/diy/ - Do It Yourself

What do you mean plastic beams? Like extruded plastic lumber or plastic PVC pipe? Both would be hard to work with. The extruded plastic is a pain in the ass to cut and drill and is heavy as shit and the PVC pipe would be too flexible unless you used large diameter thick walled stuff in which case it would be really expensive.

If you want to do less cutting or if you're better with metalwork than wood you can use EMT, that's the metal tubing you see outside buildings that contains the electrical wires if you're not sure. With that stuff you just have to flatten the ends, bend them to the right angles, drill them and bolt them together. The only problem is you need to cover them with one large sheet of material or figure out some fancy way of attaching leak proof fasteners to them that will hold whatever type of panel you are using.
