Steel Sheet Gauges ......... sheet get thicker as the gauge numbers get lower. (Counter intuitive)Odd that the 36" version has a 7 gauge steel griddle while the 28" has a 10 gauge griddle. I would have thought they would have the same thickness.
The nominal thickness of 10 gauge is 0.134” while the nominal thickness of 7 gauge is 0.179”.
The larger 36” grill therefore has a cooking surface about 33% thicker.
This makes sense given the larger cooking surface and needing to minimize any heat associated distortion.
