Which grate material is best for grilling?

The important thing to remember when looking at grates is that the material used should be strong and durable. If you choose grates that are thin and of poor quality, the heat from grilling will wear them down quickly. Grate options typically include steel, stainless steel, porcelain covered steel and cast iron. Each requires a different type of maintenance. To keep grates in good condition for a longer period of time, you want to be sure and clean your grates regularly and avoid chipping as much as possible.

  • Steel—Plain steel can quickly develop chips, making the grate uneven, and can cause food to stick.
  • Stainless Steel—Stainless steel can keep its non-stick longer than steel, but the porcelain covered steel or the cast iron are still going to be longer lasting.
  • Porcelain Covered Steel—When the porcelain cover chips, the exposed metal tends to rust. To avoid chipping do not use metal scrapers when cleaning the grates. Instead, use bristle brushes.
  • Cast Iron—Cast iron grates get very hot and hold in a lot of heat, helping to cook the meat faster. But these grates take a bit more maintenance than the other options, as they should be rubbed down with oil after every use. This helps avoid rusting.
