In the beginning there was the single-line fanlight opener MARS®. The HAUTAU brand grew out of this hardware, which turned 110 in April. In 1910 company founder Wilhelm Hautau started his inventions in a small workshop. Today you will find our products all over the world and over 300 employees in Helpsen, Lower Saxony, who are motivated to think along and think outside the box. At HAUTAU traditional values meet the latest technologies and a modern and future-oriented industrial company.
