Berk Partners

Amsterdam, 22 MAY 2023 – Investment fund Berk Partners on 17 May 2023 acquired a substantial stake in Gendringen-based company Rolflex Nederland B.V. Rolflex is the inventor of the compact, folding commercial door. This unique industrial door without ceiling tracks fits everywhere – even where other sectional doors do not – is low-maintenance, high-quality, durable and aesthetically very representative. The unique industrial door is developed and produced entirely in the Netherlands. Worldwide installation and maintenance are facilitated with an extensive dealer network.

Rolflex supplies the Compact door in various colours and finishes. The door can be further extended with (semi)transparent panels, a wicket door, remote control and more


Rolflex is the manufacturer and supplier of specialist, high-end commercial doors. Development and production is done in-house. Rolflex is fully dedicated to the Compact door. This is a folding door based on multiple customisable and customisable panels, which fold upwards when the door is opened instead of being slid or rolled over rails on the ceiling. The main advantage of this is that ceiling space is saved and the service door can be fitted better into existing situations. Folding also allows the service door to be fitted with, among other things, a wicket door and the option of installing the door on the outside of the room. Rolflex is the inventor of this type of folding door and has been the technological leader in this field for more than 25 years.

Sales of Compact doors outside the Netherlands are largely through an extensive international network of over 450 dealers. These dealers install and maintain the Compact door at end customers. Within the Netherlands, installation and maintenance of doors is carried out by Rolflex itself.


The transaction is a management buy-out/ pre-exit. On 17 May 2023, Berk Partners Growth Fund and managing director Maarten Coerman joined as shareholders. Coerman, together with the existing management team, forms the driving force behind Rolflex. Together, they will focus on further expanding Rolflex in the coming years.

Coerman foresees interesting growth opportunities. “With Berk Partners’ involvement, we can further expand internationally, professionalise and Berk Partners’ networks will also become available to Rolflex,” Coerman said.

“The collaboration with Berk Partners is a conscious choice,” said Frank Govaert (partner at Berk Partners). “This partnership offers Rolflex the opportunity to grow further through increased focus on innovation and commerce, where Berk Partners will support to further shape growth. Berk Partners has gained a lot of experience with growing companies in the past.

In this respect, Rolflex fits well with our investment policy. Rolflex operates in an attractive niche market and occupies a leading position there with a distinctive product. The incumbent management also has a very good track record when it comes to international growth.”
