Shelving for a homemade smoker

[Chevyost]

Hello all,
I am building a smoker out of a commercial fridge and I need to find shelving for it.
I have looked on-line and have not found what I need or they want way too much for them.
Does anyone know where to get shelves? I need them to be 22" x 23" max. The need to be 21"-22" wide.
Thanks.
Craig.

I used racks from out of ovens for mine. Our local town has a junk day once a year I drove around and took them out of ovens sitting out by the curb.
