Lead-coated copper is the copper industry's response for a strong, durable, easy-to-install gray metal finish on a copper substrate. The material has been available since the early 1900s.
Lead-coated copper does not extend the life of copper. Its purpose is to provide an alternative color to architectural copper applications. In addition, lead-coated copper runoff fulfills the objective of providing a metal whose runoff staining is compatible with light-colored materials such as masonry, limestone, stucco and light painted woodwork.
