International
We are crossing borders. Not only when it comes to the question of whether security technology is feasible, but also in the geographical sense. An international focus has been part of our company concept right from the start. Today we have representing branches in Spain, the Netherlands, Italy, Portugal, Greece, Dubai and India.
Our products are exported to more than 35 countries and our export business share is about 30 to 40 percent – with a rising tendency. Attending many international exhibitions at home and abroad complements our global activities and is also a facet of practical customer proximity.

The beautiful game
"We are East Westphalia" - with this slogan from Arminia Bielefeld we can fully identify as company located in Bielefeld. Loyalty and solidarity are East-Westphalian virtues that both – our club as well as our customers – can count on.
Naturally we support "our" club – even if we didn't manage to stay in the 1st division this time.
Good luck in the 2022/2023 season in the 2nd Bundesliga!
