A high strength frusto-conical or conical structure utilizing an integral flanged reinforcing grid is disclosed. The structure comprises a skin plate having a generally conical shape, with a plurality of upstanding integral ribs. At least some of the ribs are configured in evenly spaced right and left spirals. Other ribs may extend along conic generatrix intersecting the spiral ribs at points where right and left spiral ribs intersect. Each rib includes a narrow flange at the inner edge, lying substantially parallel to the skin.
