do you mean U shape as in a deep and narrow channel or do you mean U
shaped as in a piece of channel? Big difference! What sort of
tolerence is required?
Some dimensions and where you are based would be useful.
If its just bog standard channel but to specific dimensions it should be
easy enough to get fabricated by ringing around sheet metal workers in
your area, if its too thick for them they will almost certainly know
someone nearby with a press brake that will bend up 3mm steel.
If its deep and really is U shaped you might have a bit more trouble.
Its a wide and flat u channel (thats actually a box in 3 locations)
forgot the height... but 1.5m long, about 40mm tall, and 350mm wide.
so the vertical bits of a U are 40mm and the bottom is 350.
I know I can ring round, but a personal recommendation helps
1)to get a good person, and 2)to keep good people in business
