This is what I am unsure of. With the tiny loads being placed on a 12mm thick I-beam would you conceivably get any twisting at all? The Universal column beams are always straight, the pipe always seems to have a bit of a bend in it.
Can anyone verify how much an ibeam would twist or flex under the kind of loads we are talking about (eg EQ6 with a 10" SCT)
Genuine question, I have no idea of the answer.
