Traeger Flatrock vs Traeger Irontop
Traeger's cheaper griddle is the bigger one: 648 sq in at $599.99 against 594 at $999.99. What the Flatrock's three insulated zones cost.
We pick the Traeger Irontop 4-Burner Griddle
The Irontop is more griddle for less money, and it does not need an outlet. It puts 48,000 BTU across 648 sq in (74 BTU per square inch) at $599.99, with piezo ignition, no battery and no app. The Flatrock asks $999.99 for 594 sq in and 47,000 BTU, or about 79 BTU per square inch, and spends the difference on three insulated cooking zones, per-burner flame lights and a weighing fuel gauge, all of which want the grill plugged in. Our reviews score them 8.36 and 8.17.
What actually differs
-
More surface, $400 less
648 sq in against 594, at $599.99 against $999.99. Our Irontop review puts it plainly: the cheaper Traeger griddle is the bigger one.
-
Zones against a flat plate
The Flatrock separates its three zones with insulation, so a cool side genuinely stays cool. Nothing on the Irontop separates the four burners. If you cook eggs beside steak, that is what you are buying.
-
A cord, and a warranty that excludes warping
The Flatrock's ignition, flame lights and gauge all need mains power; the Irontop needs nothing. And the Flatrock's five years covers body and legs while the cooktop gets one year with warping excluded. The Irontop carries three years.
