How To Make A Heat Shield For A Grill

 Steps for constructing a BBQ heat shield

A heat shield protects the food by controlling the temperature and dispersing the heat evenly throughout the grilling surface area. A heat shield preserves the food’s color and flavor as it cooks on the grill. When grilling foods, it’s good to use a heat shield periodically.

If you know how to make a grill heat shield, you can quickly and easily make one for your gas barbeque. If you properly follow the guidelines on making a heat shield for a grill, you will have a homemade heat shield in no time.

Determine the grill length, assemble the necessary staff and equipment, and then follow the steps below.

  • Do not immediately go to the following step—conduct background checks on the individuals who will be working for you before making any agreements.
  • You’ll need a few things to assemble a grill heat shield.
  • A tape measure or a scale 
  •  Material type: Steel or iron? 
  • Drilling machine for holes in the earth
  • Stainless steel screw
  • Rivet gun/welding machine for rivets
  • Hammer
  • Holder
  • Employees cutting steel using a circular saw or a steel cutting machine

How to construct a handmade grill heat shield step by step.

Disassemble the grill and clean up after yourself:

  • Place your BBQ in a well-ventilated area. Verify that your grill is not operating at an excessively high temperature. Allow an hour for cooling if you have just done grilling.
  • Remove the oven’s grill plate. Regardless of whether you’re heating with gas or charcoal, you must first remove the grill plate. Clean the components with fresh water and detergent. One approach is to clean with vinegar.

As follows, determine the size of the heat shield:

  • You have now reached the essential step of this process. With the measuring tape in hand, take a look at the burner. You can install a heat shield over the burner to distribute the heat evenly.
  • If you have many burners, you will want many heat shields. To protect the smaller grill, you may use a single heat shield. It’s all up to you.

Calculate the length of the burner, taking its height and width into account.

Make a design plan:

Creating a heat shield design is straightforward. You may pick a straight line for each burner. Additionally, a Plate Heat Shield is often employed in this case. I would suggest creating a straight line between each burner.

The game starts with a mental note of the dimensions, including height and width.

Make a mark and cut the material:

Create a supply list and mark each item according to the dimensions. Verify that you have taken the correct measurement. It is hard to change your opinion after the material has been cut.

Use a circular saw to ensure that the materials get cut to the correct size. Maintain a minimal amount of extra room. 

Bend the staff if it is made of steel:

Following the cutting of the steel components, they may seem to be flat. It is important to bend them into the shape of an angel. Hold one side of the steel with the holder while bending the other side with your hands.

With the use of a hammer, it is possible to bend even the hardest materials. A piece of welding equipment might be undertaken to join two dissimilar materials.

Components Welding:

Weld the bent portions back together if necessary. Take steps to protect yourself and others safe when welding the components. Welding is necessary to build a single shield cover for a group of burners. By bending the steel at a 45-degree angle, you may cover a single burner without welding anything together.

To attach the heat shield, drill two holes on each side:

Use the drill machine to drill holes of varying sizes into the grill’s many surfaces. ​The holes must be suitably set. To screw the heat shield into those holes, you’ll need a screwdriver.

HeatShield must be set as follows:

However, It is advisable to clean the newly formed heat shield with vinegar and freshwater. Everything will dry out in the air. At this stage, place the heat shield on top of the grill. Examine the shield’s placement to see if it can fully cover the burner.

Proceed to the following stage if everything seems to be in order.

Dismantle the shield

Dismantle the heat shield. Screws, in my opinion, are chosen for various applications. By unscrewing the screws, you may easily remove the shield for cleaning. But, if you solder the shield together, it becomes permanent. There will be no way to clean the burner.


This must be finished by now. Secure the grill plate in position over the heat shield. The heat shield should be gleaming from underneath.

Turn on the burner and use a thermometer to check the temperature. Examine each side of the grill to see whether the shield can transmit heat evenly throughout.

Materials used in the production process that function as a heat shield

Aluminum Stainless Steel: Due to its corrosion resistance, stainless steel is the most used material for grill heat shields. This steel-friendly equipment is straightforward to use. The most pervasive aspect of this information is its accessibility.

The materials in the discussion are aluminum and silicon alloys. Aluminum steel has two unique properties. The most significant property of this steel is its resistance to melting at elevated temperatures. This steel is appropriate for use with a charcoal grill.

Consider a ceramic heat barrier for your barbecue. This heat barrier will likely interest those of you who want to grill over charcoal. Ceramics are made from thick soil with metallic minerals.

Cast Iron: Using cast iron for heat shields has long been popular among makers. This modern material works well with both electric and gas grills. In the larger factories, cast iron is used as a heat screen to prevent the boiler from overheating. But, cast iron is resistant to high temperatures. As a consequence, it may become somewhat more costly.

Chromium Plated Steel: Chrome plated steel is a kind of steel that has had the surface treated with chrome. The surface of this steel is easily clean with soap and water. This is the most efficient way of rust prevention.
