In the past the biggest concern with operating an overhead garage door was the potential risks associated with the springs used for balancing the door weight. Pre mid 1960s garage door installations typically relied upon a pair of stretched (tensioned) springs to assist the operation of the garage door pivoting hinges. These springs became loaded (tensioned) as the door was moved into the closed position. Unloading (releasing) of the stored spring energy occurred as the door was opened to the horizontal overhead position. One of the most dangerous aspects of these spring systems was that after a period of time often without any maintenance or inspection the points of attachment of these springs would rust or become weak.
This weakening of the springs or points of attachment would often lead to an inadvertent explosive failure flinging the broken spring components across the garage embedding the spring or steel components into the garage walls cars or other items in the path of travel. Unfortunately sometimes people were in the path of travel of these explosive occurrences. As these springs failed as an attempted safeguard some manufacturers devised a "caging" system for the springs. These cages were retrofitted onto the stretched springs in an attempt to capture the parts that would release if a failure occurred. While these caging devices were helpful they were not completely effective. Some of these spring devices are still in use today. Whenever this condition exists or the quality of garage components are questionable a qualified professional service technician should be consulted.
If you are looking for a more conventional garage door for your home Mission Garage Doors has a full line of metal doors to meet your construction needs. Their steel carriage garage doors are embossed to give the look of a real wooden garage door without all the maintenance that an all wood door will require. In addition you can select a wood panel exterior that will provide desired weather natural wood that is currently in demand.
In contrast to an overhead type of garage door be it sectional or single panel roll up doors have a totally different type of operating system. When these doors are used they can be concealed in an overhead or under mounted trough. These doors operate similarly to a roll top desk door except for how they are stored when not in the closed position. They normally coil as they are retracted and require significant gear trains to reduce the effort required to move these doors up and down into position. Often the forces needed to move these roll up doors require a reduction type of transmission that allows a very heavy door to be operated effortlessly.
