Putting a grate in my firebox to get it up a little higher off the floor. Want to use a paint roller screen (for a 5 gal bucket) purchased at Home Depot. Not sure what it's made of, but it's shiny steel and magnetic (so not aluminium). Any recommendations (or cautions?). I'm burning a stack of coals on it now to see how it holds up, and check for noxious fumes. Nothing so far. Picture below; if you've used one you'll recognize it right away.
Appreciate any feedback;
