always adhere to the same high quality standards worldwide. At the same time, we have a clear commitment to Germany, which will continue to be our most important production location in the future.

We offer our customers expert advice across every industry, and believe it’s hugely important to provide objective advice as our customers’ equals.

Whether in the healthcare or education sector, our experts understand the specific demands and can provide our customers with advice as well as practical support.

This ensures we can offer our customers optimal advice, and handle projects efficiently and in a goal-oriented way. Our excellent internal networking and worldwide locations ensure we can deliver this same service around the world.

We accompany our customers throughout the entire product life cycle. Right from the first planning discussion, we provide our customers with comprehensive advice – and listen carefully to what they have to say. We offer objective advice, and deliver door, window and safety technology from a single source. We can tailor our solutions to the demands and needs specified.

We take over the assembly of the products - if needed, we can also take over specialist planning. For example for barrier-free solutions. In addition, we provide comprehensive after-sales services, training and rapid assistance.

We can also carry out regular maintenance or statutory annual inspections for you. And here too, we are happy to support third-party products.

What sets us apart

GEZE quality

We set ourselves the expectation of continually optimising the quality of our products, and so naturally meet the quality management demands of DIN ISO 9001.

What’s important to us

We focus on sustainability

Sustainability is a focus area of the future and is one of our corporate guiding principles. Sustainability characterize our day-to-day activities in all areas – both with regard to our production processes and our products. This awareness is also reflected in our many years of membership of the DGNB (German Sustainable Building Council).

At GEZE, we have understood that buildings make an important contribution to sustainably reducing energy consumption and therefore CO2 emissions. That’s why smart and energy-saving solutions are more than ever the focus for our customers and us.

Sandra Alber, Chief Officer Legal & Finance at GEZE
  • Greenhouse gas neutrality by 2045 at the latest
  • Significant reduction of our greenhouse gas emissions by 2030
  • Focus on honest and long-term reduction of our greenhouse gas emissions 
  • Continuous expansion of ISO14001 and ISO45001 certified production sites
  • Continuously improving our products in terms of sustainability and the processing of sustainable materials
  • Utilizing innovations to better and more sustainably developmen of our products
  • Further development and establishment of a product cycle of our products and their sustainability from development to recycling
  • Expanding the criteria for sustainability in our supplier audits and thus the supply chain for which we are responsible

GEZE has stood for longevity from its very beginnings. As a family business, our focus is on generating sustainable returns rather than maximising profits in the short-term which is why all our internal production processes are committed to the concept of sustainability.

  • Research and development: ecologically efficient processes and concepts in research and development
  • Procurement and purchasing: consistent adherence to ecological principles in procurement and purchasing
  • Manufacturing and logistics: energy efficiency, preservation of resources and environmental friendliness are the principles in production and logistics
  • Recycling / disposal: minimisation of waste and achievement of the highest possible recovery rate in accordance with the ‘avoid-reuse-disposal’ strategy in the recycling / disposal sector.
  • Facility management: reduction of energy consumption and minimal environmental impact as a goal of facility management
  • Quality management system: certified according to DIN EN ISO 9001: GEZE GmbH (PDF | 310 KB), GEZE Service GmbH (PDF | 266 KB)
  • Energy management system: certified according to DIN EN ISO 50001 (PDF | 272 KB)
  • Environment management system: certified according to DIN EN ISO 14001 (PDF | 272 KB)
  • GEZE Service: sustainable innovative service concepts at GEZE Service
  • GEZE employees: committed implementation of the sustainability concept by GEZE employees
  • Company restaurant: catering company with organic certificate

The sustainability of our products is already reflected in their longevity. Due to the large proportion of metallic raw materials, the products are ideal for recycling - and are therefore particularly environmentally friendly. They also make a valuable contribution to energy-saving construction. For example, automatic door systems reduce the loss of hot or cold air through the door opening and eliminate the need for energy-consuming air conditioning systems.

Many of our products meet the sustainability criteria of the most important international Green Building assessment systems (German Sustainable Building Council [DGNB] and LEED criteria). We voluntarily make this information transparent via environmental product declarations (EPDs) for our products. For example, our TS 4000 and 5000 door closer systems, the ECdrive and Powerturn door drives as well as products such as the OL 90 N fanlight opener and our TSA 325 NT revolving door system meet stringent demands.

Our products can be found in the DGNB Navigator and online databases, along with the respective certificates. The certificates certify the number of points with which a GEZE product can contribute to the successful DGNB or LEED certification of a building, so supporting our customers in the successful Green Building certification process.

More about Green Building

GEZE is an active member of the DGNB.

GEZE is an active member of the DGNB.

As an active member of the Institut für Bauen und Umwelt e.V. (Institute for Building and Environment -IBU) and of the German Sustainable Building Council (DGNB), we have always supported sustainable building. As a company that has enshrined sustainable action as a corporate guideline, and whose products make an active contribution to energy-efficient construction with its products, membership of the DGNB goes without saying.

The German Sustainable Building Council understands sustainability as the obligation of society as a whole to assume responsibility for current problems such as climate change and resource scarcity. Sustainable building can make a key contribution to this. According to the Federal Environment Ministry, around one third of resource consumption in Germany is caused by buildings.
