Overview, Design & Properties

The Marc-R sliding double fire door comprises the following basic components: two door leafs, the truck rail running system, the stile, the labyrinth sealing components, and the optional man door.

The door leaf (60 or 100 mm for EI120 or EI30/EI60, respectively) comprises upright panels which can be 400 to 1200 mm wide, the top profile, the bottom profile, bracing hardware and cladding of galvanized sheet steel. 

Each door leaf panel features a modified, fire-resistant mineral wool core in class A1 with internal reinforcement formed by steel bars (a solution protected by European Patent no. W 02/079600A1).

The truck rail running system of the door comprises steel trucks, a steel truck rail and the double closing movement operated by a counterweight. Optionally, the doors can be operated with type VIC electric drive units. 

The standard colour selection includes RAL 7035, 9002 and 9010. 

The sliding double doors can be optionally provided with a man door. The standard man door version is provided with a lever tumbler lock, double-sided door handle hardware and spring-return hinges. The man door can also be provided with panic exit devices (with locks or levers), and a sliding rail door.


The Marc-R sliding double fire doors are intended for regulatory-compliant separation of fire zones inside and outside of buildings and across handling system flows.

This product is mainly intended for public buildings, shopping malls, industrial plants and warehouse buildings. It is a perfect wall closure solution whenever the installation clearance can be provided on both sides of the wall opening.

The sliding double doors can have optional man doors; if the parking space beneath the overhead door is limited, the door can have a telescopic leaf.

Operating principle

The basic door version has the leaf closed by gravity-assisted movement of the counterweight. The door can be held open with an e-mag holder wired to the on-site fire alarm control panel. In the event of a fire alarm, the control panel releases the e-mag holder and the door leafs close the passage between the fire zones. The door can be opened manually. The door can be optionally provided with an electrical drive unit which operates the door to open and close. The door can be delivered without a counterweight.
