Tradition meets modernity – an established family business introduces itself
The company GL LUDEMANN ARMATUREN GmbH was founded in 1962 by Geneviève and Helmut Ludemann.
Eric Ludemann, son of the founding couple, has been part of the company since day one.
With his experience and his professional and committed approach, he has played a significant role in the development of the company – from its origins as a small family business to one of the market leaders in the industrial fittings industry. With the establishment of our subsidiaries in the Netherlands and France in 1989, he further expanded this position.
Sharing his enthusiasm for the products, as the third generation, his daughter Martina Ludemann-Sauerwald joined the management team in May 2008.
She started by supporting her father in the further development of the sales and marketing before becoming managing director of the company in 2018.
