First consideration in dump boxes in my mind is what's the truck carrying and hw is it loaded.
A hopper loading sand or dirt is pretty easy on the floor, a loader or shovel dropping rock is a much nastier insult to the floor. That floor looks like a base drum head as the load hits it.
Back when Sewer Ontario started overtopping to make politicians happy thousands of loads of blast rock from quarries started riding to the lake in trucks with old bodies put back on. Patched floor don't mean much to a rock 5 feet in every dimension. Rocks poked thru the floor, add another patch. One genius found some road plate and wanted it on his floor. My bud Sam was out of work welding pipe, so he welded the plate in just like the owner wanted after the old floor and patches were cut out. Sam did it by the book and to the owner's expectation.
That owner was a proud peacock when them 3 rocks didn't even wow that floor. He got to the Lake and backed in, and when he hit the lever that body full of rock just sat still. Seems a telescopic cylinder in a doghouse has a capacity limit when it comes to lifting. Rocks pulled off fine with a dozer and chain, and when he hit the scale at the quarry he found out the truck was near capacity with all that plate.
Floor of a dump has to be elastic to a degree, packer is rigid because it functions differently. Sanitary dumps and boxes are complete nightmares.
I'm not sure AR-450 is the right alloy for a truck floor that will be in general use. Unless it's fully welded at edges and plug welded to crossmembers sufficiently to keep the assembly monolithic, it's going to crack in my opinion. The abrasion resistant sounds good to the owner, but he'd probably be better served with poly.
Rule #2, the job is paid in full before the truck leaves the welding shop.
