5 Best Heavy Duty Fireplace Grates of 2022

What Size of Fireplace Grate Do You Need?

It’s no secret that the firebox in your fireplace can get pretty hot irrespective of the fuel source that you use such as wood or coal. As such, incorporating heavy duty fireplace grates in the firebox makes sense. That’s because it contributes towards preventing damage to your bricks or mortared firebox floor and walls for a very long time, despite the abuse and intense temperatures.

Secondly, a grate contributes towards a better fire experience as it is well ventilated and raised off the floor to some degree, allowing for abundant oxygen supply necessary for a quality fire with minimal smoke.

However, wood or coal-burning fireplaces can always be expected to produce smoke. That smoke is managed by how well your fireplace has been constructed with that need in mind. Because a fireplace grate is raised, the clearance from the floor helps suspend the fire closer to the throat of the chimney and making it easier for the smoke to quickly rise into it and lessening the chance of it spilling over into your living space.

While most fireplace grates are made from steel, cast iron, and in some cases stainless steel, they are not equal. These materials are indeed durable, but the construction of the grate and the gauge of material used will determine their degree of longevity.

Grates that bear a lifetime guarantee have been constructed with meticulous care that bears extreme longevity in mind.

Low  quality fireplace grates will tend to rust and warp.

Investing in a heavy duty grate is a good investment as they are made of thick gauge material and come with coating that prevents rust as well as offers effective heat resistance and eliminates the chances of the metal warping as a result of repeated heating and cooling in the course of many fires.

Heavy duty grate options such as the one reviewed in this post will serve you for many years to come while remaining unscathed and unchanged through the years. This applies even if the grate is heavily used. Heavy duty options tend to have a higher price tag for that reason. But then given their longevity and efficiency, they are great value for their price points.

When choosing a heavy duty fireplace grate, you will need to consider the dimensions and type of the fireplace you have. This ensures you purchase the right model that is best suited for your fireplace. You are better placed to make an informed decision as to what sort of grate will work best for your needs if you know the fireplace type you have. For that reason, let’s take a quick peek at fireplace types.

Types of fireplace

Most homes will have traditional fireplaces that fall into two categories below as follows.

1. Standard fireplaces

Standard fireplaces are also often referred to as brick fireplaces. The design usually involves the fireplace inner walls generally angling inward while the back wall tends to either be vertical or have a slight forward tilt. More often than not, standard fireplaces have an opening of about 36″ W x 28″ high x 16″ to 20″ D.

However, some fireplaces can be extra-large beyond these measurements or smaller. Fortunately, heavy duty fireplace grates come in all manner of different sizes to suit a myriad of dimensions. Unless you have a super-sized fireplace, you will likely spot a heavy duty fireplace grate in this post that fits your fireplace unit like a glove.

Alternatively, there’s always the option of having a fire grate custom made for you to suit unique dimensions. Depending on the height of your standard fireplace, you have the option of getting a fireplace grate model with low clearance or zero clearance so that your fire is visible and enjoys good ventilation while your firebox remains protected from direct heat.

But you can also opt for a grate with a higher clearance of up to 4 inches or thereabout based on your preference

2. Rumford fireplaces

Rumford fireplaces are known for their shallower designs with higher openings that are purposed to prevent heat loss through the flue. The design is instead meant to improve heat transfer into your living space.

Because of the shallow and high opening, more heat pours into the room. However, if not properly built smoke too will pour into the room. This fireplace type will effectively expunge smoke and deliver more warmth to your space if built correctly.

If your firebox recedes in width as it goes inward, you want to ensure you buy a grate model that has an adequate front width but with a lesser back width in keeping with the shape of your fireplace. If your firebox is rectangular you can opt for a model of equal width in the front and the back of the unit. You can always choose varied clearances of high or zero based on your needs and preferences.

Over and above the type of fireplace you have, shape and dimensions, there is one more factor to consider when settling for a heavy duty fireplace grate.

If you have a fireplace screen, you want to get a grate that will co-exist perfectly with such an accessory. As far as ventilation goes, the general rule of thumb is to leave at least 3 inches between the firebox walls and the grate. This will ensure an abundant supply of air for a quality fire.

Other fireplaces that benefit from incorporating a high quality heavy duty fire grate are factory-built fireplaces and modular fireplaces. Such fireplaces are built in a factory and then assembled on site.

Now that you have key pointers on what to consider in respect to your fireplace when shopping for a grate, we have lined up 5 top heavy duty fire grates that are worth your consideration because of their high functionality and exceptional durability.
