The only issue with those are flammibility. When working with hazmat metal containers are required in industry settings. Flam lockers are $$$$$$$. Metal file cabinets are a much cheaper alternative.
Remember the old wooden soda pop 24 bottle crates? If you could find those!!
A metal toolbox tray could work. I am using one, but have more spray cans, tubes of glue, spray WD 40, gold mist spay, glues and no place to organize them.
So most of them sit in the old metal paint buckets. (New ones are plastic).
