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.
