Zinc Coils are part of our range of metal foils. With 169 variations, they come in a wide array of thicknesses, temper grades and surface finishes to suit different applications. These coils can be used for chemical protection, batteries and shielding thanks to their corrosion resistance, electrical conductivity and EM shielding properties. The large variety of Zinc Coils we offer allows scientists and engineers to select the optimal foil for their specific research, prototyping or production needs.
