A resilient corrugated building sheet having three or more plys of corrugated thin sheets secured together so that crests of one ply rests on the reverse crest of the contiguous ply, the crests of contiguous plys being the mirror image of each other thereby forming a plurality of open ended cells in parallel relationship. Each end of the cell is closed by an end plate, the end plates of each cell being interconnected by a tie to prevent displacement. The top ply is provided along one edge with an overhanging corrugation while the opposite edge is formed with a longitudinal socket. A plurality of sheets can be fitted together for roofing a building, a floor, decks for bridges, etc. For increased strength, the sheets can be formed in secondary corrugations and/or by filling the cells with a plastic material, formed in the cells or alternatively, with insulating material such as lightweight concrete.
