The history of the garage door could date back to 450 BC when chariots were stored in gatehouses, but in the United States, they arose around the start of the 20th century. As early as 1902, American manufacturers—including Cornell Iron Works—published catalogs featuring a "float over door." Evidence of an upward-lifting garage door can be found in a catalog in 1906.
A typical version of an overhead garage door used in the past would have been built as a one-piece panel. The panel was mounted on each side with unequal parallelogram style hinge lifting mechanism. Newer versions of overhead garage doors are now generally built from several panels hinged together that roll along a system of tracks guided by rollers. The weight of the door may be 400 lb (180 kg) or more, but is balanced by either a torsion spring system or a pair of extension springs. A remote controlled motorized mechanism for opening garage doors adds convenience, safety, and security.
