A cathode for electrowinning zinc is formed by an aluminum plate having broad flat faces and at least one narrow edge bridging the faces and a polyolefin copolymer strip bonded to the plate over the edge thereof. The polyolefin copolymer strip can include an inner layer directly bonded to the aluminum plate and formed of the bonding polyolefin copolymer and an outer layer of standard polyolefin.
