Manufactured from U.S.A. made, 1" DOM steel with a thick .120" wall. 100% TIG welded. Available in chrome, or raw steel. The chrome finish we offer is done by a local custom chrome shop here in Nashville TN. Because of the amount of business we send to them we are able to offer a quality chrome for much cheaper than most people can obtain on their own.
