Folks,
Last winter, I had a stack of a 40m full size beam and a tribander wiped out
by a storm. The point of failure was the steel tube that I was using which
bent over and caused a knock on affect which destroyed the beams. We have
learn the difference between pipe and tube the hard way.
There are several steel stockists here in Ireland, but they only carry
standard galvanised piping. I have checked the towertalk archives and there
is a lot of discussion there on the merits of Chrome-moly tubing and the
different grades that would be suitable for this type of installation.
However, these seem to be US standards and the steel merchants here are not
familiar with them.
Can anyone point me in the right direction ? If someone has purchased tubing
for a similar project, I would be very grateful if you could send on details
of what tubing you have used.
