Founded by the late Richard McNabb in May 1995, El Dorado Metals has continued the legacy of the McNabb Family in the lead industry that dates back to the late 1890's. At the turn of the last century, McNabb's were integral in the construction of one of the first Sulfuric Acid Plants built in the United States at Copperhill, TN, and working in the Viscose and Rayon Mills in the Shenandoah Valley during World War II.
