  "abstract": "A dual-strut channel includes a web having a first end and an opposing second end, the first end including a first series of spaced-apart, alternating projections and notches to form a first tooth-like edge, and the opposing second end including a second series of spaced-apart, alternating projections and notches to form a second tooth-like edge. A first flange and an opposing second flange each have a plurality of spaced-apart and aligned apertures which respectively receive the first and second series of spaced-apart, alternating projections extending from the respective first and opposing second ends of the central plate to form an H-shaped dual-strut channel. Exposed upper portions of the first and second series of spaced-apart, alternating projections of the first tooth-like edge are pressed until the first and second series of spaced-apart, alternating projections are flattened and press-fitted within the corresponding ones of the first plurality of spaced-apart and aligned apertures.",
