A sectional upward acting door includes interconnected door panels which are formed with generally planar outer and inner wall parts and upper and lower edges which cooperate to provide a pinch resistant joint between door panels when they are pivoted relative to each other. Spaced apart snap together hinge assemblies and snap in place guide roller support brackets may be used to assemble the door by moving the panels into assembly with each other between the door guide tracks. The panel edge profiles are formed by a convex surface on an upper edge of one panel and a cooperating concave multiple planar segment surface on the lower edge of the adjacent panel. An elongated seal strip may be secured in a groove in the lower edge of one panel and engageable with the apex of the upper edge of the adjacent panel. The panels are formed with inclined wall parts spaced inwardly of the pinch resistant edge profiles for supporting the hinge assemblies within a recess so that the hinge assemblies do not protrude inwardly of the generally coplanar inner wall parts of the panels. The hinge assemblies include opposed hinge plates with separate or integrally formed hinge pins on one hinge plate and the other hinge plate is formed with opposed elastically deflectable retainer tabs which allow the hinge pin to be snapped into a bearing bore in the other hinge plate to facilitate connecting the door panels to each other.
