Has cast iron grates that can be flipper for fat grates (sear), or thin grates (grill). Had to scrub off all the rust and season the grates and it is rocking/
It is a cast aluminum grill. Super heavy duty. I thought I would have to do a bunch of work on the hoses, but they are all good.
New burner and deflector plate on the way. Came with the moving warming grate, but it is rusted out and I would never use it.
