Port Talbot Steelworks

Port Talbot Steelworks is a steel mill in Port Talbot, Wales. It is the largest steelworks in the United Kingdom and one of the largest in the world. Over 4,000 people worked at the plant until the last blast furnace closed in October 2024. Around 2,000 employees remain after this time, processing imported steel slabs to produce rolled steel products. The mill is in the process of building a 320-ton capacity electric arc furnace which would be operational in late 2027.

The majority of the steel slabs produced before September 2024 were rolled on-site at Port Talbot and at the Newport Llanwern site to make a variety of steel strip products. The remainder was processed at other Tata Steel plants or sold in slab form. After September 2024 imported steel slabs are used as inputs at those rolling plants.

The works covers a large area of land which dominates the east of the town. Its two inactive blast furnaces and steel production plant buildings are major landmarks visible from both the M4 motorway and the South Wales Main Line when passing through the town.
