The Door Panel

The door panel is made by robust steel reinforced stretch-frame holding pressure cast Polyurethane foam between outer coverings.

The pressure cast Polyurethane foam is completely Freon free making the door the most sturdy and resilient in its class. *(Figure: Of 52Kg density / m3). The reinforced stretch-frame is either 3mm, 4mm or 9mm thick steel with anchor profiles to reinforce locks, hinges, mountings and fittings for incomparable durability.

Top and Bottom Tracks

The door panels are supported by double wheel top rollers which run in a heavy-duty top track and supported by cantilever brackets. For larger openings a twin or triple track system is supplied.
A bottom track and guides are also supplied, which allows the doors to stay in the vertical position and run smoothly even in high winds.

All electric operated Q doors are automatic locking.

Manual operation

Q Door is operated and locked as standard on the inside using a padlock on an external cremone bolt. As an extra the cremone bolt can be fitted with a cylinder lock (excl. cyl.)

Sealing System

It is important that the door is equipped with a sealing system that withstands ageing.


Windows can be placed in variable combinations and sizes in the door panel as an extra option. The standard windows have aluminium frames, with the option of powder coating . All windows are constructed with an open thermal bridge between the inner and outer frame and toughened insulated double glazed glass as standard for insulation. The glass can be hardened, laminated or coated with sunscreen.

Safety Factor

Built within the sealing system at the front edge of the door and, if necessary, also at the back edge, are safety edge sensors, that will send a response to the door control when an object obstructs the travel. The response will make the door to stop and reverse the direction of movement.

Sections and Movement Directions

We manufacture the sliding doors of one or more panels, which means that the width basically becomes unlimited. You can get a single-section sliding door with opening to the right or left. The Bi-Parting sliding door normally opens in two directions. In special cases, we can produce your door with a double or triple carrier rail, so that you can open sections in one direction.
