Can't find 1.6mm steel. 1.5 ok?
As in title. I can find loads of places doing 1.5mm thick ERW SHS. Can't find anywhere doing 1.6mm thick which is the metric translation of 16
SWG (What the book says to use). So, is 1.5mm thick ok?

the difference is 1/10th of a millimeter!!!!
or about 0.004 inch!!
Nothing to worry about mate 
1.5mm will be just as good as 1.6 mm

Good good, that's what I figured :-). Just thought I should check though. I wouldn't be surprised if the slight difference multiplied by
the 30 ish meters of steel actually made an important structural difference but I guess it doesn't.

You'd probably save a few grams!

You could just buy imperial SHS and use that instead.
Personally i would go for the stronger box section, unless you realy want as lighter car as possible.

25mm x 1.5 RHS tub has only 90% of the metal in it as 1" square 16swg. That will equate to 90% of the tensile strength but probably not
torsional stiffness.
