Abstract
A sectional garage door is formed of rectangular door sections which include hollow extruded plastic rail members interconnected by hollow extruded plastic end and intermediate stile members to form a door section. The rail members and stile members may be fitted with internal tubular or channel shaped metal reinforcing members to minimize deflection of the door sections during use. The door sections may each include an externally fitted strut which is secured to a longitudinal side edge of a section and is connected directly to a reinforcing member disposed within one of the rail members without being forcibly connected to the rail member itself to allow for differential thermal expansion between the rail member and the reinforcing members. Rectangular panel inserts may be removably supported on each door section by removable retainer members and may include insulated panel inserts which may be added to the door sections before or after installation.
