ABSTRACT:
A method of continuously producing a one-side-only zinc coated ferrous metal strip initially having zinc coated on both wide surfaces, as by differentially hot-dip coating, and with the zinc on one of the wide surfaces being in the form of a thin film which is transformed into a thin zinc-iron intermetallic layer by applying heat to only the wide surface of the strip having the zinc in the form of a thin film and abrading the surface of the intermetallic layer thus formed by brushing to effect complete removal thereof, leaving the other wide surface of the strip coated with zinc.
