IMPORTANT: Minor shipping damage is more noticeable on jacketed tanks due to the uniform finish and the nature of the jacket. Extra lugs are installed on jacketed vessels for securing the tanks during shipment and they are normally palletized and shipped on a flat bed. Even so, minor cosmetic damage can occur and must be considered normal.
