These doors can be chain driven either manually or can be automated using electric motors. Roll up doors require more frequent evaluation and servicing than a standard overhead garage door. The tracks that are mounted vertically on both sides of the garage opening need maintenance and cleaning more frequently and are often blocked by foreign obstructions or damaged by collision of some type. These roll up doors are often held open by some type of ratcheting action. Proper balancing of these doors is often more important than an overhead type of door as the weight of these type of doors is normally much greater than an overhead door.

With a torsion type of spring the energy is imparted or removed by rotating the spring clockwise or counter clockwise depending upon the direction of usage. With professional installation the complete loading of the torsion spring is controlled by the garage installer and is determined by the weight and size of the garage door that it is operating. When this type of torsion spring fails it remains attached and intact to the location on the horizontal control rod where it was mounted. I have not heard of or seen any torsion spring fly across a garage creating injury from failed components as with the stretched older style garage door springs. This is not to say that injuries have not occurred with the torsion style spring. The installation of this type of spring is generally safe when left to a trained garage door installation professional. Severe and serious injuries have occurred when untrained unqualified individuals have attempted to install or service this type of spring.
They are available as a prefabricated kit or built as a custom design to complement the dacor of any building. Commercial warehouse type installations often dictate higher security requirements. A good choice for this security type of door is the "roll-up" style that resembles a roll top desk type of door. This door can be manufactured with a variety of materials that can be as strong as the adjacent walls making forced entry through this opening very difficult. Other common commercial installations include light weight aluminum single or sectional panel doors. These doors function more for closing off an already secured area than for assuring point security.
