Hinging a new boot floor!

No way that ****ty, rusted, pitted 1.5 (ish) mm steel is structural. If it was my disco would have fell apart by now.

Can't be arsed to find the thread as it's a few years ago but I'm sure I remember a guy who fitted a thickish sheet of aluminium and marine sealed/riveted it down as a replacement boot floor on his Disco....

The question is why a hinge or hinges?.
Non I know of are waterproof therefore will allow water into the boot area, if a large inspection panel is required then a removable panel with X number of screws plus a gasket will complete the job a lot better.

If you look at the seatbelt mounts, they are actually bolted to the floor with a reinforcing bracket underneath that bolts to the chassis. It is held to the bracket on the floor with a pin with a tiny split pin through the end.
I would imagine that if you fixed the front end securely as far as the seat belt mounts, then made the rear section removable you wouldn't have any problem.
I did spot on ebay last night you can get floor repair sections now, which would make this option a possibility without butchering a new floor.
And yes, they can be bolted/riveted into place as they are not classed as structural due to the separate chassis construction. Technically only the sills and rear crossmember are structural items

Why is it welded at manufacture then ?

Welding can be done by robots, and is therefore quicker and cheaper, and also more secure if done correctly.

Thanks for thoughts, but in the end the sender unit turned up so welded the floor in on the top edge with seam sealer on the whole bottom lip, I can grind off the welds If I need to remove the floor at a later date!
All back fitted up and sound for the mot in a weeks time!
Here's hoping!

I swapped the boot floor in my disco 3 years ago with a chequer plate and used stainless m12 bolts every 150mm and it's passed its mot every time
The mot tester has a disco himself and is doing the same to his next year
