Stainless Steel Rodent Catch-alls

Has anyone found or tried a stainless steel rodent catch-all?

I have a few areas where some processing aids are corroding even galvanized catch-alls.

Plastic would be an option if there are no stainless products available.

I would expect aluminum to be less expensive and sufficiently resistant in most cases.

We just use the "cheap" galvanized ones.  The units in the chemical storage room just get replaced more often ~ and the ones that people manage to smash with lifts/jacks (one more reason not to splurge on stainless).

Never seen one---------quick google search didn't show any either

for the cost of galvanized, just replace them                    do you have an exterior door on your chem room?  If not, you can probably justify removing that trap---particularly if you've NEVER had a mouse in that trap location

I've never seen a stainless tin cat either.  Do as others have stated, risk assess the area and the need for the trap location, and just use the cheap galvanized and replace as needed.  

Plastic, yes. I ran a FS program in a salt manufacturer (ammonium chloride and ammonium sulfate) and it was hell on regular tin cats. I ended up keeping my own stock of both tin and plastic and the PCO would replace as needed. I'd keep the plastic in high dust areas and tin in warehousing.

Sometimes I felt like it was more trouble than it was worth; I still needed to replace the plastics on a somewhat regular basis, and they were quite a bit more expensive than the cheap tin cats.
