About us

With two innovative own brands and a customer-oriented approach for manufacturers of doors and windows, we lead the way in “the entrance”.

The playing field between inside and outside fascinates us. On the one hand, they want to exclude harmful external influences such as noise nuisance, cold, heat, pollen, vermin, bacteria or unwanted visitors, etc. On the other hand, people seek contact with the outside world. This is very clearly visible in the architecture. From glass facades to outdoor rooms, improving both the indoor microclimate and the outdoor climate through green roofs, facades, roof gardens, etc. Lowering emissions and saving energy have become important themes. Modern man places high demands on his living environment. Good design and reducing the impact on the environment is no longer the wish of a few, but the requirement of many. How can door-line respond to this and secure its right to exist in the future?

“ We believe in local production for local markets.
If you want to continue manufacturing in Europe, you have to be at the forefront of development and have your own products. ”

As a producer of brushes (previously under the name GeZu and later as door-line), draft barriers, seals, letterboxes and doormats are commonplace. We believe in local production for local markets. If you want to continue manufacturing in Europe, you have to be at the forefront of development and have your own products. That is why we constantly research functionality on the border between inside and outside. We try to apply the things we learn as broadly as possible in a market-oriented approach as a sealing specialist. Everything we learn about innovation, design, packaging, logistics, etc., we put at the service of our customers. We produce, source and fulfill our agreements.

We produce a range of seals and plastic injection molded products in our factory in Nijkerk. Here we also have a flexible assembly and assembly department.
