AG walls

Are you sure the pool is steel? I have a round 27' Esther Williams (sister company to JW) and my pool walls look like yours(slat construction) and it is made of aluminium. Have you tried a magnet on them to verify they are steel? The only reason I ask is if you have pressure treated directly in contact with aluminium it will severely corrode the aluminium very quickly. You need to place some copper flashing between the wood and the aluminium to prevent galvanic corrosion.

Yes, you are right my pool is aluminium. and not steel...my bad Another way I can get around the "PT" vs aluminium corrosion, is replace the "PT" with kiln dried wood painted. I planned on painting the wood white anyway to make it look better. But, on the "PT" vs aluminium ....The "PT" wood running parallel to the ground on the bottom that you see in the picture have been there against the pool walls since I've owned the house (14years). And there is no signs of corrosion. As for the support of the 2x4s...screwed in outdoor deck screws at an angle at the botton and plus added a metal brace (see bottom of support)...seems pretty sturdy. The flexing isn't enough to rip those screws out.

FYI. Older PT, labeled CCA, was arsenic based and wasn't corrosive to al. New stuff in the last decade, labeled ACQ, is very corrosive. Why the switch? Blame the bs from environmentalists and lawyers.

Ok, I'll go with painted kiln dried 2x4s and keep an eye on it
