At least two stiffening ribs are integrally formed in the panel and extend longitudinally between the first and second end portions. The first side edge portion has a beveled configuration and is integrally connected to an elongated male connecting member. An elongated female connecting member is integrally connected to the second side edge portion and extends adjacent the interior surface to define a fold. The elongated male connecting member of one panel is cooperatively profiled to mate with the female connecting member of an adjacent panel. ## Claims ### Claim 1 A universal structural metallic panel system, comprising: at least one elongated panel having opposing substantially planar exterior and interior surfaces, a first end portion and an opposing second end portion, wherein the first and second end portions are differently configured, and a first tapered side edge portion and an opposing second side edge portion; the first end portion includes an elongated male connecting member having a web integrally connected directly with a first leg and a second leg extending from opposite sides thereof, the first leg being integrally connected directly to the first tapered side edge portion, wherein the web is connected directly to the end of the first leg and extends in a substantially perpendicular direction therefrom and terminates at the second leg, whereby the second leg extends parallel to the first leg; the second end portion includes an elongated female connecting member having a web integrally connected directly with a first leg and a second leg extending from opposite sides thereof, wherein the web extends substantially perpendicular to each of the first and second legs, the first leg being integrally connected directly to the second side edge portion and extends adjacent the interior surface of said at least one elongated panel to define a fold, wherein the fold is defined solely by a first leg extending substantially interiorly, contiguous, and parallel to the second side edge portion and terminating at the web, and the second leg extends away from the web in a direction parallel to the first leg and in the same direction as the first leg of the male connecting member; and said elongated male connecting member of said at least one elongated panel cooperatively profiled to slidably interlock with said elongated female connecting member of an adjacent at least one elongated panel thereby being joined in a substantially continuous plane. ### Claim 2 (depends on 1) The universal structural steel panel system according to claim 1, wherein said at least one elongated panel is of a substantially rectangular shape. ### Claim 3 (depends on 1) The universal structural steel panel system according to claim 1, wherein said at least one elongated panel is constructed of galvanized steel. ### Claim 4 (depends on 1) The universal structural steel panel system according to claim 1, wherein said at least one elongated panel includes at least two stiffening ribs integrally embedded to said at least one elongated panel, said at least two stiffening ribs extending longitudinally from the first end portion to the second end portion. ### Claim 5 (depends on 1) The universal structural steel panel system according to claim 1, wherein the tapered first side edge portion is integrally connected to the first leg of said elongated male connecting member. ### Claim 6 (depends on 1) The universal structural steel panel system according to claim 1, wherein the second leg of said elongated male connecting member includes a return lip extending along its length. ### Claim 7 (depends on 6) The universal structural steel panel system according to claim 6, wherein said return lip is integrally formed as a 90 degree bend at the terminal end portion of the second leg. ### Claim 8 A universal structural metallic panel system, comprising: a plurality of elongated rectangular metallic panels, each of said elongated rectangular metallic panels including: opposing exterior and interior surfaces, a first end portion and an opposing second end portion, wherein the first and second end portions are differently configured, and a first side tapered edge portion and an opposing second side edge portion; the first end portion includes an elongated male connecting member having a web integrally connected directly with and extending between first and second legs extending substantially parallel to each other from opposing sides of the web, said elongated male connecting member integrally connected directly to the first tapered side edge portion of each of said plurality of rectangular steel panels; the second end portion includes an elongated female connecting member having a web integrally connected directly with and extending between first and second legs extending substantially parallel to each other from opposing sides thereof, said elongated female connecting member integrally connected directly to the second side edge portion of each of said plurality of rectangular metallic panels, the first leg being integrally connected directly to the second side edge portion and extends adjacent the interior surface of said at least one elongated panel to define a fold, wherein the fold is defined solely by a first leg extending substantially interiorly, contiguous, and parallel to the second side edge portion and terminating at the web, and the second leg extends away from the web in a direction parallel to the first leg and in the same direction as the first leg of the male connecting member; said elongated male connecting member of one of said plurality of elongated rectangular steel panels being cooperatively profiled to slidably interlock with said elongated female connecting member of an adjacent one of said plurality of elongated rectangular metallic panels, wherein said plurality of rectangular steel panels are joined together by interlocking said elongated male connecting member to said elongated female connecting member; a first connecting member having a web portion and first and second legs, said first connecting member being connected directly to first end portions of said plurality of elongated rectangular metallic panels; a second connecting member having a web portion and first and second legs, said second connecting member being connected directly to second end portions of said joined plurality of elongated rectangular metallic panels; and wherein said plurality of elongated panels define a building component for constructing a building. ### Claim 9 (depends on 8) The universal structural steel panel system according to claim 8, wherein said elongated male and female connecting members define a plurality of apertures, said plurality of apertures configured and arranged in alignment with respect to each other when said elongated male connecting member interlocks to said female connecting members. ### Claim 10 (depends on 8) The universal structural steel panel system according to claim 8, wherein said elongated rectangular metal panels includes an insulation material disposed on interior surface said plurality of elongated rectangular steel panels. ### Claim 11 (depends on 8) The universal structural steel panel system according to claim 8, wherein the first leg of said elongated female connecting member is integrally connected to the second side edge portion and extends adjacent the interior surface of each said rectangular metal panel to define a fold. ### Claim 12 (depends on 8) The universal structural steel panel system according to claim 8, wherein each of said plurality of elongated rectangular steel panels includes at least one stiffening rib embedded to exterior surface. ### Claim 13 (depends on 8) The universal structural steel panel system according to claim 8, wherein said elongated male and female connecting members define a beam having a substantially U-shaped. ### Claim 14 (depends on 8) The universal structural steel panel system according to claim 8, wherein said first and second connecting members are substantially U-shaped, said first and second connecting members having first and second legs fastened to the first and second legs of said elongated male and female connecting members. ### Claim 15 (depends on 8) The universal structural steel panel system according to claim 8, wherein the second leg of said elongated male connecting member includes a return lip extending along its length. ### Claim 16 (depends on 15) The universal structural steel panel system according to claim 15, wherein said return lip is integrally formed as a perpendicular bend at the terminal end portion of the second leg. ### Claim 17 (depends on 8) The universal structural steel panel system according to claim 8, wherein each of said plurality of elongated panels is constructed of galvanized steel.
