Question about green treated lumber( fish house)

[Swampthing]

I am rebiulding the floor of a fish house i just bought. The house was a wood floor ( 2x4) with plywood on top. The guy built the main frame out of angle iron. Then the wood floor sits inside the angle iron frame and wheels. The old floor was'nt treated and some rot. My question is if I use ground contact green treated lumber and it rests on the angle iron frame will I have corrosion issue. Will I have to use some type of buffer between the lumber and iron. I already bought hot dipped galvanized bolts to attach floor to steel frame. I was most worried about the bottom side of 2x4. Any ideas or tips would be great.

you should be good.....it is treated

If you're worried put a layer of felt, tar paper, between the treaded and metal frame.

Im thinking somewhere along those lines.

Not really worried about treated more worried about metal degradation with the high copper content in treated.

I would use sill seal Styrofoam.

could you take a wire wheel to the steel to clean it and then spray some truck bed liner (or just paint) on the steel? Not perfect but would probably slow corrosion for a few yrs

This is probably your best bed.

I was thinking mabey useing the old inner tube trick, like some of us have on our lone wolf stands. I could get them cheap and cut'em up into strips. That might prevent the chemical oxidation.

Good idea on the sill seal, thanks. Um sure its pretty cheap. I would need 30'.

Yeah it's cheap, a local lumber yard will have it.

I used to sell building materials to contractors and they often had the same question. Treated lumber is pumped to capacity with chemicals in order to prevent absorption of water therefore preventing rot. It will slowly oxidize steel that is not coated, which is why galvanized hardware is always recommended with treated lumber. You can use tar paper between the two or something (laquer/stain) with an oil base, even a light coat of chemical resistant spray paint will isolate the metal enough to prevent the lumber chems from oxidizing the metal. Use what you have available, i wouldn't worry about nonstructural component contact. Even a thin layer of rubber/plastic at the joint should do the job for years, especially if the joint is in compression.

Sounds like a contractor statement there.
