FOLLANSBEE, W.Va. -- Wheeling-Nisshin expects to begin production of a new product at its plant in Brooke County by the end of the year. The company is spending $28 million to add a new corrosion-resistant, hot dip coated steel sheet line at its Follansbee plant. Wheeling-Nisshin human resource manager Nick Cortese tells The Herald-Star of Steubenville, Ohio, that the company expects to conduct a non-commercial trial in May. Commercial production is expected to begin in late November. Wheeling-Nisshin's parent, Nisshin Steel Co. Ltd., developed the new coating, called ZAM. It's a combination of zinc, aluminum and manganese.
