There have been a few threads on here from us Kiwis.

Looking to build, based in New Zealand

Steel and tube charge 50nzd per m for stainless tube 25.4mm x 1.63mm (1x16SWG) 316L 6.000 1.00 ea 48.0000 m Seamless CD BA Stainless Steel Tube ASTM A269/A213 S116ST6 and 30nzd for their hygienic tubes. General Purpose Tube | The Metal Company charges 20nzd for their ornamental tube. Stainless ornamental tube is 14nzd a meter and steel and tube though. I didn’t realise cost would differ so much between diff standards

It’s a shame you’re on the wrong side of Christchurch! If you’re ever passing through Christchurch I got my steel pipe for my Lowrider from NZ Steel and Tube, very little web presence and quite grumpy, but very cheap and they cut it all to size for me. Is this the start of the kiwi invasion of V1Engineering? I’ll be interested to following the build for your table for the Lowrider as building materials are horrifically expensive here.

My dad built an LR3 recently using stainless 25.4mm x 2mm tube from Industrial Tube in Hamilton. For shipping you can get them to cut it down to a size that’ll go on a courier and it’ll end up cheaper.

NZ Steel and Tube was another option that seemed decent.

Ultimately you’ll probably need to be dealing with metal suppliers rather than Bunnings/Mitre10 so it’s a bit more legwork, but well worth it. If there’s a local steel supplier you could always give them a ring and explain what you’re looking for and if they have any suggestions. The stainless tube from Industrial Tube in Hamilton was dairy grade but with cosmetic blemishes from the welding, so basically a ‘byproduct’ so cheap for the size/weight/finish etc.

For my MPCNC build I used 25mm OD aluminium extrusion but that was from the before-times when 25.4mm wasn’t an option yet.

Also, as a word of warning, if you buy 25mm make sure you check the actual outer dimension before getting too caught up printing parts. Tons of places advertise 25mm tube that’s actually 25.4mm/1" nominal tube. There are also a bunch of tube standards that specify based on the internal diameter which can get confusing.

Sing out if you get stuck, I’m sure we can help.

Very late reply to this - but you can sign up for an account at Steel and Tube online, they cut to length and from memory last time I had steel delivered it was $15!

I have two posts from March which I will cut and paste here for your info, I’m sorry for whatever reason I can’t reduce the image size from the cut and paste : [quote=“jeffeb3, post:301, topic:40835”] Woodworkers make pipe clamps from the black pipes. They are heavy duty. Are they consistent at all internationally? [/quote] They should be, but I think I am correct in saying black pipe comes primed here , and black pipe is just not feasible because they’d rust in a minute so the woodwork s…

Might help with your search. And make sure you source your tubes before you start printing A lot of places claim something is 25mm but it’s 1". So make sure you have measured it before you start printing.

I just finished my LR3 with this from Steel and Tube. You can setup a cash account and they delivered a 2.8m length to a residential property.

1x 2.8m and 2x 1.6m cut to length and delivered for NZ$87. The quality is great and looks fantastic…certainly much better than the crappy Bunnings galv tube which is similar price.

$8NZDp/m is pretty nice!

I think I was forced to for food grade stainless 32mm for the BruteCNC which was a bit pricey!

[Mattpugh96 (matt)]

Hi guys another NZder here trying to locate tubing for a lowrider build is struggling to find 29.5, 30 or 32mm the best I can find currently is 31.75mm stainless would this work?

[jono035 (Jono)]

Yeah, that’s what most people end up with. What wall thickness?

[Mattpugh96 (matt)]

it’s got a 1.5mm wall thickness

[jono035 (Jono)]

That should be ok. Is that from Steel and Tube? I think I’ve seen that a couple of places as stainless steel handrail tube.

I was gonna go silly and get 3mm wall galv steel pipe from Magellan Imports for the fun of it. There was also sdalu.co.nz but I don’t know anything about them beyond having googled it up.

[Mattpugh96 (matt)]

yeah, I’m m getting in through steel and tube seems to be the most cost effective

[jono035 (Jono)]

For stainless, yeah. For galv steel, Magellan Imports was $48 for 5.8m I think it was and in the past I’ve rocked up with a reciprocating saw and sweet talked them into letting me hack it into transportable lengths in their yard, which is nice.
