Guy A Monfort, Adolphe A Bragard: Continuous measurement of the surface roughness of a cold-rolled product. Centre de Recherches Metallurgiques Centrum Voor Research in De Metallurgie, Holman & Stern, February 7, 1989: US04803374 (14 worldwide citation)

A light beam, e.g. from a laser, is transmitted onto the surface of a cold-rolled product such as steel strip. The light beam has a wavelength at least equal to the maximum roughness of the product surface. The reflected light energy is measured, preferably in the specular direction with respect to ...

Jean R Crahay, Adolphe A Bragard: Method for producing a metal product having improved lustre after painting. Centre de Recherches Metallurgiques Centrum voor Research in de Metallurgie, Fleit Jacobson Cohn Price Holman & Stern, September 3, 1991: US05044076 (1 worldwide citation)

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 sur ...
