A furnace at Panteg Steel & Engineering Co Ltd. Picture: Torfaen Museum. IT IS NOW 150 years since in the 1870s, the partners Davies, Pratt & Williams sold their Coed-y-Grig foundry to William Taylor of Swansea who changed its name to the Panteg Steel & Engineering Co Ltd. Panteg Foundry was at that time producing steel made using the open hearth process. William Taylor moved into Greenhill House adjacent the site to supervise its planned extension. The Panteg works had 12 melting furnaces each of 10 tonnes capacity and produced steel rails and fishplates. The site was not a total success and changed hands again (Wright & Butler) before being taken over in 1902 by the firm of Alfred Baldwin, a Midlands tin plate company who had formerly set up plate mills on the site, and the works from then on were known as Baldwins Ltd.
