Product development.

Solution-oriented. Detail-loving. Design-driven.

What drives us is the ambition to find the perfect solution. To achieve this, HARTAL employs experts with great technical understanding and a love of detail. Our industrial designers work hand in hand with technicians and designers to provide perfect functionality. Our professional product designers, who have accompanied us for years and continue to inspire us over and over again, are outstanding at combining design with function. We cooperate with local technical colleges and independent institutes. This guarantees the use of state-of-the-art materials and manufacturing methods. The projects are realized using the latest 3D software (SolidWork) and visualized with 3D printing machines.

A finished HARTAL door represents the fusion of many details and a symbiosis of innovation, technical know-how, an understanding of user benefits and, last but not least, the experience of many decades. We love the challenge of finding solutions that are taken for granted at the end of the day.

We also receive awards for our work. For example the Red Dot Award 2020 for the “HARTAL concealed contact”. A small, very innovative product that virtually eliminates the possibility of cable breakage when the door is permanently opened and closed.
