1 piece floor vs 2 piece floor

[StruveD]

I did single piece in mild steel stitch welded. Its a bit more weight, but I really didn't like the idea of something tearing through the alum. floor and running me through.

Consider making an access hole beneath the prop flange, and having the best of both worlds. Also, the bits of gravel that make it into the tunnel will have a way out :-)

Turn the edge up on the panel at a suitable point in the tunnel area and this might stop some of the crud getting up there.

would 1.2mm galvanised sheet steel be suitable for the flooring , with regard to strength and weight ?

would it be useful for the firewall etc also ?

as there is enough being thrown away at work to do everything i need

to add to the info , its a BMW build car

Sounds about right, especially since it's free!

Just dont try and weld it in !!!!
You can always put bars across the floor to support the seats.

thanks guys

i was going to rivet the floor , as i have lots of rivets and an air riveter ,

thanks for the advice on the floor brace for the seat mounts, i have sourced some material for that as well , its some 100mmx25mm open box section , this will allow several fixing holes for the seat runners for fine adjustment if needed

Not sure what 'open box section' is - but I have gone with 25mm x 3mm strips on which to mount the seat runners. Avoids putting any more height than is necessary into the seat base - plus means you don't need to put crush tubes in - which you would with box section.
