Rolled product with textured surface for improved lubrication, formability and brightness

摘要

A metal sheet for making rigid container products, and a method of making the sheet. The sheet has a fissureless surface that retains minute amounts of lubricant in generally uniformly spaced apart elongated micron-sized depressions, the depressions providing a quasi-isotropic surface texture which, in turn, provides a substantially uniform distribution of friction at the interface of the surfaces of the sheet and a tool employed to form the container products. The depressions, in addition, provide the product surface with a high degree of specular reflection of light and thus a bright surface having a high level of distinctness of an image reflected from the surface.
