[1] The company opened a foundry in Hurman Street, Butetown, in or adjacent to the site of the former Bute Shipbuilding and Engineering Works (at 51°27′58″N 3°10′16″W / 51.466°N 3.171°W / 51.466; -3.171).
The firm initially specialised in producing furnaces for annealing metals, one of which was built for Mountstuart Dry Docks in Cardiff in 1909.
[1][2] Immediately before the outbreak of the First World War in 1914, Curran's supplied several annealing furnaces to the Royal Arsenal in Woolwich, London, and had built a major munitions factory in Ward End, Birmingham.
In 1915 Curran's converted a building next to their iron foundry into a plant for manufacturing shell casings.
In 1985 Caradon Ltd acquired Reed International's Building Products division, including Curran.
