How to Make a Heat Shield for a Grill

Nothing beats the excellent taste of grilled foods. If you enjoy grilling food, you understand the importance of having a heat shield for your grill. Better yet, making a heat shield for your grill is relatively simple, so long as you have the right materials and know what steps to follow.

This article will explain how to make a heat shield for a grill. We’ll include a list of materials, steps to follow, safety measures, and maintenance tips to make the process as straightforward as possible.

Materials You’ll Need

There are many different types of grills, like gas grills and charcoal grills, so it’s up to you to decide which one to buy. Either way, the following are general materials to use when making a heat shield for a grill:

  • Stainless Steel: This material is usually used because it is corrosion-resistant and does not melt quickly. Moreover, stainless steel is easy to use and access.
  • Cast Iron: Using cast irons when preparing the grill prevents it from overheating. In addition, cast iron works well with electric and gas grills.
  • Chromium-Plated Steel: This material is easy to clean and rust resistant.

While other materials are used when preparing a grill, like a drill and steel cutter or grinder, you should consider the materials mentioned above.

Let’s now look at how you can use the material to make a heat shield for a grill.

How to Make a Heat Shield for a Grill

Here are the steps to follow when preparing a heat shield for a grill:

1.   Clean the Grill

First, take the grill to an open place, remove the grill plate, and clean it with water and some detergents. You can also use vinegar to make it cleaner and a soft cloth soaked in soap to gently remove any dirt for light cleaning.

Don’t forget to rinse it thoroughly to remove any soap residue that could affect the performance of your shield. If the dirt is stubborn, you can use commercial cleaners for cleaning heat shields.

2.   Check the Measurements

Measure the burner’s length, height, and width using a measuring tape or a ruler. You should make sure that your heat shield is just the right size to cover the burner. This way, your heat shield will spread heat equally.

3.   Cut Your Materials

Measure and mark out your materials and cut them out using a grinder with a metal cutting disc or other steel cutting tools. Remember to cut the exact measures, don’t cut them short or too long.

4.   Bend the Steel

After cutting the materials, bend the steel to shape holding it in a vice and bending with multigrips or similar tool. If the steel is extra hard, you can use a hammer to help tap it into shape. If you need to join 2 or more bits together, access to a stick or TIG welder would come in handy.

5.   Drill the Necessary Holes

After that, create holes on the sides of the grill using a drill. Don’t forget to maintain a good distance between the holes because you will screw your shield onto them.

6.   Place the Shield onto Your Grill

Clean your new heat shield using water or vinegar, dry it and place it perfectly on the grill. Remember to check whether it covers the burner properly or not. You will have to make a new heat shield again if it doesn’t.

7.   Fix the Heat Shield in Place

After placing the heat shield, screw it into the final position. When you want to clean it, you can easily unscrew it. That’s why it is a good idea not to weld it directly to the grill.

Safety Instructions to Follow

While making your heat shield, it’s good to follow some basic safety precautions.

First, use the appropriate protective equipment such as protective glasses, ear muffs, and gloves when making your grill shield. Wearing safety welding goggles is a must while cutting the metal to prevent shards of steel from reaching your eyes.

Secondly, ensure that the grill is cool while working on the project. If it’s hot, give it enough time to cool down before working on it.

In addition, cut the materials somewhere on a flat surface, like on concrete or a welding table. Also, ensure that you don’t make a direct connection between the heat source and your heat shield.

Lastly, don’t place your heat shield above the metal grill.

Why Use a Heat Shield

A heat shield for a grill is generally made from metal and varies in thickness. Using a heat shield on your grill will help prevent flare ups that burn your food, but also stop the fats and oils from hitting the burners to ensure a longer life.

Over time, the fats from your meat can clog up your gas grill burners so using a heat shield helps to prolong the life of your burners.

The shield will help to distribute the heat evenly up to the grill grate avoiding hot spots around your grill, making it easier to use while cooking your BBQ.

Easy to Clean and Transport

Heat shields are open, making them easy to clean. That way, they don’t harbor microorganisms or accumulate food leftovers that might lead to the growth of harmful organisms.

On the other hand, heat shields for grills are small and very light, making them very easy to transport. Lastly, they don’t harm your grill, whether gas or charcoal.

Affordable Materials

The materials used to make heat shields are cheap, durable, and available in most hardware stores. Therefore, it is easy to replace any part if it collapses.

Stress-Free Cooking

A heat shield for a grill absorbs heat and disperses it consistently throughout the grill’s surface. This prevents uneven cooking, evaporates food drippings, and adds flavor to the food. Most people use it to grill their chicken kebabs, meatballs, or bison burgers.

How to Maintain Your Heat Shield for a Grill

Taking good care of your shield is vital to ensure that it stays in top shape for a long time. For insurance purposes, you need to check your heat shield regularly by inspecting if there are any cracks or holes. If you find any damaged items, don’t hesitate to repair them.

Moreover, keep your heat shield clean by wiping it down using a soft cloth, water, and mild soap. However, don’t use harsh chemicals or cleaners when cleaning your heat shield. Lastly, store your heat shield in a cool and dry place when not in use.

By following the above tips, you will contribute to extending the durability of your heat shield as well as keeping it in good condition.


Making a heat shield for a grill at home will allow you to have a good time while eating your favorite grilled foods like vegetables and meat. Heat shields are not complicated to make, use, and maintain. Moreover, the materials used to make your own are affordable and readily available.

Therefore, following the DIY steps and guidelines discussed above, you can make yourself a perfect heat shield to enjoy your barbecue parties. Lastly, follow the safety precautions because you will be using heavy tools like drilling and welding machines, which can be dangerous if mishandled.

Above all, remember to clean your shield after using it, and don’t store it when not dry to avoid rusting.
