The trellis on the East Door is a beef panel over landscape timbers,
I use "cattle" and "hog" panels in my garden. We have cut some in half so they are 8'--work perfect for pea and tomato fences in my 8 x 4 raised beds. Mine are left overs from calf duty. I've also put one (hog panel) vertically on the end of the bed. This year it's growing pole beans. DDIL's new calf barn have eliminated the need for them--so let's reuse! 
We have a lot of clay ground around the house and the raised beds are so much better than beating the hard clay soils--gets like cement when dry in the summer.
