Open House
May, 4th, 10-17 Uhr

GLOTTERTAL. BEHA, a renowned German family business in the heart of Europe, is proudly celebrating its 50th anniversary. For half a century, BEHA has stood for innovation, quality and global market presence. With subsidiaries in Europe, the USA and Asia as well as a worldwide sales network, the Black Forest-based company has come a long way. 

To celebrate its 50th anniversary, Beha invited visitors to its premises in Glottertal for an open house on May 4th, 2024. 

After the official opening by the Beha family, represented by the 2nd generation managing directors Markus and Lars Beha, and words of welcome from Glottertal’ s mayor Karl Josef Herbstritt, there was plenty on offer for visitors and guests. 

For the children there was a colorful offer with face painting, self-welded bracelets made of transport profiles and many toys from the Freiburg Spielmobil. Free refreshments including drinks, barbecued sausages and coffee/cake were provided by the youth section of DJK Heuweiler.  

The main attraction, the guided company tours lasting just under an hour, was very popular. Here, visitors were guided in groups through the various areas, from the extrusion and fabrication of round and V-belts to HDT’s global measuring device division. 

“With around 70 employees and 9 trainees here at the site, it underlines how important the future is to us – not only for our company, but also for Germany as a business location. It was great to see how many young people were interested at the open house in the internships and the various technical and commercial apprenticeships we offer,” says Bernd Beha, second generation and HR manager at the site. 

With around 700 visitors and good weather, the open house was a complete success. “Such a great response makes me proud of what we have all built up together here at Beha over the last 50 years. Looking back on the last 50 years, I can only say – it was worth it. The next 50 years can come,” says Bernhard Beha, co-founder and Managing Director of the first generation. 

HDT – Hoover Dam Technology
Test and measurement instruments for electricians

The “UNITEST” test instrument division of Beha was founded in the early 1970s and expanded internationally very early on, with its own plants in Ireland and China. As a premium brand for the electrical wholesalers, it became known primarily in the D-A-CH region.

In the 1990s, a second division was established under the name “Ireland Meter Electronics” (IME), to supply the hardware stores’ own brands with OEM products. As a result of increasing international competition due to globalization, the “UNITEST” brand division was sold to the world market leader Fluke in 2003, in order to enable further growth and development for “UNITEST”.

The second business unit working as an OEM / ODM manufacturer of test instruments was gradually build first under “IME” and later under “HDT”. Today the OEM / ODM test instrument business is what the Beha companies operating under „HDT“ are doing quite sucessfully.

TPU profiles and conveyor belts for drive and conveyor technology

The „BEHAbelt“ division, which emerged from a research project and a general agency, was a profi t centre within the company in the early years. The company very quickly gained a reputation as a problem solver and innovator. Among other things, specially developed welding equipment, for which patents were successfully filed in the 1990s, contributed to this.

Following the sale of the „UNITEST“ brand business in 2003, the „BEHAbelt“ division was further expanded. In 2005, we developed into a fully integrated brand manufacturer by insourcing our own production.

Internationalisation followed in leaps and bounds, as did the expansion of the portfolio to include conveyor belts and other innovative welding technology products under the heading „smart conveying“.

Nuclear Research Centre in Karlsruhe

Company founder Christian Beha went to the Karlsruhe Nuclear Research Center after graduating as a technician.

There, in addition to his work in the nuclear power research department, he got a degree in mechanical engineering from the Darmstadt Open University.

It was there that the idea of founding a company arose, which he then realized after returning to his hometown Glottertal.

A logo is born – the birth of Bernie the seal

At the beginning of the 1970s, BEHAbelt profiles began to be sold through distribution. The need for clear product labeling soon arose. However, trade´s concerns about users ordering directly from Beha also had to be taken into account.

This is where the new home of our electronics manufacturing in Ireland came into play – Roundstone. Mistakenly translated by the English as “round stone”, the Gaelic name “Cloch na Rón” actually means “seal rock”. As those little animals are not only likeable but also stand for things like friendliness, openness and adaptability, it was quickly decided.

In 1981, the seal was added to the BEHAbelt logo and Bernie was born.
