Considered technology

Because of its particular use every garage should be a safe and functional place. Each one should have a gate, that not only protects the car but also guards the access to the house.
Sierant company manufactures rolled gates – a universal product that can be installed both in newly built or already existing buildings.
Because rolled gate is lifted upwards it is particularly good solution where the driveway is short or leads directly to the street. It enhances the safety of the driver, because lifted gate does not limit the visibility and saves space.

PA77 – is a tight profile filled with polyurethane foam, a great heat insulator, resistant to mechanical damages, gate made of this profile is by default equipped with mechanism that protects it from unauthorised lifting.
PER 77 - as an aluminium profile with glazed apertures that makes it possible to see through the gate, PER 77 profile without the glazing can be used as a grating (in shops, industrial halls and garages).
PEW 77 – is a profile with ventilation apertures which facilitate ventilation of the building.

Due to the large dimensions, it is advised to equip the rolled gate in electric motor. Electromagnetic break of the motor (along with blocking hangers) effectively prevents from levering the gate. If any object is placed in the ray of the photocell the gate stops immediately. Power malfunction is not a problem either. On electricity malfunction the gate can be opened or closed with emergency manual operation (NHK) the engines can be equipped with.
