Hi I'm looking for flat pack chassis based on Mazda mx 5
Thanks rob

It's called lengths of ERW and most metal merchants can supply!

Try http://www.talonmotorfabrication.co.uk/
They sell MX5 chassis and flat pack kits, but it's not clear from the shop if they'll sell a flat-pack of their MX5

The guy that runs it posts on here sometimes http://www.locostbuilders.co.uk/members/Talon%20Motorsport/

What is different erw tubes and mild steel tube ?

ERW just means electric resistance welded, Its the process for making most hollow sections.

Mild steel tube is cheaper can I use to welding with arc welder

We use a few different steel stockholders and none do small box sections or tubes thinner than 2.5mm in normal mild steel tube, all of the thinner ones come as ERW. I think ERW is a harder metal also, we also refer to it as bright rather than mild.

I have been a welder for twenty years and I'd still not tackle a chassis with a stick welder unless it was 3mm! and a Rangerover

are we talking about a flat pack kit for a mx5 based roadster? then talon is where you want to be looking
why not try the haynes roadster forum phil form talon is there regular and from what i have seen his work is of good quality and his prices are pritty fair.

ps tube is either seemless (eg made with no join) or erw (made from a flat section shaped and welded)

Industrial Metal Supplies do ERW 3.3m 25x25 mm 1.6 wall for about 12 quid a length
