Steel ring or pipe

Sounds like off cuts from a chemical engineering or oil project, but no idea where to source them.

 

Why not just purchase a used oil drum. Most 45 gallon drums tend to be roughly 60cm wide, just cut it down to the height required.

Plenty on eBay, maybe a local garage or haulage company might have some.

Oil drum might rust through too quickly for the intended purpose.

 

Does it have to be steel.
Was thinking of those concrete pipes they use under ground.

 

Well I didn't say it would be easy.

It's just that I can't think of any steel pipe other than stuff you might find in heavy industries, oil refineries or large factories, it will probably have similar problems.

 

I've used 'animal feed' plastic barrels. Cut in half with drain holes they make good planters.
I've got five on the allotment planted up with leeks at different stages. Unfortunately most are bright blue, but I've managed to source some black one's.
They are virtually indestructible and often seen on ebay/gumtree for around £20

If you wanted them tarted up, they could be wrapped with reed or bamboo mats etc.

 

If you go with the washing machine drum (has been suggested (GQT) in the past for fig trees) or plastic barrel suggestion you can always put wood cladding round it.

 

Hi @Loofah Have you thought about asking a blacksmith? (Not a farrier, someone who welds things for builders etc). They can often source the iron (or might have bits, and can create a cylinder for you.
