This 25" round bowl style gas fire pit burner pan is made of from heavy 16 gauge 304 stainless steel that has a 1/2" stainless nipple welded in the center to connect gas supply to bottom side of pan and gas fire ring to top side of pan. All of our bowl style pans are 2-3/8" deep and have a 1-3/8" lip around the top so they can be set in a circular enclosure to support it. We also provide built-in water weep holes in the bottom for drainage. This pan is commonly used with our 18" gas fire ring.
