Abstract (en)
[origin: WO9806517A1] A panel (10) is formed from a sheet (12) of metal. The method comprises corrugating the sheet (12) with corrugations which extend parallel to one another in a first direction, and corrugating the already corrugated sheet (12) with corrugations which extend parallel to one another in a second direction, said second direction being inclined at an angle of at least 10 DEG to said first direction. The panel (10) is formed into a plurality of generally parallel upstanding ridges (20) separated by troughs (22). The troughs (22) have reentrant side walls (24). Each ridge (20) varies in width along its length in a regular manner and varies in height along the length of the ridge with the greatest height occuring at the narrowest points of the ridge.
