mounting options for my outdoor screen

[Feaker]

My gunite pool will be mostly out of the ground and I want to attach my movie screen to the back of it in a way that I can take it down when I want to.

I was thinking having them install a couple rows of something like this along the back of it:

FS-200SS AL 48.00 Strut Channel,4 ft. L,Aluminum,12 Gauge | Zoro.com

Order Zoro Select Strut Channel, 4 ft. L, Aluminum, 12 Gauge, FS-200SS AL 48.00 at Zoro.com. Great prices & free shipping on orders over $50 when you sign in or sign up for an account.

Then I could strap my posts and whatever else I want to the back in a way that's not permanent. A couple problems I see is that I have a knife edge along the back so whatever i put back there has to be able to handle chlorine. It seems like nothing really will though.....

Any ideas?

1/2 inch Galvanized bolts sticking out that you can attach to. And replace said attached parts as neccessary ?

Yeah this is kinda what I was thinking as well but won't the galvanized bolts rust? Would that happen in a short period of time?

They shouldn't, at least not quickly.

What about treated 4x4s or 4x6s going up the back wall, just short of the ledge ? You could replace them in 10 years when they rot.

Do you have the space to use a sleeve in concrete?
Pretty low profile and low maintenance. That would give you the ability to use a round or square post for the screen and option to remove the posts when you want to.

Stainless steel?

Stainless steel?

I researched a decent amount after posting last night. there were 3 grades of SS bolts. The highest grade SS had better rust resistance than galvanized, which had better resistance than the 2 lower SS coatings. for the top grade SS and galvanized they are completely impervious until the coating is scratched. So if nothing hits/rubs it and removing the nut is minimal or never, they should both last forever.

Home Depot, for example doesn’t list the SS grade, simply ‘made with SS coating’.
