Tudhoe Iron and Steel Works
of Spennymoor
1852 Weardale Iron and Coal Co developed another processing plant at Tudhoe near Spennymoor, comprised of two forges and two mills for working the Weardale pig iron produced at Towlaw Ironworks.
1856 the Tudhoe works were extended, and two additional forges erected.
1861 The company installed a set of small Bessemer converters at Tudhoe.
1870 two blast furnaces were erected to smelt this newly-discovered Cleveland ore.
By 1893 only Weardale and Spanish ores were smelted at the Tudhoe furnaces. By this time the Weardale Iron and Coal Company had extended its activities so that it carried out all the operations necessary to convert iron ore into finished product.
