Metal Floor Tiles

We plan to install metal tile borders in our lobby. There beside these intalling.
Boder will be just the metal tiles, the remainder will be porcelain tile.
Any advice or ideasare greatly appreciated.
Thank you

I am a builder, and I specialize in kitchen remodels and bathroom (tile and stone being my specialty). I realize that I do kinow all, but I've never heard of metal tiles for use on a border. Do you need more information?
