PCT No. PCT/AU91/00212 Sec. 371 Date Apr. 1, 1992 Sec. 102(e) Date Apr. 1, 1992 PCT Filed May 17, 1991 PCT Pub. No. WO92/01087 PCT Pub. Date Jan. 23, 1992.Copper roofing panels and like contoured articles are formed from copper sheets electrolytically deposited on an electrode during an electrowinning process. The contoured roofing panels are formed by pressing planar copper sheets stripped from an electrode or by pressing a laminate of copper sheet and a plastics substrate. In an alternative embodiment, roofing panels are formed by electrodeposition of copper onto a contoured electrode.
