Copper is easy to shape and form for many industrial, manufacturing, building, and construction applications. It conducts heat and electricity and resists corrosion. Copper sheets and plates are solid, flat pieces of metal that are often used for roofing and manufactured into automotive and electrical parts and components. Copper flat bars have rectangular or square cross sections and are available in different material grades for specific applications. Copper rods are solid lengths of metal that resist wear and corrosion and can be cut-to-length for specific applications. Copper round tubes are hollow, durable, and easy to form and shape. Copper foil is thin, easy to cut, and conductive.
