Home Depot shelf viable?

[Dreamville32]

Hi reefers I want to put a rack in my room to hold a 10, 20, and 4 gallon tanks that I have and I saw this one in Home Depot and was just wondering if you guys think it would hold up? It says each shelf supposedly holds 350lbs

would probably hold the tanks fine but id be worried about rust... those grate shelves rust easily over time
