I decided to have these tiles installed as the ceiling of my deck roof. They look absolutely amazing and realistic.  Lightweight and extremely easy to put up, I opted to attach them with oxidized nails for an authentic look. They are weatherproof and can even be painted if I ever get tired of the rusted tin look. Each tile measures a generous 2' x 2' and the variations in each are unique. I do recommend laying out the tiles prior to installing to achieve a cohesive overall effect.  
These tiles could be used in a variety of ways such as a kitchen back splash, an accent wall, ceiling light medallion, refacing cabinet doors, around a tub surround, and the list goes on.
