I'm in the process of enclosing my open trailer and I need some diamond plate. Where is the best place to get it? What I'm going to do is basically frame a enclosed section like a pole barn, 4x4's with horizontal boards. Then wrap it in metal siding. I'm going to make the sides 3-6 inches taller than the roof to form a wall for carrying items like ladders on the roof. I want to wrap this top lip in diamond plate as well as add some diamomd plate accents. For the door I'm going to leave my gate on ,then add a section over it that will hinge up and stay up with the help of gas shocks. When I close the top door it will close over the lip on the gate ,then have a hasp on both sides to lock it up. I think this will be a pretty nice setup, 1/3 open 2/3 closed. Anyway if you have any suggestions on where to buy diamond plate or any other helpful stuff I would appreciate it.
