Search By Dimension Any BBQ Grill Replacement Heat Shield Radiant.

Heat plates are often refered by different terms depending on how a particular barbecue brand see the use of the plate. Below the cooking grate and above the grill burners there will be a heat shield with the role of vaporizing or radiating or shielding falling grease and spreading or diffusing rising heat from the flames on the burner. This grill part is called a Heat Shiled, a Radiant, a Heat Plate, Vaporizer or many other names. Many heat shields are manufactured by heavier or better materials depending on the grill and where the barbecue parts are manufactured. Some steel heat plates are coated with a porcelain enamel for protection. Some still use cast iron which helps with heat conduction. The best of the vaporizer shields are stainless steel and American 304 stainless steel is designed to last forever if properly maintained. Finally, some heat shields are designed to be briquette supports that have briquettes, lava rocks, rods or some other material that is designed to conduct heat to radiate at the grilling surface and vaporize drippings.

Critical Dimension:

The critical dimension for a heat plate to fit is determined by the way the plate mounts in the grill housing. Most plates mount front and back, so for these plates this dimension (depth) is critical. A significant minority of plates, however, mount left and right. For these plates, the width dimension is critical. We list heat plates in descending order of the critical dimension, so to find a replacement part, you must first make note of how the original part mounts in your grill, front and back or left and right.

As a general rule, a replacement heat plate must be within three sixteenths of an inch (0.1875) of the original part in the critical dimension to fit correctly. You should measure your grill to make sure the replacement plate will fit before buying a part with a critical dimension different from that of the original part.

The other dimension of a heat plate is much less critical. A replacement can be a few inches narrower or shorter than the original and still be useful.

measuring by dimension for replacement bbq grill heat shield

Click the Appropriate Depth range (Front to Back measurement) to find a replacement heat plate for your grill.

The Heat Shields will mount front and back in the fire box of the barbecue and a heat shield that does not look like the original will still diffuse heat and vaporize grease so long as the depth will fit the barbecue grill.

dcs radiant tray shield with ceramic rods

This is the Radiant tray used in many Dynamic Cooking Systems barbecue grill. The 304 stainless steel radiant shield has porcelain rods to conduct heat locked into the heat shield. The rods heat up when the barbecue heats up and the rods radiate heat at the grilling surface to add heat where grilling is happening. The heat shield also vaporizes dripping marinades and grease which both adds flavor to the convectional heat in the barbecue and protects the burner from getting dirty with drippings.

In this image there is a heat shield below the U shaped burner. DCS calls their lower floor of the barbecue heat plates which can be misleading. The idea of the barbecue is to create an all-encompassing heat in the entire barbecue so the entire grill grate area heats up together by transferring heat in the air trapped inside the hood of the barbecue.

This image shows an older design by DCS which has a stainless steel heat shield that was designed to use lava rocks that were dumped on the heat shield. The original idea was that the convectional heat -- heat conduction in air trapped in the hood -- would be added to be the heat radiating off the lava rocks. These conduction materials get hot and radiate heat for extra grilling heat for searing food at the grilling surface. Dcs went to the porcelain rods from the lava rocks but some DCS gas grills also only had stainless heat shields built heavy enough and spaced properly as a vaporizing shield.

As another example this Thermal Engineering Corporation gas grill uses a black piece of glass as a heat shield vaporizing radiant over their stainless steel burner. Infrared gas grills are designed to always grill above nine-hundred degrees for searing steaks. The glass heat plate allows grease to be vaporized as it drips while diffusing heat to the grill grate surface.
