This is a little cheaper construction than I expected but should be OK, we will see how fast rust gathers. It was easy to put together but if all the bolts are tight the two long sides were not parallel. We loosened all the bolts, used tapcons to attach the sides to a block wall where we wanted them (and parallel with each other) and then tightened up the connectors. The fact that the joints aren't tight isn't obvious. The trellis makes a huge difference to a flat wall with a very boring window so I am happy with the purchase..
