Roll up garage doors

A roll up garage door is generally referred to a sheet or steel door that rolls up on opening. The distinct feature of this door is their ability to coil up just above the opening without occupying too much space. They are very different from sectional doors and function without a horizontal track system, and as they require considerable coil-up area, they cannot be installed in places with low ceilings. Here we will discuss the uses of different roll up door types, so you can ascertain what suits your need best –

• Rolling steel garage doors

A standard rolling steel door is built using metal slats and each slat is 22 gauges thick. These doors can be opened using any automatic openers and can function on a reduced drive chain hoist. The torsion springs are enclosed in a steel tube and as these doors are heavy, any type of broken spring repair should only be done by professionals. These doors can be insulated and are available in a wide range of finishes.

• Rolling sheet doors

The difference between a sheet and steel door is the corrugated steel curtain on the sheet door. These type of doors are relatively light and can be opened or closed manually or using a jackshaft opener. As they are less expensive these doors are usually found in small warehouses and sheds in the backyard, and it is easier to find replacement parts for them.

Rolling fire doors are the third type and these sheet doors carry a fire rating. They cannot function like a regular door and can be used only in case of a fire emergency. They usually have a fusible link that is attached between the cables. If there is fire, then the links melts and the door drops to close off a particular area. These fire doors are very expensive owing to their safety features.
