How to Determine the Plate Thickness on your Heatlie BBQ

Got an old Heatlie BBBQ and can't remember how thick your cooking plate is? Maybe you've purchased one second hand and aren't sure? See below for information on how to determine your plates details. 

5 mm, 10 mm or 20 mm plate?

All Heatlie barbecues can be purchased with a 5mm, 10mm or 20mm thick plate (IGEs are 5mm and 10mm only). If you’re not sure what the thickness means and what they’re used for, as a general rule of thumb...

  • 5mm - Domestic casual use at home

  • 10mm - Commercial, frequent and extended use

  • 20mm - Teppanyaki style

A 10mm plate provides greater heat retention than the standard 5mm plate and eliminates the chance of plate warping (though this is still nearly impossible on a 5mm too). These plates are used in commercial cooking applications where longer cooking times are required and is the plate of choice for caterers and chefs. Thus, a commercial food service operation or community group (school, sporting club etc.) should always be using a 10mm mild steel plate.

How to Determine Plate Thickness



If you need to know the plate thickness of an existing BBQ, there is a very simple way of measuring.

Measure the outer edge of the plate from top to bottom, then the inner edge from the plate surface to the top of the edge. The difference will be the thickness of your plate.

How to determine plate material?

If you also aren't sure of your plate material, there is really only one way to tell and that is visually. If it's an old cooking plate, mild steel will be black and slick all over like below...

If it's stainless steel, it will have two large discoloured streaks over the burners only...

Other than that, if your plate is stainless steel, you will notice an "S.S" stamped somewhere on the plate. This will be on the rear, non cooking side.
