The Steeliness website is about naval armour plate and the armour plate industry. It gets its name from theĀ  Admiralty’s Inspectors of Steel who were based in the main centres of steel production, The Sheffield office had the telegraphic address of ‘Steeliness.Sheffield’.

Steeliness hopes to increase the understanding of the naval armour plate industry from its beginnings in the middle of the 19 Century to its decline in the mid 20 Century. During this period Sheffield was the main centre of British armour manufacture and the profits from making armour enabled the Sheffield firms to create a network of shipbuilding and ordnance companies across Britain and internationally. Steeliness works closely with the Sheffield Industrial Museums Trust and Museums Sheffield to explore the history of armour manufacture in the City and the impact it had on its industrial development. The armour makers built national and international networks to share and control armour making technology and Steeliness explores these how these close relationships worked in practice.

Steeliness draws its material from a wide variety of archive, without whose help the research that underpins the website would not be possible. The website will publish articles based on this research as well as original documents and transcripts about naval armour plate.
