Just a quick interjection. In my high school
theatre, we had schedule 40 battens which had to be replaced with schedule 80. For the high school alone, schedule 40 was enough, but do to loads being put on them from touring shows we needed 80. The pipes were actually bending, one was even bent at a 30 degree angle downward on the one end. So it really depends on what you want to load on them, not what standard is. When the rig was installed, they went off of standard. If they had asked a touring show what it needed to be while the
theatre was being built, it would have been schedule 80 to start. So start at schedule 40 and determine if that would be enough, don't just use it because it's 'standard'.
Also, make sure your arbors can handle the weight too. They just installed a whole new lighting
system in the smaller
theatre and had to take away all the nice, new, shiny Source Fours and replace them with Colorcraps
. Reason being, someone didn't think to look at what the arbors could handle weight wise with new pipe, cable, raceways, and fixtures
. The Colorcraps weigh about half as much as the Source Fours. So this was very upsetting since I might have to do a show in there soon
