The KOS company manufactures sliding and revolving doors for special applications. Depending on the requirement, these doors can be hermetically sealing, automatic or manually operating and can be produced in different optical variations. The heart of the product range are the sliding doors, which are based on the proven principle of the lowering door leaf in order to achieve a hermetically sealed closure in combination with surrounding rubber seals.

When the company was founded in the year 1991, it provided installation, maintenance and repairs of special doors for the German market. In the course of the years, we were able to provide our services in the whole of Europe and beyond.

In the course of the globalisation of the world, we also passed into setting up the development and manufacturing of our own innovative door system in addition to the first-class service in the field of installation.

Since 2001, special doors are manufactured in our own production facilities for all of Germany and abroad. Due to modern production processes as well as the execution of all manufacturing processes in our own factory, we can guarantee high quality and the shortest delivery times. Our success is reflected in our extensive reference list.
