The stuff they sell at home depot and Lowes worked good for my charcoal box, but is too flimsy for a grill grate. Any Idea where I can get some in a heavier guage? I live in north east Georgia, right next to Chattanooga Tenn. I've noticed some of the pics people have some with a metal border on them. I'm guesing they were either custom, or manufactured with that original smoker. But any help would be appreciated. Someone mentioned getting a cast iron grate, but it's out of my budget.
