The Patent Enamel Company Ltd, founded in 1888, moved to a purpose built factory in Heeley Road in the following year. Benjamin Baugh had begun to manufacture tough vitreous enamelled sheet wrought iron in Bradford Street In 1857. He combined with William Walters, and H W Elliott to form the Patent Enamel Co Ltd. The products were used for advertising on railway stations, hotels and public houses. Competition and the improved paper posters and plastics caused the business to decline and the company closed in 1965. The site was occupied by several small firms until it was destroyed by fire. Comet moved onto the site and later moved onto the Battery Retail Park.
