The company

Our philosophy

Innovative, yet down-to-earth. Open-minded, yet regionally rooted. Extremely versatile and steady at the same time – this is aluplast. Despite its international success, aluplast still is a family-run business. The company, which now in its second generation, is characterised by flat hierarchies and short decision-making processes.

Company founder Manfred J. Seitz and his sons Dirk Seitz and Patrick Seitz managed to transform aluplast into one of the most successful companies in its industry in just a few years. Four key factors played a major role in its success:

Our formula for success.


Constant product development and innovation are important to the success of both the aluplast group and its cooperation partners. We analyse current market requirements to create new products that satisfy the demand and meet our customers’ highest expectations. So it is no surprise to hear that our innovative power has been recognised, with aluplast being named one of the TOP100 most innovative SMEs in Germany.


Our customers and partners are at the heart of everything we do. The company headquarters also maintains close partnership and cooperation with its many different production plants and sales offices all over the world. This enables it to make the most of synergies.


Although aluplast has gone on to become a key global player, it has managed to retain the positive attributes that are often attributed to SMEs. Flexibility remains one of our greatest strengths. Short communication channels and lean structures allow us to respond quickly to customer demands and market requirements.


“Compatibility” is the secret ingredient in aluplast's recipe for success. But what does it actually mean? It means that all product ranges can be mixed and matched, making life a lot easier for window fabricators. The company's owners, the Seitz family, have cultivated this philosophy right from the outset, making sure that each new product lives up to this vision.
