How well does aluminum hold up in chlorinated pool water?

Question

I need to install hand rails around a hot tub and wonder if aluminum would work well.

Answer 1

Aluminum is not a good choice, even if it's anodized, painted, or powder coated.  Pool water is corrosive mostly due to the chloride from chlorination.  Steel is slightly less prone to corrosion.  Plastic or fiberglass is the best choice.  

Answer 2

It should hold up well I don't think there would be any reaction. They use aluminum railings as stairs for large pools. The aluminum might be coated with something else though. Aluminum usually forms a thin coat of Aluminum Oxide, Al2O3, so it should prevent it from further oxidation.  

Answer 3

Bad idea, it will corrode.  Better are pool rails made from steel and powder coated in white, or light, not chromed, so you don't get burned.

You're welcome!!
