Britain’s steel and car industries are intertwined like very few others. Back in the dimness of time, the British steel industry had to develop new techniques to make large steel sheets that could be bashed into large car panels for the then-newfangled unibodied cars.

And names like Pressed Steel-Fisher became sole suppliers of car bodies to some of the big names in the UK car industry, such as Rootes and Jaguar. Pressed Steel, in fact, grew to be the biggest provider of car bodies and tooling in the world in the post-WW2 era.

But its grip on the UK market has slipped in more recent times – with pressure from China and competition from alternative materials such as aluminium and carbonfibre.

China, for example, has the capacity to make more than 800 million tonnes of steel a year, compared with the UK’s 12m tonnes.

UK steel, however, is higher in quality and more suited to complex applications in modern cars design – for example, in high-strength tailored blanks and galvanised anti-corrosion coatings.

Steel has also been caught up in the general trend to offshore car parts supply. Since the 1980s, when a UK-built car typically featured at least 80% local content, various factors such as labour costs, energy costs and currency peaks have reduced that to around 30%. Only recently has it begun to climb back up to 40%.
