Metal grille

I found a factory who makes perforated steel sheets, but they have several models, the one I like have a 53% of open area, is this too little?
They have other models with 70-73% open area, now the caliber, 22, 20 or 18?
And how to attacht to the cabinet?

I would go with 70% and 18 gauge.

And how to attacht to the cabinet?

No real right way. I like 1" rubber feet (turned upside down) as standoffs when using 3/4" edge bends.
