Hello,

The aluminium floor panel in my 90's rear tub has started to corrode through and has already corroded through entirely in some areas. I would like to know what people would suggest I do to repair this? My first thoughts are to cut the entire sheet out, leaving a 1-2" lip around the edge, to which I could then rivet a new aluminium section in place. Would this work, or would the thickness of the lip prevent the floor panel from meeting the cross struts / braces underneath? As a matter of interest, are the cross struts attached to the tub floor or is the tub floor simply resting on them? Would I be better to remove the entire sheet and fit a new piece in place? Either way, I will be putting a rubber load space mat onto whatever does go in place but I have never really heard much on this problem before

Thanks,
-Tom

unless your going to remove tub and rebuild it ,just lay a piece of aluminum checker plate you can get load liner kits of checker to rivet in place

I've seen various chequer plate kits on the web but they are exceptionally pricey. I will measure up and try to get hold of an ally sheet which I can paint up, rivet over the top of the existing sheet and then cover it all up with a nice piece of rubber matting.

Thanks,

i have a similar problem in my 88 went to the local agri engineer and he is going to supply me with a 8 ft by 4 ft of 2 0r 3mm( cant remember) chequer plate for 60 ish quid a sheet depending on the price of alloy at the time

The steel cross bars are riveted to the floor but all but a few are easy to get to with a drill bit. There are a few welds along the sides and back that can be drilled out and then the floor can be removed with the laterial ali braces. If you have corrosion comming throught the floor then you probably have coroded ali braces from resting on the steel cross bars. I am getting ready to do this job myself soon and will replace with a piece of diamond plate because of the thickness. that way there is only the one piece floor that is easy to take care of. Because of all the steel touching ali throughout the tub it is a good idea to paint each piece and then put a barrier between the pieces (dum dum, not setting sealer, sylicone ect). This is how I plan to do mine but like any plan, I will flex when the monkey throws a wrench. If I am way off please let me know.
