A:Answer Hello, sam. We appreciate your inquiry. The Frigidaire gas cooktop features a cooktop surface that is typically composed of a durable material such as porcelain enamel, tempered glass, or stainless steel. These materials are commonly used on cooktop surfaces due to their resistance to heat, stains, and scratches. The grate material of this model is cast iron with a grate quantity of 2, and the grate style is continuous. We hope this information helps! - Christi
