About Roller Shutter
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
How does electrically operated roller shutter opener work
The weight of the roller shutter is supported by an axial concealed inside a cell horizontally above the entrance.
Microprocessor inside the control box received encrypted signal from the remote control, amongst other operation such as auto reversal upon obstruction and recognizing up to 16 remote control, opens or closes the door electrically with a motor.
The gate opener only needs to overcome inertia and friction to move the gate. Gate can go up to 6 meter in length and 100 Kg in weight. Material can be stainless steel, wrought iron, brass, Aluminum or glass.

Why We Do Not Recommend Roller Shutter For Garage Door
Modern over head garage doors have counter-balance spring and guiding tracks so that the opener only needs to overcome friction in order to open or close the door. Also, pulling the door along the center means better balance and stability.
In contrary, rolling shutter has motor operating on one side only, causing instability and noise. In general, roller shutter garage doors are slower, noisy and more expensive. Because of these reasons, new houses built in the west today do not use roller shutter for garage door. However, we have installed roller shutter on drive-way where there is no roof and not enough room for slide/swing gates.
