Our company philosophy is characterized by high quality standards. We feel a great personal esteem towards employees, customers. partners and suppliers. Always with the aim of offering individual and customized solutions for high-speed doors.

Our industrial doors are much more than fast rolling doors!

All doors are manufactured without exception at our production site in Melle-Gesmold (Osnabrück district). Especially now, in times of disrupted global supply chains, this is an important criterion for us and our customers.
From the frame to the bracket to the drive shaft, only high-strength materials made of steel or stainless steel are used.

An important unique selling point is the light grid (protection class IP67) we install. This component is low-maintenance, safe and easy to install. In conjunction with the absolute encoder, the electronics monitor the closing level of the door leaf up to a height of 2500 mm.
The control system knows at all times the position of the closing edge of the door during door travel.
Persons, vehicles or objects are thus reliably detected. This prevents collisions or personal injury.

Frequency Inverter Control and Anti-Crash System

Every door from our production is equipped with a frequency converter control. The electronics relieve the door mechanics by gentle starting and braking of the door curtain. This extends the service life of the mechanical components and thus also of the door.
Despite the high mechanical load, this also ensures low-wear, quiet door operation. Short opening and closing times reduce energy loss and prevent drafts. This enables undisturbed operation.

The combination of anti-crash system and flexible end profiles prevents damage to people, machines and the high-speed door. After a crash, the high-speed door automatically reinserts itself into the guide rails of the door. As a rule, no service intervention is required.
Downtimes are thus reduced to a minimum.
