The cooking grate is made of 304 grade stainless steel and has a hinge section on it for the ease of adding more wood chunks or wood chips during smoking.
The Kamado Joe has a stainless steel vent in the bottom made of 304 stainless. Which has a very wide opening to allow a good air flow for high temp cook. Also the vent opens and closes very easily. I personally think they should of had a screen on the opening to prevent ashes or sparks to fall out which can be a fire safety hazard. Also with their wide opening of the vent makes it really easy in the removal and cleaning of ashes.
UPDATE: I have been inform by Bobby Brennan the owner of Kamado Joe that all grills will have screens installed on them in 2012.
The Kamado Joe is available in Halifax, NS from Heritage Hearth in Bayers Lake industrial park.
