Aluminized steel is the budget-friendly choice. It has a protective coating that holds up well, but once that coating wears it will eventually rust through, especially in salted winter climates. The stainless option is T409 stainless, an automotive-grade steel built to resist rot, and it will typically outlast the truck. T409 is not polished show-grade stainless, so light surface rust or discoloration can still show up over time. That is cosmetic only and won't affect performance or service life.

  Why can’t you ship to the USA? I had a Flo pro I bought in 2016 sounded great. Had the aluminum and it rotted out. Wanting the stainless. 2009 dodge ram 2500 6.7 Cummins 6.4 bed
