For a while, Ledgerwoods did what appeared to be chromed pillars, but they corroded quickly as I recall, so were discontinued.
The finish on those pillars varies a lot. Some are a satin uniform grey. Some look like they are painted grey. My Roadster posts are close to a fine hammerite grey, and I'm unsure as to whether they came like that from new. It was only three years old when I bought it, with a folder full of invoices, but nothing about the screen posts.
