A sectional door, which may be an overhead door such as a residential garage door, including hingedly connected door panels each being formed from a plurality of subpanels. The subpanels forming each door panel are disposed end-to-end to form the entire length of the door panel. Rigid connection between adjacent subpanels of the same door panel is made by at least one and preferably two connecting bars extending within channels of adjacent subpanels in a lengthwise direction. The connecting bars are each formed of a length substantially less than the overall length of the door panel but slightly longer than the length of an individual subpanel. All components of the door may be stored and transported in relatively small packages or cartons, yet may be assembled into a structurally rigid, wind resistant sectional door. |
