Cast Stainless Steel Burner Comparison

All stainless steel burners are not created equal. When comparing burner systems, there are a few key points to look for. Most manufacturers use stainless steel sheet metal to make their burner systems. The downside of sheet metal burners is that they are prone to a process called burn-through. The manufacturer's warranty covers sheet metal burners against rust-through (see photo below), but does not cover against burn-through. To combat burn-through, select manufacturers use CAST stainless steel burners. The warranty on these burners does cover burn-through as well as rust-through, twisting, warping and any other problems.

Compared side by side, it is plain to see that, where a sheet metal burner is not as thick as a U.S. quarter, a cast stainless steel burner is a full ¼ INCH thick. Along with being thicker, note the placement of the burner ports on the side of the burner. On the sheet metal burners, the ports are exposed to grease drippings, and food particles, which can clog the ports and speed up the burn-through process. The cast burner is designed with a protective ridge, so that drippings cannot contact the ports.
