Abstract
A method and apparatus for handling sheet metal stampings such as automotive body panels. A rack is disclosed in which a plurality of runner assemblies are positioned proximate the floor of the rack with each runner assembly including a galvanized steel base member secured to the floor structure of the rack and a top member secured to the base member. The top member includes a galvanized steel substrate and a cladding applied to the upper face of the substrate. The cladding comprises a lubricous material such, for example, as a polypropylene so that the cladding not only provides a mar-resistant surface to protect the finish of the sheet metal stamping but further provides a low friction lubricous surface to facilitate the sliding movement of the stamping along the runner as the stamping is moved into and out of the associated rack structure.
