Abstract

A metal product, such as cold rolled steel sheet, has a surface comprising a plurality of flat, smooth facets which are preferably 50 to 200 .mu.m across and which make up at least 30% of the area of said surface. The facets may be formed either by pressing a network of valleys in a flat, smooth surface or by flattening the peaks of a rough surface.
