What gauge of metal should I use to replace the floor

Recommended Posts

I've been working on my 720 for a while, and I've recently discovered that the floor pans and rocker panels on the truck are rusted out because it's covered with vinyl and carpet. I would like to focus my attention on the pans and rockets because the area where the cab is mounted to the frame is rusted out as well. I would like to know how thick of metal I should get, that way I dont spend too much but still get some good replacements. Any suggestions?

I try to buy 20 or 22 gauge hot rolled steel sheet. Cold rolled is too stiff for working on a wheel or for beating into shape.  20 is preferred but  my supplier does't always have it in stock.

The floor is thin but you’ll have to get thicker stuff to rebuild the structure underneath the floor cab  mount - like 16

i have similar issues where my body mounts to the frame and i got some 16 gauge steel remnants from work. still havent started the repair. hopefully when the weather gets better this spring/summer ill have time. i have the carpet pulled out and a new one to replace it, but for now when its raining the tires sling water up through the small holes in the floor and get my pants wet.

I nearly put my foot through the rusty floor when I got my 720. I needed a quick fix, and just screwed several layers of galvanized metal roof flashing over the problem areas, expecting to do a proper replacement later. It's been five years, though...guess it's not too high on my list!
