ABSTRACT:
An appliance component is formed from sheet metal having a thickness defined by an elongated edge portion of the sheet metal. The elongated edge portion is rounded prior to applying a protective coating, such as a layer of porcelain enamel glass, to the component. Rounding of the elongated edge portions avoids the development of any thin or bare coating spots along the edge of the component which would be prone to rusting.
