Anyone replace the diamond plate on the front of their TT?

The stuff on there is thicker than I have seen on other trailers. If it was the thin stuff, it would have a hole in it. It got hit pretty hard. I couldn't see any damage on the inside of the pass through. But I'll see when I pull the old diamond plate off. I need to get the exact same stuff. It fits snug into the metal siding above it. Thanks all.
