Abstract: A low-profile hinge for hingedly joining adjacent door sections of a sectional door. The low profile for the low-profile hinge is attained by using a relatively small diameter hinge pin fabricated from spring steel. The greater strength characteristic of spring steel compensates for the smaller diameter of the spring steel hinge pin to provide a hinge that has a lower profile while maintaining the necessary mechanical strength at a level equal to or greater than a conventional hinge. The spring steel hinge pin is fabricated to be incrementally shorter than the pin tube and the ends of the pin tube are crimped to retain the spring steel hinge pin in the pin tube.
