I am trying to support 200lbs on a 14' span. i am a project manager for a mechanical contractor and am not privy to all the math involved. i would prefer to use angle, but am not opposed to channel if it's necessary. My gut tells me 4x4x1/4 is safe, maybe 3x3x1/4. i would like to use beam clamps on the edge of the horizontal leg, but can drill closer to the vertical leg if i gain some capacity by reducing torsion. any help is much appreciated. thank you in advance.
