Edges in deck level perimeter overflow -slope or not?

[niki2021]

Dear forum guests,

i would like to appreciate your advice and professional help.

We are planning to build the perimeter deck -level overflow pool with overflow channel, covered by steel grates later.

The question is: whether we need to use some degree slope towards the inside pool for pool edges, so they will be partially underwater.
If yes, then what what will be angle slope (how many degree or mm ) per cm or any?

And is it possible to do edges with no slope in such kind of pool type?

For example, the attached pool is stated as overflow too.

For our edges the finishes are: coping tile or mosaics.

Will be grateful for your answers.

Best regards, Ani

Stainless steel grates?
Sorry I have never built one of these, used mainly in hotels etc indoors but certainly no where near any vegetation that could wash in.
Suggest you find a hotel pool etc and measure it. Sorry.

it is not about the grate...

Yes I understood that but as I said never built one of these pools.
