supporting 200lbs on center of a 14' span.
supporting 200lbs on center of a 14' span.
(OP)
I am trying to support 200lb duct on a 14' span. 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.

However these tables don't check torsion (shear) stresses or rotation. So that would be an additional check that would need to be done.
