50 years of ALTEX

That is much more than just a number — it is the story of many people who work day in and day out with passion and expertise toward a common goal. For my brother and me, it is a special honor to continue the family tradition and lead the company into the future. A lot has changed over the past decades: markets, technologies, expectations, and challenges. Yet one thing has remained the same – our ambition to always give our very best. For our customers, for our company, and for one another. We know that ALTEX’s success is the result of collective strength. Only with a dedicated team can a company survive and grow over so many years.
For this, we would like to express our heartfelt thanks to all our employees, partners, and colleagues who have made ALTEX what it is today. We look back with pride on 50 years of company history – and forward with confidence to all that lies ahead.

At the Gronau site, decades of experience meet state-of-the-art technology. With currently more than 100 dedicated employees, we produce around 10,000 tons of needle fleece each year. This corresponds to an area of more than 4,000 football fields. Our strengths lie in cutting-edge production facilities, an optimally coordinated raw material supply and in our team. With decades of experience, technical expertise, and a spirit of innovation, we set new standards in quality and efficiency every day.
This makes ALTEX a modern, reliable partner for the automotive industry, the geotextile sector, home, eco-tech, and many other industrial applications. More than half of our products find their way to markets around the world – a strong sign of quality, innovative power and trust “Made in Gronau”.
