You may already know this but in case you don't...I suggest chairing the welded wire fabric up so it sits at the centerline of your slab...wire at the bottom isn't going to do anything to control your concrete cracks. Hope this helps.
I am not doing the concrete myself. A friend of mine is doing it. We still need to put the adobe(SP) under the rebar to raise it up. GD, here is the web site for the guys who did my fence. It has a 12' opening so I went with the steel frame. www.allamericanfencecorp.com Board More/Work Less! J$
I did in part because of the Brentwood enforcement. I use to keep it in my driveway in the summer so I didn't have to put the tower up and down and get some neighbors to help push it in the garage. It'll be in the garage in the winter months. Board More/Work Less! J$
I am looking into getting one of the steel framed awning with the sheet metal roof. We get strong winds and I have seen my neighbors vinyl awning/carports get torn apart. Thanks! J$
