cutting it down depends
some companies have 2 to 3 thousand m every 3 to 4 months 70 % being long
you have a guy cutting that down costs its cheaper to get them straightened
as i say rollers too tight .......too loose and its still bent the other end
aom has it correct that if its a good straightener with a decent machine he puts that gear back into circulation and you will not have that spiral groove situation. it does make cost effective sense
its a choice to cut tube down so you take your choice neither is free

aom has it correct on this occasion
the process which you describe is the correct method for straightening scaffold tubes, you will be able to see spiralling marks along the length of the tube, however the spiraling should not indent the tube at all, if you can feel grooves in the tube that has been straightened the machine being used has been poorly set up and the rollers aligned incorrectly.
Cold rolling a scaffold tube through a correctly aligned and maintained reeling machine will not weeken the tube in anyway, as the tube is ever so slightly compressed whilst reeling through the machine. Only by kinking, cutting or applying excessive heat to the tube will you affect the integrity of the steel and weaken it.
We have been straightening scaffolding tube for over 31 years, and have had direct links with the original designers of the reeling machine.
Hope this helps
