Heat angles are simple metal angles: a flat piece of meal with a single break. They are used only with Charbroil and Weber gas grills.
Heat plates are die formed metal plates. Some heat plates resemble angles (see illustration below, center) but have features, such as a more complex shape or vents, not found in angles.
For some models, a choice of grates, plates, and angles are available.
