Hi I know this is an older post
but i am looking to buy cds tube to build a cage, I emailed Mr Ramsey at Parker steel and this was his reply

Unfortunately we cannot do seamless tubes

So any other ideas where to buy

They say the size 31.75 outside diameter x 2.64mm wall, 12swg Cold drawn seamless carbon steel is the size we are to use which is a nats off 32mm
