Building materials of metal, namely, void formers made primarily of metal for producing cavities and recesses in concrete parts, shuttering parts made primarily of metal for building purposes; displacement bodies for manufacture of cavities in elements of concrete, namely molds made primarily of metal for forming concrete products

construction materials; namely, flexible metal gridding overlayed with preshrunk plastic surfaces for use as displacement bodies for making cavities in concrete, for making forms for concrete foundations and other concrete components of buildings, and for use in erecting temporary structures
