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. |
