Awmco Inc. have a stone that you can use on your grill. I have been 
using their Fibrament-D stone in my oven for more than 3 years (15" x 
20" and it's working perfectly for me. But I also have been using my 
old 14" x 16" stone (3/4 inch thick) on my grill since I got the 
fibrament and I never had any problem.
