====Guest Keen Baldwins====
Steel production remained at the core of the company, but under increasing profit margin pressure. In 1930, the company combined its steel production business with that of rival Baldwins to form ''Guest Keen Baldwins'', which now held:<ref>The Times, 5 April 1930.</ref>
* Baldwins: Coke ovens at [[Margam]]; Blast-furnaces and steel melting shop at [[Margam]]; steel works and rolling mills at [[Port Talbot]]; blast-furnaces at [[Briton Ferry]]; lime stone quarry at [[Cornelly]]
* GKN: Dowlais Iron and Steel Works; Cardiff Iron and Steel Works; coke ovens at [[Cwmbran]]; limestone and silica quarries

In 1935, the company demolished the Cardiff works to construct a new production facility on the same site, funded by an issue of [[debenture]]s.<ref>The Times, 22 May 1935.</ref> Due to a resultant global shortage of pig iron, in 1937, the company fired-up the single remaining blast furnace at Dowlais.<ref>The Times, 16 March 1937.</ref>

During the [[Second World War]], all of the sites were heavily bombed by [[Nazi Germany]]'s [[Luftwaffe]], and the required investment meant that all of these assets were nationalised as part of the Iron and Steel Act 1949, resultantly becoming part of the [[Iron and Steel Corporation of Great Britain]].<ref>Hansard, 19 February 1951.</ref>

GKN were still highly reliant on the supply of good quality steel thus, in 1954, the business negotiated from the asset realisation company the repurchase of key assets from ISC, which were renamed ''Guest Keen Iron and Steel Co.'' In 1961, the company's name was changed again to ''GKN Steel Company''.<ref>The Times, 19 August 1960.</ref>
