It's some pretty solid wood. Allot of 2 x 4's and 4 x4's and 4 x 6's. The wire is concrete wire which we have found is stronger than chain link of any strength we have used. It is much thicker. Works well when they bite on it as well as they can't twist it up like they can chain link.

This has worked well for us. There is no way they can move that fence.

Out of curiousity what are you using?
