Abstract

A material handler formed from isotropic textured aluminum sheet rolled by rolls indented with spherical media, such as steel ball bearings, producing a sheet with a low coefficient of friction relative to particulate matter like flour. The slippery sheeting may be used to make tanks, silos, conduits and guides to facilitate storage and flow of the particulate matter.
