Single and double-skinned steel doors

Secure guidance of the door in safety tracks.
Adjustable, patented track rollers, sturdy roller holders and safety tracks ensure that there is no danger of the door “derailing”. The door sections are safely parked under the ceiling.
 

Tension spring technology featuring a spring-in-spring system
Sectional doors with double tension spring and double wire cables per side safeguard the door  leaf against crashing to the floor. Thanks to the patented spring-in-spring system, a broken spring cannot be catapulted into the air and cause injury.

Double-skinned doors have additional high-grade intermediate seals between the individual door sections.
