Abstract: A corrugated panel structure, for use in the construction of a building wall or other structural application, includes a corrugated panel of broad, planar configuration and a pair of elongated caps mounted on opposite edges of the corrugated panel. Each of the elongated caps has a protruding central channel which is slotted to receive the individual corrugations of the corrugated panel. Each elongated cap is secured in place over an end of the corrugated panel by a rod disposed within the central channel and extending through apertures in the corrugations and end portions of the corrugated panel. Between the end portions, the corrugations form a zig-zag pattern of diagonally oriented planes which alternate in direction. Such corrugations extend in spaced-apart, parallel fashion between the opposite edges of the panel. The slots in the central channels for receiving the individual corrugations are diagonally oriented and alternate in direction relative to the directions of elongation of the elongated cap.
