Front tube bar

Was typing same time John Mate!
I assume they’ll be 40NB (48.3mm OD / 3.25mm ) which is fine

Hold the Fort, are they requiring welding plates to the chassis John Mate?

Due Diligence required here Johnstar
Competition bred sliders are traditionally designed with a chassis welded tapped plate that accepts the sliders matching bolt plate for ease of throw away after the race/challenge.
On our daily vehicles this chassis welding requires full engineering certificates
Here’s hoping you’ve been advised by the seller and or it’s a new lateral/sideways U bolt type design

Can't go wrong with Millweld.

I personally can't recommend Raslarr after the experience I had with them 6 or 7 years ago, maybe they have changed but I had a few issues with the workmanship and they were not interested in making it right.

40NB (40mm nominal bore) with a 3.25mm wall will be 46.5mm OD ��. Nominal Bore tube will normal have a schedule rating and this is what determines the wall thickness.

So if you want a 50ish mm OD you will need to use 40nb with a 5.2mm wall thickness.

Also check if their bars are adr approved. Airbag compliant etc etc. These details are what insurers will be looking at if you were to run into someone or something. No compliance no insurance.

The only way to get this compliance is to have the bar tested for impact and destruction.

The 40Nb pipe we purchase is always 48.3mm OD with varying wall thicknesses, is this just a galvanised thingy, black maybe different?

No you are right I was confused. It gets a little hazy sometimes. I deal with tube and pipe at work and they are measured differently. I was right about the schedule rating though.

So yes your 40NB has an 0D of 48.3mm and a wall thickness at 3.2mm makes it schedule 30. Now if you go to the right place you can get other schedules as well.
So Schedule 80 is 5.08mm wall thickness. Schedule 160 is 7.14mm wall thickness.

For what it's worth we made a set of sliders for a new dmax at work and used 40DN (or NB) schedule 80 (5.08mm wall).

Sorry about the above confusion...
