Well, that's because heat rises. When hot air from your burning fire pit rises, it needs to be replaced
by cooler air. With a properly sized grate in place, you create an empty space for that cooler air to enter, underneath your fire. That cooler air enhances your fire's draft
as it becomes heated and rises, adding to the upward flow of hot air.
A fire pit grate can make it easier to light a fire in your fire pit because it gives you access to the space
under your fire, where you want to put tinder and kindling. By blowing on hot coals that have fallen through the grate, you can often re-ignite a fire that has gone out.
How to choose the right size fire pit grate:
First, measure the inside diameter of your fire pit.
Then, subtract 4 inches from that diameter
to get the maximum diameter grate for your fire pit. If you want a smaller size, just make it a bit larger diameter than the fires you expect to build.
Next, figure out how tall you want your fire pit grate to be. Your grate can be about 6 to
8 inches below the rim of your fire pit if you want the flames to be above the fire pit's opening. A grate about 12 to 15 inches below the rim of the fire pit will keep the
flames mainly down inside the fire pit. This arrangement is good for conversing with friends across the fire pit.
You can adjust the height of you grate by making the fire pit deeper or shallower by adding or subtracting
gravel at its bottom, or you can order a custom made grate with legs whatever height you want them to be.
Ready to Ship Fire Pit Grates:
Grates available for immediate shipment include hexagonal grates
to fit fire pits between 30 and 45 inches across, and round grates
to fit fire pits between 32 and 38 inches in diameter. The steel bars in the hexagonal grates are 5/8" by 5/8" in the smallest size and 3/4" by 3/4" in the three larger sizes. The round grates are made with steel bar that is 1/2" by 1/2".
The heavier the steel bar, the longer your fire pit grate will last. The smaller the steel bar, the
less you will pay for your grate.
