I called the manufacturer of a perforated steel square tube, size 1-1/4x1-1/4x14ga (0.0747"), to get properties, such as section modulus, S, but all they could tell me was the gage. I left the question on their recorder, but they haven't called. The tube has holes on all 4 sides, down the center.
I would imagine the strength is roughly 90% of a non-perforated tube, since the holes are down the center, where the neutral axis is. However, the smallest square tube in the AISC is 2x2x0.1875". Is there another source for engineering specifications on thin wall steel tubing such as this?
