Delivered promptly and well-wrapped Reviewed by

I think this stuff is the same wherever you get it. But the prices are about the same as my local steelyard, there's a wider choice of sizes, and because it's being delivered, I can get longer pieces than would fit in my car thus saving a bit on paying for cutting.
