Castle Metals UK (Head Office)


Set up to serve the Petrochemical, Chemical and Oil and Gas Industries Metals UK Ltd began supplying Duplex, Super Duplex and Nickel Alloys in November 2002. To complement these grades of material Metals UK bought E Hardings & Sons and LOKS Plasma Services in 2003 and KKS in 2005, firmly embedding the Metals UK Group in the market place as a unique supplier of 21 grades of material with every known method of processing available. In 2008 A. M. Castle & Co (USA) were looking for a European acquisition to expand its international presence and Metals UK fulfilled all their requirements. Now when the global market buys, it buys from us.
