Yes, it has metal edges, I'm pretty sure it is Duragilt also, from the pictures I see in the Betterbee catalog. The bees sure do seem to like it. I'm going to put in an order soon and am going to get some black Pierco to try. I have a heck of a time spotting eggs. Wish I had the eyes that I had twenty years ago, sigh... But I probably will get some of both, the bees draw out the Duragilt really fast. The two swarms I picked up are growing fast, I need more frames and deeps.
I have decided that this is why all the beekeepers that I have seen in person or in pictures have hives that look neglected - who ever has spares so that they can fix them up and paint them?
