The short answer, to the OP question is: They can't.
The steel supplier will likely be quoting from the British Standard for tolerances of form on hot formed hollow section. I don't have to hand, but they are not small numbers; quite high percentages of length and section size, etc. One can control the tolerances, to a point, when welding together. Other than that, epoxy or shim. The one thing I don't get about shimming is that if it isn't done over the whole length of the clamped joint, joint stiffness benefits are lost. In that regard, epoxy is better.Last edited by CharlesJenkinson; 18-02-2014 at 09:42 AM. Reason: answering OP question
