摘要： A method of bending a corrugated sheet about an axis extending at right angles to the corrugations is disclosed wherein a plurality of rib formations are pressed in those corrugations having their apices nearest the axis, the rib formations all projecting from the same surface of the sheet relative to the axis and extending at an angle to the corrugations over at least part of the side portions and at least part of the intermediate portions of the corrugations. In one form of the invention the corrugated sheet comprises a metal cladding sheet. Also disclosed is a corrugated sheet bent about an axis extending at right angles to the corrugations including a plurality of rib formations projecting from the same surface of the sheet when viewed from the axis, the rib formations being at an angle to the corrugations and extending over at least part of the side portions and at least part of the intermediate portions of the corrugations.
