Sorry if I'm being thick here but would those require full welds all the way down or just spot welded?

I would say stitch weld would be fine.

Stich weld it, here's a little program that will help you out https://www.stitchweldcalc.com/

Make your weld beads about 50mm long with a pitch of about 150mm. the calculator will tell you how many are required per length.
Tip: Chamfer the flat bar on the underside where your weld beads will be and you'll get a stronger neater weld with less distortion.

Thanks for the link I'll check it out when I get back from work. Just to clarify, the cheap mild steel flat bar is fine right? There mild steel that's more silver buy has a code at the end which is very expensive or the black mild steel which is cheap?

Thanks
