Hans Seisenbacher founds a locksmith's shop in Ybbsitz. Initially, the focus is on manufacturing stone breakers.

With its own subsidiary in Ybbsitz, CNC manufacturing is further expanded. This marks the beginning of the era of special machine construction.

A new production hall for mechanical assembly and final assembly is opened in Waidhofen an der Ybbs.

With the establishment of the Interior division, the company lays the foundation for future success in the field of rail mobility.

A new 20,000 sqm production and administration building is built at the Ybbsitz site, replacing the previous facility.

Seisenbacher's transformation into a partner for the interior design of rail vehicles is well underway.

Seisenbacher is acquired by the private equity firm Aeiphoria Capital, founded by Dr. Thomas Maidorfer, Felix Porsche, and Martin Wodak. The intention is to support Seisenbacher in becoming an innovative and forward-thinking provider of holistic solutions for the rail vehicle industry.

Dr. Alexander Frech joins Seisenbacher's leadership team. With new investors and the appointment of a new CEO, the company undergoes effective restructuring of its operations, experiencing significant success.

Our recent investments, including the new warehouse and photovoltaic system, demonstrate our strong commitment to green energy and sustainability. Transitioning to 100% sustainable electricity supply marks a crucial step towards carbon neutrality. Additionally, since 2023, we have introduced a monthly communal breakfast to enhance transparency and keep everyone informed about current developments.

GB Metals becomes part of the Seisenbacher family, bolstering our manufacturing expertise with its own production facility specializing in sheet metal processing.
