The grill grate is an essential part of your cooker because it is in direct contact with your food.
You want a cooking surface that gives you excellent heat transfer, keeps the food from sticking, and is hard wearing.
Choosing the right grill grate is a big decision, as it can affect how your food cooks. Making that choice can be difficult as grill manufacturers love to use a lot of marketing jargon to describe their grates.
To make things as simple as possible, we’ll be breaking down the different kinds of grill grates. Then giving you the information you need to make the right choice.

What types of grill grate are available?
Most grill grates are made of cast iron, stainless steel or one of those base materials covered in an enamel coating.
There is some debate about which grill grate material gives the best results, so we’ll be covering each one in detail and providing a list of pros and cons.
1. Stainless steel grill grates
Stainless steel grates are the most affordable option available. They tend to be lightweight, which makes them easy to move which is helpful if you need to access the coals underneath.
The low weight also means a stainless steel grills heat up quickly. However, because they tend to be thinner they don’t retain heat very well
Proper stainless steel is highly corrosion resistant, but not 100% corrosion proof. Over time, the heat of the coals and regular cleaning will degrade the surface of your grill grate.
This creates a rough surface that is prone to corrosion and can make food stick.
- Light and easy to move around
- Heats up quickly
- Very corrosion resistant when new
- Cooking surface degrades over time
- Wear and tear can cause food to stick
- Low heat retention
2. Cast iron grill grates
Cast iron grill grates have an excellent reputation for heat retention and producing an even cooking temperature.
The thicker cast iron takes a little longer to heat up than stainless steel. But, once they are up to cooking temperature, you can expect excellent heat transfer and bold sear marks.
The downside of a cast iron grill is that it is heavy and high maintenance.
A heavy grate can make it difficult to access your coals and move the grate around when you need to clean it.
The porous surface of a cast iron grate is prone to rust and needs to be regularly maintained. Correctly maintained and cleaned of rust, however, cast iron grill plates are incredibly durable and will probably outlast your cooker.
- Great heat retention
- Produces an even cooking temperature
- Very durable if properly maintained
- Produces great sear marks
- Prone to corrosion
- Requires constant maintenance
- Needs to be seasoned to become non-stick
3. Enamel coated grill grates
Enamel grill grates are standard stainless steel or cast iron grills coated in a smooth enamel. This coating creates a non-stick layer and also prevents the metal surface from corroding.
While an enamel layer does solve some of the corrosions issues of cast iron and heat retention issues of stainless steel, it does have its drawbacks.
The enamel layer can chip during cleaning, allowing in moisture that causes the surface underneath to rust. A chipped enamel grill grate also quickly loses its non-stick properties.
- Creates better heat retention on a stainless steel grill
- Prevents corrosion on a cast iron grill
- Adds an extra non-stick coating
- Prone to chipping if not cleaned correctly
- Loses many of its benefits once damaged
So which grill grate is best?
Overall, cast iron grill grates offer the best cooking surface but with extra up keep required.
You will need to work a little harder to keep your cast iron grill grate in premium condition. It will need to be regularly seasoned to keep it non-stick and rust free.
In return, you’ll get great heat retention and distribution along with bold sear marks. The thicker cast iron grill also works better when cooking delicate cuts, like fish or thin slices of chicken.
It might be tempting to opt for an enamel-coated cast iron grate to increase its corrosion resistance. The problem with that is the enamel is often far less durable than the cast iron its covering.
Cracked enamel lets in moisture which rusts the iron underneath and that can be hard to get rid of. That’s why we recommend a more straightforward combination of a standard cast iron grill grate and good old fashioned elbow grease!

Cleaning and caring for your grill grate
Stainless steel grill grates are easy to clean. Simply spread some aluminum foil over the grate to help burn off the cooking residue and then scrub with a nylon brush.
After cooking, burn as much residue as possible off your cast iron grate. Then, when it is cool, remove any remaining residue with a grill brush and scraper.
Cast iron grills need to be “Seasoned” with oil. This fills in their porous surface with a polymerized layer that prevents corrosion and stops food from sticking. This needs to be done after every use.
The best way to do this is to heat your grill grate slightly to warm it and ensure it is dry. Then apply a thin layer of vegetable oil with kitchen towel.
We go into more detail in our guide to caring for your cast iron grill grates.
To avoid damaging your enamel layer, it’s best to use a brass bristle brush, rather than a scraper, to clean an enamel-coated grill. Be careful not to drop your enamel-coated grill, as this can fracture the coating.
Find the grill grate that’s right for you
