I'm not sure I'd call them niche markets in the sense that a lot of industries would. It has more to do with specialized steel product. For example, one of the big developments in the steel industry over the last decade was the development of what is called the ultra-light steel automotive body, the ULSAB project.
Of course, in volume terms, it's not a niche at all. It's a very substantial business, but it's a top-of-the-line kind of product for the automotive industry. There will be other sorts of niches and so on, but actually, generally speaking, you want to be in a high-volume business if you're a capital-intensive industry like steel.
