Garage doors differ in many aspects; especially, they differ in terms of the operating mechanism used to open and close the door. A roller door gets its name from the way the curtains are from galvanized material, lightly curling up or down the tube placed above the garage entrance.
Roller garage doors are different from other mechanisms because they are lightweight, easy to care for, and easy to operate. Most roll up garage doors are usually made of galvanized plastic coated steel sheets or double-skinned aluminum slats.
Compared to sectional doors, for example, roller doors do not have wide panels, but instead, use a hinged design to facilitate efficient upward or downward rolling movements for roller doors.

Other materials include tracks that rise as high as either side of the garage entrance, a weather-resistant rubber seal that closes the gap between the door and space around the opening, and a tubular drum mounted above the entrance where the curtain is stored when the door is being used.
Roller garage doors are very beneficial for those who have limited and narrow garage lanes, as well as those who have rather small garages that can only fit one car. This is because the mechanism of operation of the roller door does not require a large space outside or inside the garage.
In addition, because the roller door is made of durable material, the door is guaranteed to be stronger against impact and not subject to dents and arches. This type of door is also popular because it is relatively easier to maintain compared to other types that use a balancing mechanism.
