Where to get rectangular PVC tube

I need some rectangular PVC white tube, say 20 x 40mm, or 25 x 50mm for a construction project I'm working on. I can't find anyone in UK who can supply this, But surely this must be available? I can find end caps for it, which surely means that the tube must exist? Can anyone suggest where I might get this?

Thank you - Rowan

Hi Rowan,

would electrical trunking suit?

David

So if you can obtain the end caps, maybe ask the supplier if they can supply matching tube or recommend a source?

Are you sure the end caps are for plastic tubing? it sounds like they may be for steel tube as used in desks and tables etc.

Try these for 25 x 50

No connection but it seems expensive. £340.50 for 25 3mtr lengths.

Could try TP Extrusions

or Sinclair & Rush

The end caps that are available may be targeted to steel sections eg table legs /chair legs

Or the end caps may be repair items for imported plastic furniture. Could you get square drainpipe and cut and glue it?

Yes, I recognise that the end caps that I have seen may be intended for metal tube.

TP Extrusions seem only to make tube to order, which means they have massive minimum order quantities.

Sinclair and Rush only make small tube, max size 23 x 11.5mm This is not large enough for what I need.

Any other ideas?

Thank you - Rowan

I suppose I could try this, but it would make the job much more complex than it needs to be if I could find the right size tube.

Thanks - Rowan

They only seem to supply these massive quantities, which is not cost effective for me (I only need about 2m of tube).

Thanks - Rowan

No, I don't think it would. I think the opening side would make the finished contruction much weaker. I suppose I could just glue the lid shut. But in most cases that I have seen the trunking is not truly rectangular, so it wouold be much more difficult to cut and glue accurately. I think I've got to find just plain rectangular tubing.

Thanks - Rowan

Some sizes are available here in North America, see link below. Multiply inch sizes by 25.4 for mm conversion

The second link by Journeyman looks ideal to me: **LINK**

Form their web site the largest rectangular size they have is 23 x 11.5mm, which is too small for me. They supply larger square sizes, which I may have to go to if I can't find rectangular, but their mimimum order qty is £24 which is more than I was hoping to spend.

Thanks - Rowan

Rowan, try searching for "PVC batten" you may find what you are looking for.

Having no idea what it is that you are wanting to build; it is obviously unreasonable of me to comment, but: I would be tempted to consider using pairs of 25x25 in place of 25x50

Does it have to be plastic?
Here's some aluminium box section with a white finish in 2m lengths

That was a good suggestion, but despite fairly thorough searching, I still haven't been abkle to find what I am looking for. So still looking, and would still welcome any suggestions.

Thank you - Rowan
