The Broil King professional deep wok topper is constructed from 1.2mm high grade stainless steel. Its oversized design gives you more cooking space while its deep dish keeps foods contained within the wok. It has oversized stainless steel 10mm handles with forged Broil King logo, and raised square perforation holes add to the rigidity of the design to help keep the food from sticking. A great accessory to have on your BBQ.
