Hello! I"m building a frame for a 10' wide by 8' high back drop that's made out of photography backdrop material. I'd like to build a frame that is light as possible but wondering if I should I go with 1/2" or 3/4"? This will be on a frame that rolls onto a field for marching band. Would 1/2" emt conduit be strong and heavy enough to hold it? Any advice?
