Abstract (en)

A system for carrying out one-side zinc hot dipping process of the type wherein a steel sheet having a film of an anti-plating agent formed on one surface thereof is passed through a molten zinc bath to plate the other surface of the steel sheet with zinc, and the anti-plating film is then removed by peeling to produce a one-side zinc plated steel sheet, is arranged such that the anti-plating film on the steel sheet does not contact with any rigid member such as a deflector roll while the sheet is moved from the molten zinc bath to the anti-plating film peeling site, thereby preventing formation of dents in the sheets, which is otherwise caused by zinc particles entrained on the anti-plating film emerging from the zinc bath.
