That's what I do. Mine are steel and hold 6 tenners each shelf. 6' long, 6' tall, 24" wide. I use 3 shelves. I use 3/4" OSB on top of the wire shelves for extra durability. Each shelf has a crossbeam to reduce torquing. I get them from Menards.
You can also piece together what you need if desired. Each endcap, each shelf, wire grate, etc.
