So I had wanted to find one of these signs for a while. Either you can't find one or they want to much for one that would be for sale. So I am a graphic Designer and decided to make my own. Found a picture of one of these Warning signs and made one myself. All of them are UV printed onto Brushed metal. Two of them are bolted to the back piece. The other two are printed just on a single level. They really look amazing in person.
