Abstract
In processes in which protective metal coating materials are applied to iron-based substrates in the form of liquid films which are then solidified by cooling, the metal coating can be contacted with a roll such as a tower roll, conveyor roll or guide roll, while the coating material is capable of transfer, by the use of a roll having an exterior ceramic barrier or surface having a thickness of at least about 20 microns whereby the surface of the coated substrate is not unduly adversely affected.
