Okay, something's been driving me crazy; I have no idea what this type of metal flooring is called; it's usually found in factories, submarines, ships, and other dangerous but industrialized locations.
Chequer plate flooring !!!!!!! could be !!!!
diamond plate, google image it.
I recognize the pattern, I sell that pattern in a 3'X3' rubber sheet, the solid rubber is used in dangerous locations because it does not conduct electricity. The 3'X3' rubber sheets fit together exactly with a very unique glue. Yes I have seen the same pattern in metal, but now you are getting into pricey flooring material, the solid rubber is around $5.00 a square foot and the metal flooring would probably come from a metal fabricating shop. Whatever you taste is, you are approaching into commercial flooring, flooring that is used in auto garages, factories, banks etc...
