Walt: What about using just AL flat bar 3/16-1/4 x 2 instead of rectangular channel? Seems like it would be easier to bend, and using the same material easier to bolt it together with cross pieces. For curves there might be two methods 1. use thinner pieces, 1/8"(?) and build up the curve in a jig, bolt them together and the cross pieces and it would hold the curve shape; use the 3/16-1/4 pieces used for straight sections; 2. use the same 3/16-1/4 x 2 stock. If there is torquing, if bending as before would not work you could always put diagonal wire & small turnbuckles underneath (X pattern) and adjust as necessary. And wouldn't flat AL be easier to bend with a radius bender? The fence & iron works company I use has one to bend round or flat bar, looks pretty much like a bigger version of what we use to bend rail. Using flat AL stock you could still weld it together also. This method might need a couple more cross pieces and maybe the sections would have to be shorter, 4' or 6', rather than 8', maybe not. It doesn't seem to me you would need a thicker Dibond AL sheet. (Don't take the suggestion of thickness of flat stock too literally since I've never worked with flat or channel - using flat stock is just a concept.)
