Reinforcements for the horizontal lateral edges of a garage door panel, which have been reverse folded to a J-shaped section, provide a neat channel for nesting a reinforced bar, such as an extrusion. One such extrusion, being C-shaped in cross-section, provides space for the off-setting adjoining female member of the lateral edge. At the other longitudinal side, a rectangular channel or extrusion can be similarly nestled into the J-shaped cross-section. The vertical ends and the vertical reinforcing truss provided at various stations have a similar C-shaped recess, and an extruded channel positioned in the same recess will cause every single panel of the door to have a plurality of reinforcing frames at every location where intercepting members appear. Desirably, the reinforcing members are secured in place of cementaceous material to thereby avoid the unsightly appearance of a pop rivet or other fastener.
